steaming so i shut off the engine right away and i don't think there's any

right away and i don't think there's any

right away and i don't think there's any damage done to

damage done to

damage done to the motor i believe it's the expansion

the motor i believe it's the expansion

the motor i believe it's the expansion tank that finally gave out

tank that finally gave out

tank that finally gave out but i'm not 100 sure so let's take it

but i'm not 100 sure so let's take it

but i'm not 100 sure so let's take it apart and see what it is

apart and see what it is

apart and see what it is exactly so the coolant leak was roughly

exactly so the coolant leak was roughly

exactly so the coolant leak was roughly right about

right about

right about here that's why i think it was the

here that's why i think it was the

here that's why i think it was the expansion tank or one of the connectors

the hoses that blew out so um let's take out the intake

so um let's take out the intake

so um let's take out the intake the ducting and see what we can see

the ducting and see what we can see

the ducting and see what we can see with the air box and the ducting removed

with the air box and the ducting removed

with the air box and the ducting removed i can get

i can get

i can get a clear view of the expansion tank

a clear view of the expansion tank

a clear view of the expansion tank however because it would oh

however because it would oh

however because it would oh is this the crack right here

is this the crack right here

is this the crack right here i think that's it right there i don't

i think that's it right there i don't

i think that's it right there i don't know if you can see that

know if you can see that

know if you can see that see if it can focus a little bit better

see if it can focus a little bit better

see if it can focus a little bit better but there is a

but there is a

but there is a crack right on the edge of the expansion

crack right on the edge of the expansion

crack right on the edge of the expansion tank

so yeah looks like uh the expansion tank

so yeah looks like uh the expansion tank

so yeah looks like uh the expansion tank has to come out and get replaced

has to come out and get replaced

has to come out and get replaced so on these e46 expansion tanks you've

so on these e46 expansion tanks you've

so on these e46 expansion tanks you've got the main hose the main upper hose

got the main hose the main upper hose

got the main hose the main upper hose right here

right here

right here so we've got to take this guy off they

so we've got to take this guy off they

so we've got to take this guy off they are these little clips

right here and then there is one tab on the bottom

and then there is one tab on the bottom

and then there is one tab on the bottom along with the sensor and i'll show you

along with the sensor and i'll show you

along with the sensor and i'll show you once i get it out

once i get it out

once i get it out these two hoses do not need to be

these two hoses do not need to be

these two hoses do not need to be disconnected you can stay

disconnected you can stay

disconnected you can stay where they are they actually go into the

where they are they actually go into the

where they are they actually go into the i think it goes into the radiator i'm

i think it goes into the radiator i'm

this plastic end you have to get a new one from bmw now

you have to get a new one from bmw now

you have to get a new one from bmw now just to get this

just to get this

just to get this hose and the clips ready for

hose and the clips ready for

hose and the clips ready for reinstallation you make sure you want to

reinstallation you make sure you want to

reinstallation you make sure you want to put

put

put the clips back into position so when you

the clips back into position so when you

the clips back into position so when you push it into the um new expansion tank

push it into the um new expansion tank

push it into the um new expansion tank it just clips right in so now that we

it just clips right in so now that we

it just clips right in so now that we got the

got the

got the top hose out of the way next we're gonna

top hose out of the way next we're gonna

top hose out of the way next we're gonna have to work

have to work

have to work on this guy now as you can see

on this guy now as you can see

on this guy now as you can see right here focus

right here focus

right here focus it's actually the same style clip

it's actually the same style clip

it's actually the same style clip as the one on top so

as the one on top so

as the one on top so let's do this pull it up slightly

let's do this pull it up slightly

let's do this pull it up slightly until it clicks

should come out

should come out

should come out yep and there's water coming out so

yep and there's water coming out so

yep and there's water coming out so that's fine let's just move that guy out

that's fine let's just move that guy out

that's fine let's just move that guy out of the way as well

last but not least there is a connection

last but not least there is a connection

last but not least there is a connection on the bottom

on the bottom

on the bottom of the expansion tank and i don't know

of the expansion tank and i don't know

of the expansion tank and i don't know if you can see that but there is a

if you can see that but there is a

if you can see that but there is a little white

little white

little white tab right at the bottom so if you look

tab right at the bottom so if you look

tab right at the bottom so if you look this is the front of the car obviously

this is the front of the car obviously

this is the front of the car obviously this expansion tank and it's

this expansion tank and it's

this expansion tank and it's right down there there is a little white

right down there there is a little white

right down there there is a little white tab

tab

tab you want to pull that towards the

