Loppy

Hi all car overheated yesterday didn't quite get to the red as the dash warning sounded early luckily and i pulled over and let it cool .It is now intermittently loosing coolant out of the top of the expansion tank around the radiator cap at the top from what looks like the pressure release in the cap .could this be a faulty cap and expansion tank or something more sinister? .Also the hose does not seem to have alot of pressure going into the radiator from the engine and is relatively hot although after it cooled the car has not overheated .it drove at normal operating tempreture on the way home and idling in the driveway whilst trying to find the issue .It is only leaking when at operating temperature which is bang at 12 oclock on the dial. Any help would be appreciated. the car in question is a 2001 525i with a m54 if that helps.

mine did the exact same thing except it got to the point were it wouldn't idle as it wasn't putting out enough pressure .Turns out a really common fault on these but caught me off guard as my last one just died completely on my e36. I think the pump was $250 including gst so not a expensive fix and literally takes like 30 minutes.

cheers i love your model of the 7 series if i could justify having one i would get one in a hearbeat.

yeah the fuel pump went about 3 weeks after i got it but i haven't got a code reader yet and it had only 1/2 died so wasnt sure what had happened ,but hopefully should be able to fix most things myself from now on.next on the list is the 1/2 shaft on the back right :/ and a full fluid change.Ideally i was looking for a 530 or 330 but after viewing and driving over 10 this one was the best and i don't really notice the loss in power, and i agree with you on how well they drive considering the size and style differences to my 328 coupe this thing still handles a dream.

Hey guys/girls Just a quick intro I've been on the American forums back when I had my e36 coupe now I've finally come back to my senses and bought another bm this time a e39 525i .will be flicking in here quite abit while I work on getting her back up to a standard I'm happy with . Cheers
