This is on my sisters 95 325i Automatic with 120k roughly. About a year ago or so, the car was overheating. We replaced the tstat and housing to a metal one. Car ran fine ever since.
The last couple of days, my sister called me and told me the car was overheating again. It's overheating when driving and not just idling and it happened today when it's like mid 60s out while on the move. So I finally get a chance to check it out and I find that there is coolant splattered through areas of the engine bay including on top of the altanator, oil filter housing. It's not a ton of coolant by any means, however. The heater blowing maybe "luke" warm air at best. I checked the system for leaks and no "air" or "hissing" came from the bleeder. I checked the tstat housing for leaks and could not find any. Coolant is clean of oil, dipstick is clean of anything milky looking as is oil cap. I have NOT flushed the oil yet.
Now I have no idea what waterpump is in her car. Could still have the plastic one for all I know :dunno So my gut feeling is telling me that the waterpump is starting to go and a seal is or something is splattering.
So my plan of action is to replace waterpump with a metal one, gasket of course, seprintine belt, AC belt (it's getting old), change upper and lower radiator hoses, flush coolant and add waterwetter (she has fan delete already), change oil.
My only concern is, should I be worried that the tstat itself died because of the overheating issue? :help
Any other suggestions or input are much appreciated.