you want to pull that towards the

you want to pull that towards the passenger side and then it will release

passenger side and then it will release

passenger side and then it will release the expansion tank but don't yank it out

the expansion tank but don't yank it out

the expansion tank but don't yank it out all the way

all the way

all the way um the uh there is one sensor underneath

um the uh there is one sensor underneath

um the uh there is one sensor underneath that i

that i

that i think is still there so let me go ahead

think is still there so let me go ahead

think is still there so let me go ahead and give this a shot

okay so get this guy out of the way and

okay so get this guy out of the way and

okay so get this guy out of the way and then you want to pull

then you want to pull

then you want to pull straight up and there's the sound of a

straight up and there's the sound of a

straight up and there's the sound of a mess happening

mess happening

mess happening and this guy kind of comes out now

and this guy kind of comes out now

and this guy kind of comes out now there is a sensor still

there is a sensor still

there is a sensor still underneath here you want to be careful

underneath here you want to be careful

underneath here you want to be careful which is this guy right here you can see

which is this guy right here you can see

which is this guy right here you can see that

that

that right there that little white tab and

right there that little white tab and

right there that little white tab and that one

that one

that one i believe you spin it

i believe you spin it

i believe you spin it one way or another and it's supposed to

one way or another and it's supposed to

one way or another and it's supposed to come out

come out

come out there you go that's the sensor right

there you go that's the sensor right

there you go that's the sensor right there it's the

there it's the

there it's the level sensor so you spin that clockwise

level sensor so you spin that clockwise

level sensor so you spin that clockwise and it comes out so there is

and it comes out so there is

and it comes out so there is one broken expansion tank you can see

one broken expansion tank you can see

one broken expansion tank you can see the crack

the crack

the crack all the way along the side so i believe

all the way along the side so i believe

all the way along the side so i believe this one is the original one for this

this one is the original one for this

this one is the original one for this car so it had 140 something thousand

car so it had 140 something thousand

car so it had 140 something thousand miles on it

miles on it

miles on it so it was definitely due this is the old

so it was definitely due this is the old

so it was definitely due this is the old expansion tank

expansion tank

expansion tank that blew up and as you can see right

that blew up and as you can see right

that blew up and as you can see right here is the crack

here is the crack

here is the crack it goes all the way down like i said

it goes all the way down like i said

it goes all the way down like i said this one had

this one had

this one had a 140 something thousand miles on it so

a 140 something thousand miles on it so

a 140 something thousand miles on it so it definitely was due um i do have

it definitely was due um i do have

it definitely was due um i do have a spare one here i think this is not a

a spare one here i think this is not a

a spare one here i think this is not a an oem one this is an aftermarket china

an oem one this is an aftermarket china

an oem one this is an aftermarket china one

one

one and um this one looks almost the same i

and um this one looks almost the same i

and um this one looks almost the same i forget why i didn't use this

forget why i didn't use this

forget why i didn't use this but some parts that you want to salvage

but some parts that you want to salvage

but some parts that you want to salvage from your

from your

from your current setup is definitely this clip

current setup is definitely this clip

current setup is definitely this clip right here

right here

right here so this guy actually comes off and you

so this guy actually comes off and you

so this guy actually comes off and you want to put it on to the new one

want to put it on to the new one

want to put it on to the new one and then of course your radiator cap

and then of course your radiator cap

and then of course your radiator cap you want to switch that over so um yeah

you want to switch that over so um yeah

you want to switch that over so um yeah let me switch these guys over

let me switch these guys over

let me switch these guys over and um we should be ready to put them in

and um we should be ready to put them in

and um we should be ready to put them in this guy is

this guy is

this guy is relatively simple you just pull it

relatively simple you just pull it

relatively simple you just pull it outwards a little bit

outwards a little bit

outwards a little bit and it falls right out so on the new one

and it falls right out so on the new one

and it falls right out so on the new one you want to put the clip

you want to put the clip

you want to put the clip into the groove on one side into the

into the groove on one side into the

into the groove on one side into the groove on the other side

groove on the other side

groove on the other side and see basically when you pull that

and see basically when you pull that

and see basically when you pull that releases it and you snap it in

releases it and you snap it in

releases it and you snap it in it locks it in place so um to install it

it locks it in place so um to install it

it locks it in place so um to install it you should have it snapped in

you should have it snapped in

you should have it snapped in but we'll see what happens let me see if

but we'll see what happens let me see if

but we'll see what happens let me see if i can get this guy since it's not an oem

