Rich Harris: if by chance you don't bleed the coolant you will know real quick when you
run down the road with the a/c on...you will peg out red really quick.
Bleed the pressure out by at least taking the care 1/4 of the mile down the
road...then bring it back to make sure the pressure is built up....you
might see your thermostat starting to peg. Just bleed the pressure off and
you are good.
Rich Harris: Be careful pulling on the tank to hard as it does pull on the transmission
cooler box quite hard (raising it up.) Suggest someone hold the box
underneath while one pulls on the tank. I had to use a flat jack and the
bottom of a wooden hammer and lift the tank up with the butt of the hammer
with force from the floor jack to pry it loose.
Josh Hobbs: What if the low coolant level is on. Water doesn't leak when its idle but
when its driven and I get to my destination the red stick indicates there's
no water in it. Water pump was just replaced. Could it just be the
expansion tank.would that solve it or what direction do I need to go.
6041321as: What if my car is loosing cooling water,and from exhaust comes white smoke.
Taste and smeel of smoke is like my coolant water is mixed in work of
engine, like the engine burning water also not just fuel. Tnx
Alexander Vakulenko: the hose coming off the bottom of the expansion tank, I notice it goes into
the front of the engine.. but where exactly does it go? I have a 545i
thekingreyrey: I have a 2003 325i, and it has been leaking anti freeze when its off would
it be the radiator or the expansion tank? Also its been leaking more each
week. If you could help me out that would be awesome! Thanks!
sendthosepixma: Its hard to hear I have a 2001 325ci bmw Is there a sensor connected
to the expansion tank and doesn't it tell you the coolant is low? I
think i need that sensor My car broke down and i had the coolant system
replaced 2 years ago Water pump,, thermostat, pulleys belt expansion tank
My coolant light comes on occasionally and goes out while im driving My
coolant is full to the top and i dont see any leaks on the ground and it
still says low im guessing that sensor went bad with age and need to
find out where its at
tucan452: Need help with this 2005 BMW 325i Oil Cooler Thermostat For Automatic
Lucas Hill: Help!!! This might sound crazy but after replacing my expansion tank, I
cannot get my main hose that has the bleeder screw in it to connect back to
the radiator. I'm pulling with all my strength and it barely even moves.
All the other hoses connect fine. I checked the inside of the hose to see
if there was something in there but it looks just fine. Has anyone seen
this happen before? What do I do ?
Raj D.: CAUTION: don't leave the bleed screw open for too long with engine running.
If you do don't forget to let the engine cool before tightening your bleed
screw (I just broke mine off because it melted after leaving the engine
running with screw open to let air out)
MauricioR23: How do you install the sensor back on. I'm about to replace my radiator
tank next week and it seems like the level sensor can be a bit of a pain.
Also,what's the purpose of pulling out the latch out from the bottom after
removing the tank if you're going to be replacing the tank with a new one?
izzy dontgotONE: Hey man really need help. I have a 98 540i and every once and a while I get
this really bad "burning smoke" smell when I have my heater on. Any
suggestions or tips on how to fix or what the problem may be?
Man Garibay: The worst thing is that the U joints are not interchangeable, so you have
to find a specialty shop that can rebuild the drive shaft. It all started
with a ticking under the center console and it got worse over time, till
the car is just not drivable
klc317: Oh well, radiator is not too difficult and expensive of a job, probably
with the age and mileage it is probably not at full efficiency anyway.
Might as well throw some new hoses on also. Always something!! Keep up the
mbyr31: It never seems to fail....If its not too cold when the car breaks down, its
too hot! I'd still take the heat over the cold though. At least you can
still feel your fingers...LOL! Great work Ed! They sure do pack stuff into
those cars, eh??
Doug Robinson: Thanks Ed. I used your video to learn how to replace my expansion tank.
Everything is running fine now. You are right - you do have to pull really
kattlikzm: Hi My dipstick thingy is at the bottom, and yet the coolant light hasn't
come up on the dashboard yet!? Is it still safe to drive the car?
EdzGarage: I used the green stuff mixed with distilled water.
gvvvv2300: my card is in garage. they told me there is a crack in the tank and it
needs to be replacement. along with this, they are saying there are other
parts which tend to break on e46. how much do you think is it reasonable to
get this job done? thanks a lot in advance.
EdzGarage: You have to bleed the system. I showed how at the end of the video.
