Engine Cooling problem
1997 Pontiac Transport 6 cyl Two Wheel Drive Automatic 197000 miles
!997 pontiac transport with 3.4 litre, 197000kms, I suspected a stuck thermostat, however the engine coolant slowly diasppears, not much, and I see no leaks at all, nothing in the oil, no smoke in the tail pipes and no odd smells. The engine will heat up almost to the red mark on the temp guage before I get any heat from the heater. I figure there is a leak somewhere but I thought the heating up is a result of a bad thermostat. Was to a garage today and they thought likely the intake manifold and not a thermostat. If it is a intake gasket issue would a leak sealant be a temp fix until I have the 900-1000 to fix it? And would a thermostat replacment help this at all? Once the temperature goes back down the car operates normally with normal temperature though sometimes the low coolant light comes on and off. It has never overheated, never any steam or smoke.