i can get this guy since it's not an oem

i can get this guy since it's not an oem part and the hoses are relatively old

part and the hoses are relatively old

part and the hoses are relatively old already

already

already um let's see if it'll snap in really

um let's see if it'll snap in really

um let's see if it'll snap in really nice for me

nice for me

nice for me so first of all let's get the sensor

so first of all let's get the sensor

so first of all let's get the sensor back

back

back into the bottom the sensor goes in right

into the bottom the sensor goes in right

into the bottom the sensor goes in right there

i don't know if i can get a good camera

i don't know if i can get a good camera

i don't know if i can get a good camera angle on this

angle on this

angle on this but trust me it's going in

but trust me it's going in

but trust me it's going in so i was able to get the sensor

so i was able to get the sensor

so i was able to get the sensor connected underneath

connected underneath

connected underneath now we have to slide the actual tank

now we have to slide the actual tank

now we have to slide the actual tank into its proper slot now if you remember

into its proper slot now if you remember

into its proper slot now if you remember there is a little tab right here where

there is a little tab right here where

there is a little tab right here where my finger is right here

my finger is right here

my finger is right here it actually goes into the plastic

it actually goes into the plastic

it actually goes into the plastic bracket

bracket

bracket and then you push down on it so let me

and then you push down on it so let me

and then you push down on it so let me show you actually

show you actually

show you actually on the other the old one to see where

on the other the old one to see where

on the other the old one to see where that exactly slides into

that exactly slides into

that exactly slides into so on this old expansion tank you can

so on this old expansion tank you can

so on this old expansion tank you can see it clearly

see it clearly

see it clearly this is the little tab that needs to be

this is the little tab that needs to be

this is the little tab that needs to be sliding into

sliding into

sliding into the little plastic bracket on the

the little plastic bracket on the

the little plastic bracket on the radiator so

radiator so

radiator so basically what you do you push it in and

basically what you do you push it in and

basically what you do you push it in and then

then

then push down and that's how the expansion

push down and that's how the expansion

push down and that's how the expansion tank will properly

tank will properly

tank will properly seat hopefully the two

seat hopefully the two

seat hopefully the two hoses on the bottom will also click into

hoses on the bottom will also click into

hoses on the bottom will also click into place when that happens

place when that happens

place when that happens if not we might have to push the hoses

if not we might have to push the hoses

if not we might have to push the hoses up a little bit

up a little bit

up a little bit just to get them to snap in but let's

just to get them to snap in but let's

just to get them to snap in but let's hope for the best

hope for the best

hope for the best line up this plastic tab right here

i think that's in place but i didn't

i think that's in place but i didn't

i think that's in place but i didn't hear a snap from underneath

hear a snap from underneath

hear a snap from underneath so let's make sure the hoses are

so let's make sure the hoses are

so let's make sure the hoses are connected properly

i think it's in place so a good way to

i think it's in place so a good way to

i think it's in place so a good way to check if your expansion

check if your expansion

check if your expansion tank is seated properly you want to push

tank is seated properly you want to push

tank is seated properly you want to push it forward and back

it forward and back

it forward and back and it should basically move the whole

and it should basically move the whole

and it should basically move the whole radiator with it so that means the

radiator with it so that means the

radiator with it so that means the little

little

little plastic hook is in place and if you want

plastic hook is in place and if you want

plastic hook is in place and if you want to push it pull it upwards

to push it pull it upwards

to push it pull it upwards it doesn't move it doesn't just shoot

it doesn't move it doesn't just shoot

it doesn't move it doesn't just shoot out

out

out so i think we are okay next off we need

so i think we are okay next off we need

so i think we are okay next off we need to connect

to connect

to connect the other two hoses that were here

the other two hoses that were here

the other two hoses that were here it's this guy right here so make sure

it's this guy right here so make sure

it's this guy right here so make sure again

again

again snap the uh metal clips

snap the uh metal clips

snap the uh metal clips back into the hose and then

back into the hose and then

back into the hose and then push it in so that one clicked really

push it in so that one clicked really

push it in so that one clicked really nicely

nicely

nicely and then we've got this one

that also clicked really nicely okay

that also clicked really nicely okay

that also clicked really nicely okay so now all i gotta do is fill it up with

so now all i gotta do is fill it up with

so now all i gotta do is fill it up with coolant

coolant

coolant run it and see if there's any leaks

so i'm just gonna pour in water for

so i'm just gonna pour in water for

so i'm just gonna pour in water for right now just in case it does leak some

right now just in case it does leak some

right now just in case it does leak some more

more

more um it'll only be water coming out

um it'll only be water coming out

um it'll only be water coming out not actual coolant and for the coolant

not actual coolant and for the coolant

not actual coolant and for the coolant you definitely want the blue bmw stuff

you definitely want the blue bmw stuff

you definitely want the blue bmw stuff um that's what's recommended by the

um that's what's recommended by the

um that's what's recommended by the manufacturer

manufacturer

manufacturer so let's top it up all the way

so let's top it up all the way

so let's top it up all the way because it needs to bleed the system

because it needs to bleed the system

because it needs to bleed the system probably has a lot of air in it

[Applause]

