I don't think it's loseing any water before now, but apparently I just found out that the new owner checked the water and opened radiator cap three days ago and now it is loseing water. Ive owned bmws over many years and have never struck this before. It will run fine for days and then bam...square one. It's very frustrating!

Unfortunately, my partner sold it to someone we know, so I can't wipe my hands of it as we deal with them on a regular basis. Thanks for the advice.

Hi, I have a 1996 520i e39 and I just sold it, but it keeps overheating for the new owner. I'll spare the long story, but so far: cleaned the radiator changed the thermostat replaced waterpump checked viscous fan bled it 10000 times replaced and tightened hoses and clamps vacuum pressure tested to get the air out Whats happening now is it will run fine for days, even a week or two, then overheat. Other then that it runs fine normally. It will only overheat when the engine is under pressure, when it idles its fine, if it starts to overheat and you pull over and idle, it goes back to 1/2 way. No water in the oil, it isn't missing etc. All I believe it is still just an air leak somewhere, but this is costing $ and I'd like to know if this has happened to anyone else. I'm at my wits end, every week this car is coming back to me and I feel really bad. Any help would be most appreciated thanks!
