Question about 1994 Oldsmobile Cutlass Ciera
I have a 1993 cutlass Cierra with a 6 cyl. 3.1 engine. It overheats after 5- 10 min . The radiator and hoses are not hot. Thermostat right? Wrong! I have tried 2 new thermosats and still overheats. I thought some kind of airlock, so I used the air bleeder on the Tstat housing. Still no good. Could it be a bad Water pump? Does anybody know if these are particularly suseptable to corrosion problems? I wondered if the impeller is shot? I am about to try leaving the stat out?
Does there seem to be alot of pressure on hoses, when you squeeze them ? ive seen impellars on the water pump cause this, but not very often. a possible air lock can be a pain. a trick is to jack front end of car up to a point engine is tilted back a bit. it helps the bubble in finding its way out. if this dosent work after a couple tries, id start to suspect headgasket issue allowing air into coolant. a tell tale of a head gasket would be a constant temp gauge fluxuation ( mid temp-hot mid to hot etc. ) let me know.

Try the bleed hole on top of water pump.Ive had this happen on new water pump installation.

The water pump is your only option. Its not getting any cerculation.
