New to this BMW thing....Already having problems
Just bought a 98 528i on Wednesday. The car looks and drives great, and is really clean. 98K miles. I was really excited when I got the car, but today, I ran to the store about two miles away, and on the way back I was stopped because the bridge was up. While sitting, I heard a pressure release whoosh and steam started billowing from under the hood. The temp gauge was all the way in the red.
I pulled over into a parking lot and shut the engine off. Coolant was all over the front end of the car, as well as the engine bay once I had the hood up. Looking things over, I saw the top radiator hose had blown off the radiator, but looked fine. After I waited for a bit, the temp gauge returned to normal, I reattached the hose and figured I could make it the last mile home if I babied it.
I made it about half a mile before I noticed the temp gauge rising again, and I made my way towards the nearest parking lot, with the hose blowing as I pulled into the lot. Again, I waited a bit, reattached the hose, and barely made it home before the gauge was rising yet again.
I've read nearly every forum post on here about this issue, and I'm somewhat on the fence about what to do. From what I've read, this could be a thermostat issue, a water pump issue, or even a clogged radiator. I really don't have the money/desire to take this to a shop. My question is, would I be best served by going ahead and just doing the following:
Top Radiator hose
Should I just go ahead and do all of it and hope that one of them was the issue? Or should I maybe go with the WP and thermostat first seeing as they are cheaper and see how that goes?
Also, I've been thinking that maybe, just maybe, the hose just slipped off (not very realistic, I know) but would it be a good idea to just reattach everything and flush the coolant and see if that works?
The clamp that attaches the hose to the radiator doesn't seem to attach it that well. Even when I tighten it down, I can still slip the hose off pretty easily by hand. Is this normal?
Thanks a lot for all of the advice, I don't really have any friends with solid BMW knowledge.