so we're gonna let it run like this for

so we're gonna let it run like this for

so we're gonna let it run like this for maybe like a minute or so and let all

maybe like a minute or so and let all

maybe like a minute or so and let all the air bubbles kind of come out from

the air bubbles kind of come out from

the air bubbles kind of come out from the system

the system

the system and then once that happens i'm gonna go

and then once that happens i'm gonna go

and then once that happens i'm gonna go ahead and cap

ahead and cap

ahead and cap it let the system pressurize and see if

it let the system pressurize and see if

it let the system pressurize and see if there are any more

there are any more

there are any more leaks and then obviously after that

leaks and then obviously after that

leaks and then obviously after that we're gonna wait for it to cool down

we're gonna wait for it to cool down

we're gonna wait for it to cool down and fill up with uh fill it up with

and fill up with uh fill it up with

and fill up with uh fill it up with cooling all over again

cooling all over again

cooling all over again so there's still bubbles coming out

so there's still bubbles coming out

so there's still bubbles coming out however the car is fully warmed up

however the car is fully warmed up

however the car is fully warmed up i'm gonna cap it right now and see if it

i'm gonna cap it right now and see if it

i'm gonna cap it right now and see if it holds pressure

so we're going to let it idle for a

so we're going to let it idle for a

so we're going to let it idle for a little bit longer

little bit longer

little bit longer so now it's actually been roughly about

so now it's actually been roughly about

so now it's actually been roughly about 10-15 minutes

10-15 minutes

10-15 minutes and when you squeeze the hose it is

and when you squeeze the hose it is

and when you squeeze the hose it is hot and it has pressure so that means

hot and it has pressure so that means

hot and it has pressure so that means the

the

the hoses were all clipped in correctly i

hoses were all clipped in correctly i

hoses were all clipped in correctly i wiped down all the areas where there was

wiped down all the areas where there was

wiped down all the areas where there was water where i spilled water

water where i spilled water

water where i spilled water so i know if there's any water dripping

so i know if there's any water dripping

so i know if there's any water dripping and so far there is

and so far there is

and so far there is not so inside the car

not so inside the car

not so inside the car yeah i still have my car seat in here i

yeah i still have my car seat in here i

yeah i still have my car seat in here i need to take this out and

need to take this out and

need to take this out and put the stock seat back in so i can

put the stock seat back in so i can

put the stock seat back in so i can drive it around normally now in here you

drive it around normally now in here you

drive it around normally now in here you can see the temperature is

can see the temperature is

can see the temperature is uh closer to hot don't worry about that

uh closer to hot don't worry about that

uh closer to hot don't worry about that too much because the system's not

too much because the system's not

too much because the system's not properly bled there's probably a lot of

properly bled there's probably a lot of

properly bled there's probably a lot of air pockets in the cooling system

air pockets in the cooling system

air pockets in the cooling system because obviously you know we opened it

because obviously you know we opened it

because obviously you know we opened it up a lot of water ran out and all that

up a lot of water ran out and all that

up a lot of water ran out and all that stuff

stuff

stuff even though we filled it up there's uh

even though we filled it up there's uh

even though we filled it up there's uh air in the system

air in the system

air in the system so what i'm gonna have to do is turn it

so what i'm gonna have to do is turn it

so what i'm gonna have to do is turn it off right now

off right now

off right now let it cool down completely then open

let it cool down completely then open

let it cool down completely then open the radiator cap

the radiator cap

the radiator cap this expansion tank should be close to

