Hi folks. My 1998 Z3 2.8 began overheating recently. I shut the car down immediately, waited three hours for it to cool, then drove the .5 mile home. Since then I've gone for a short drive in which it began overheating again. That time I shut the car down for no more than a couple of minutes and turned the key on to check the temp gauge, which had dropped to a nearly-normal range. I drove a couple of miles home with the heater turned on full blast and noticed that no heat was blowing through the vents.
The car has sat since then and I am now getting ready to do some work on it. I am guessing the water pump has failed, but would appreciate feedback about possible explanations for this overheating and parts sources.
Additional info: I've owned the car for the past two years and do not know what has been done to the cooling system previously. It has nearly 250,000 miles on it, so there's obviously been updates/maintenance at some point.