WhoSaidTyler: I fell in LOVE with a 2003 525i that actually had a manual trans a while
back...black outside, black inside, wow I wanted that car. Everything I
read on the internet pretty much said the entire cooling system has to be
replaced at some point, either by necessity or pre-emptively. You know you
are working on a Bimmer when you can wear shorts for pretty much any job :-)
carnivore10: Nice work Ed, That O-ring kit you have there looks like a good one. Good
EdzGarage: I would add some coolant. You never know if your level sensor is bad.
7Monte9: Very helpful video. I didn't even take off the front air intake. Just the
air filter box. Its a good idea to change all o-rings while you have
everything apart. Thanks for the video!
vidman008: The stuff I do at work with the juice machines, and water, they are all
sealed with O-Rings.. After a length of time, the O-Rings develope a "Flat"
all the way around them because they've been cramped in the same spot for a
while.. Once the flat wears a little, they will develope a slow drip..
Maybe you'll get Lucky, and it will be a hose leak, rather than your
Radiator.. Good Video.. I feel on the floor laughing when you said you just
have to remove the front of the car.. LMAO.
EdzGarage: Well in this case it was not bad lol They do get stressed and my first one
blew out at 120k miles. Thanks for watching!
Man Garibay: What a coincidence, I just did this job last week at 167k miles... Drove
the car for a couple of days and the drive shaft's carrier bearing went
out. I don't know if the drive shaft is rubbing around the transmission
tunnel or the bearing housing, but it sure makes an awful noise. I have
scheduled a tow truck to transport my car to the BMW tech to get the job
done. I feel this job is too big for me to tackle on my garage floor.
EdzGarage: Yep, it was going anyway... I just know it lol
EdzGarage: The radiator job is next. Looks like it wont be too bad. Thanks for
TheRudenreckless: Info: when pooling the tank up after disconnecting the switches at the
bottom, twist the tank side to side to loosen it up!!! A good video man
thanks for the info but I broke a couple of plastics cuz I couldn't see any
shots of the bottom of the tank and what needed to be disconnected. Other
than that a helpful video.
EdzGarage: This is a very common issue with these cars. I hope I don't have issues
with my carrier bearing now! lol
EdzGarage: No coment? What does coment mean? Thanks for watching!
Tiffany Tran: Just a quick question , s
Kaarle Oulasvirta: Hi! i get it out and now i have put everything back so now i have only to
bleed the airbubbles out of the system like you do at 5:57 -> so is the car
running at the same time and there is in the bottom of the tank one bleed
screw also (blue one), am i going to touch that to? or is it something
else? you change the o ring for that ?
EdzGarage: lol Nope, no more spiders!
dakibmw: Ed, have you replaced ET without actually getting under the car (at all)
and without removing plastic skid plate/cover from under the engine? Thanks.
mike moe: one addition to this when pulling the tank have a new ATT valve ready it
will probably break into pieces when pulling tank
500passwords: the air in my truck isnt working good and all this stuff your doing is
scaring me . lol i was getting ready to recharge it like you did in last
video . but now you got me worried about this tank and stuff :P thumbs up
Henry Lavigne: Hey Ed, can you explain the proper way to place the metal spring that sits
above the trans thermostat in the expansion tank? I think the big end is on
top, but does it seems to sit to one side in there due to some plastic
nubs. Any insights?
tube101ish: great video.. thank you so much for your help
EdzGarage: lol It's been a good car. It has 198k on it now, so things are starting to
go on it. I just need to keep up on it. Thanks Vic!!
EdzGarage: lol you can't get good camera help these days!!! Thanks for watching Buddy!
EdzGarage: First things first... recharge the A/C then you can focus on the other
stuff that will break right after that lol Thanks 500!
MagicCadillac: Well, that's a pretty job to replace that thank, it takes a little time.
bikermaniac: Hi Ed, I had my expansion tank cracked so I bought a new one on ebay. I
just receive it but it has some ticking and clicking sound inside. I
grabbed the lever indicator stick with my left hand (to avoid it to move)
and with my right hand I tilted the tank and that noise appeared. I checked
with a lantern and it looks like two small metal pieces are loose inside.
Would that be part of the tank? or the tank is just broken or faulty?
Thanks for your help.
EdzGarage: You can replace the upper rad hose without draining the coolant. You will
loose some fluid so you will need to add some after the replacement, and
you may not need to bleed the system. You should bleed anyway to be sure.
Joe Cable: What kind of coolant to use in a 2003 325i e46? Do you have to use blue
EdzGarage: Thanks for the comment and for watching!
