    Hello, I have a 2000 316i that has a coolant leak from the top of the expansion tank. It was replaced a while ago and ran fine for a while. Now I have the same leak as before. It only leaks after I shut the car off and let it sit overnight. However it sometimes leaks enough to trip the coolant...

    I recently did a full cooling system flush on my '99 328i. (Drained expansion tank, radiator, AND engine block. After draining the old coolant (not sure what it was but prob was the bmw branded coolant. I let it idle and for a little while with only distillled water 3 times and also put some...

    Afternoon guys, I’m already aware of a coolant leak on my 320ci Cabrio - I don’t know where it is but I know it’s there. However my coolant light is staying in after about 3 minutes on every drive. My engine temp doesn’t move from the 12 o clock mark at all either. After checking my coolant...

    Hello. I got a buddy who just bought a 2004 325i. He had some issues with the cooling system. Here's the deal: No leaks No air in the system No signs of blown head/head gasket He said he drove it for about 15 minutes and it got warm. I helped tow it home for him. I think the thermostat is...

    I recently noticed that I have a loud squeal from a cold start on my 2001 330xi. I messed up swapping in a new coolant reservoir and got coolant on my belts, possibly could be related to that. Loud squeal on start but when warm it is way quieter but still there.

    Hello, all. I just recently replaced the hard pipes on my 330i. Unfortunately, a couple of o-rings on the new pipes tore! Went to O'Reilly and while they had a similar size, it was too thick. Fast forward a couple days, my contact at O'Reilly was able to order Mahle o-rings for the exact part...

    Yesterday I filled the coolant after having the car apart for some time and as soon as I turned the ignition on the low coolant level light came on. I believe I bled the coolant system correctly. The thing is that I did it for the first time on my car and some junk came out of the radiator when...

    I have a 2006 325i and i have a very small coolant leak. I cannot seem to find where the leak is coming from, however I have been wondering if anyone has tried using any kind of "stop leak" product. If so, which one has worked for you guys?

    With my luck, once I finally get the coolant system buttoned up, something else goes wrong. Does anyone know what kind of hose this is? Coolant return hose, possibly? Whatever it is, it drips coolant like crazy!

    330ci 2003 Hi all, Couple weeks ago I noticed the low coolant light. I bled the system and topped it up.. probably half a litre. Today I had the same light, expansion tank is almost empty.. havent topped it yet. There is pressure on the rad hoses.. I checked the oil cap and its not...

    So I recently replaced the water pump on my 330i after dinding out the last one was shot, and everything turned out fine. I've been watching it closely and have seen nothing until this last week. When I start the car in the morning, some coolant drips (slowly) near the front of the engine, under...

    I have an '03 330i, and I've bled the cooling system a few times now. Either I'm an idiot, or there's a leak somewhere in the system. I want to rule out any leaks, because I don't see any coolant on the ground and the coolant light doesn't come on. The cooling system is the only trouble I've...

    I just bought my 325i and when i plugged in my scan tool while driving I noticed that my engine was at 99C and my radiator was at 27C. I tried to bleed the system with some distilled water just to see if that was the issue but I don't believe that it is. The radiator stayed stone cold the...

    So for the past month my car has been leaking coolant pretty fast and im currently just refilling as i figure out what to fix. I notice that when my coolant level is low my car starts to smoke and the smoke seems to come from the back of the engine bay on the washer fluid side. The smoke seems...

    We all know the E46 cooling system can be a bit fragile, and overheating from a failure can cause irreversible engine damage. We also know that the gauge in the instrument cluster is not a regular gauge, with the needle pointing unwaveringly to 12 o'clock for the entire 75-115C range. Beyond...

    Hi everyone, what coolant do you all use for e46 M3? My level is a bit low, and while I know I could just top-off with distilled water, I'm looking to get some coolant anyway for the future. Thanks

    Hi all, I’ve got a 2002 M3 but I’m posting in the general forum as the same thing could maybe happen with any model. So the issue. The car has been in storage for a couple of months but I needed it about a fortnight ago. All was good when I put it away and it started and drove fine when I got...

    Hey everyone, I'm new here and finally have a chance to say hi :-) So for starters I have a 2004 325xi with 191K miles on a 5 speed 2.5L L6, and she is starting to hurt. There is a coolant leak, not bad yet, but there's a 2"-3" spot under the center front of where the motor is when I park...

    Hello, I come to you all with a desperate plea. I have absolutely no clue what is wrong with my E46 right now. (2003 325xi) It has no heat in the cabin. I first tried to see if the ac worked, which it did. Then the heater core control valve, which was fine. Flushed the core, and it was...
