    First Time Poster in crisis here, Today on the road my car gave me a coolant level low sign and within minutes told me my engine was overheated. I immediately stopped and had this brought to a repair shop. After discussing on the phone, the mechanic is telling me that due to the design of the...

    A few days ago I replaced my upper coolant hose due to a leak. After replacing the hose, I decided to pour distilled water in the coolant reservoir ( so that I don't just waste any coolant ) just to see if there are any more leaks. I attempted to start the car, but now after it starts, it stays...

    Hello, I was looking over my 03 525iT to get it ready for a drive cycle and smog test after abs module rebuild and noticed a few drops of coolant in the belts area and some coolant on the cooler line. I think it may be the water pump, recently replaced the thermostat and lower radiator hose and...

    Hey guys! I’m trying to get help on how to remove the water pump mounting support. I have a 2017 330i that is leaking right behind the water pump. At first I thought it was the water pump leaking so I replaced it. When I went to add coolant it all started to leak again from the same spot, which...

    1997 e39 528i here with ~230k mi My coolant has been leaking for a while now but never found a place where it could be leaking! I couldn't even find the floor stains with I park it in my garage because as seen in the photos, it seems like it evaporates since it comes to contact with the exhaust...

    I have an 05 330xi that's had constant cooling system troubles. After I overheated back in November and stalled out, I replaced most of the hoses, the expansion tank, the thermostat, and water pump. I keep having persistent leaks dead center. No fluid on the pulleys so it definitely seems to be...

    Hi everyone, I've had a coolant leak in my 2007 335i coupe that so far has resulted in the replacement of: my radiator, then my oil filter housing gasket, and then my water pump this past Tuesday (3/24). Tuesday and Wednesday, I was able to drive probably about 270 miles with absolutely no...
  10. The MINI Board
    I've got a 2011 Mini Cooper base (non-turbo). It's leaking from the o-ring at the back of the waterpump. I put a new, aftermarket pipe in, which lasted about 200 miles. Replaced that with an OEM pipe, which sealed for about 15 minutes. Both times, new O-Rings were used. I've checked the surface...

    Hey everyone, need some help; i know coolant leaks are common on on E39's, done a lot of reading here and i'm still coming up empty. I have 2002 540i M sport 6 gear, 154000 kms (95 miles); car has been going down on a coolant, not a huge amount, about a cup every two weeks. Pressure tested...
  12. X5 E53 (1999 - 2006)
    I recently had an engine overheat on my 2004 X5 4.4 I happened while driving home; I noticed that the air con was not blowing particularly cool air, and after a moment it occurred to me to check the engine temp, which was moving into the red zone. I was fortunately only a couple of minutes...

    Hi, I have a coolant leak for the ages. . . . . When i add coolant to the expansion tank it flows directly to the oil pan so I pulled the water pump (following flow of water). -The head gasket was swapped and torqued to spec: issue not resolved. -Valley pan tube was leaking and was...

    Hello Everyone, I am driving 430d xDrive Gran Coupe (2016) and it's at 32.000 miles. This evening, I received Low Coolant warning, when I checked under the hood the coolant liquid seems actually low, but given the placement of the coolant tank, I can't tell how low it is. I actually took a...
  15. F10 / F11 (2011 - 2016)
    Just bought this monster 10 days ago with 66k miles. I was driving in manual sport + mode shifting from 2nd to 3rd when it rumbled/shook and hesitated and the dreaded "drivetrain malfunction" warning appeared. I limped home, let it sit for about 10 min and restarted and everything was back to...

    I have reviewed several of the coolant-related threads and have not read about this kind of leak! If I missed something, please point me in the right direction. Keep in mind that this car('97 528i) was (foolishly)purchased with 165k and unknown owner/maintenance history. It soon became...

  18. X3 E83 (2004 - 2010)
    Hello, I am taking my 04 x3 to the mechanic in two days to have them check what I think is possibly a failing water pump but I am worried that may not be the problem and don't want them to do it anyway and not solve the actual problem. Am curious if I should just ask them to pressure test it and...