this expansion tank should be close to

this expansion tank should be close to empty

empty

empty fill it up with water again and then

fill it up with water again and then

fill it up with water again and then continue the cycle

continue the cycle

continue the cycle so that way we can get all the air

so that way we can get all the air

so that way we can get all the air bubbles out

bubbles out

bubbles out i also let the leader screw loose

i also let the leader screw loose

i also let the leader screw loose slightly

slightly

slightly to relieve the uh air bubble and the air

to relieve the uh air bubble and the air

to relieve the uh air bubble and the air pressure in the system is as you can see

pressure in the system is as you can see

pressure in the system is as you can see this is all air there is no coolant

this is all air there is no coolant

this is all air there is no coolant coming out

coming out

coming out um so there is definitely a lot of air

um so there is definitely a lot of air

um so there is definitely a lot of air trapped in the system

trapped in the system

trapped in the system it's gonna be a long bleeding process

it's gonna be a long bleeding process

it's gonna be a long bleeding process okay so the steam has stopped coming out

okay so the steam has stopped coming out

okay so the steam has stopped coming out of the bleeder valves there shouldn't be

of the bleeder valves there shouldn't be

of the bleeder valves there shouldn't be any more pressure

any more pressure

any more pressure in the system which there isn't the hose

in the system which there isn't the hose

in the system which there isn't the hose you can squeeze

you can squeeze

you can squeeze so that means you can open the radiator

so that means you can open the radiator

so that means you can open the radiator cap

just be careful when you're doing this

just be careful when you're doing this

just be careful when you're doing this hot

hot

hot always use a rag

there we go and clearly the water is

there we go and clearly the water is

there we go and clearly the water is already at the low level so let's fill

already at the low level so let's fill

already at the low level so let's fill it back up

it back up

it back up and redo the process already poured some

and redo the process already poured some

and redo the process already poured some coolant in there

coolant in there

coolant in there and now it's mostly water

and now it's mostly water

and now it's mostly water this time i'm actually going to leave

this time i'm actually going to leave

this time i'm actually going to leave the leader screw slightly open

the leader screw slightly open

the leader screw slightly open and let the water seep out from there

so make sure you fill the water up

so make sure you fill the water up

so make sure you fill the water up completely

completely

completely for the purpose of bleeding um

for the purpose of bleeding um

for the purpose of bleeding um you want the water as full as possible

you want the water as full as possible

you want the water as full as possible any excess water it will bleed out so

any excess water it will bleed out so

any excess water it will bleed out so you won't hurt the engine

you won't hurt the engine

you won't hurt the engine so let's cap this guy

so already you can see the temperature

so already you can see the temperature

so already you can see the temperature is back to

is back to

is back to basically normal i have the heater

basically normal i have the heater

basically normal i have the heater running

running

running because also the heater core might get

because also the heater core might get

because also the heater core might get air trapped in it so you want to bleed

air trapped in it so you want to bleed

air trapped in it so you want to bleed the heat of course this

the heat of course this

the heat of course this uh the heater system also so right now

uh the heater system also so right now

uh the heater system also so right now i don't expect the needle to go any

i don't expect the needle to go any

i don't expect the needle to go any higher than that

higher than that

higher than that but after it fully warms up and the

but after it fully warms up and the

but after it fully warms up and the system

system

system flushes out all the air i will let it

flushes out all the air i will let it
