1997 Pontiac Transport 161,000 miles plus
I took the van to a mechanic. He tod me the fans were okay. He said he fixed something called a relay. I was on the road back home when the van started overheating again. The temperature gauge flucuated from one extreme to the other. The needle would climb to 210 degrees, then back down below 210, then back over 210. I can feel something slip as I accelerate. Could that be a belt or is there something internal (drivetrain, transmission) that is causing the engine to overheat?
Loss of coolant - no
Loss of system pressure - don't know
Low coolant protection - don't know
Incorrect belt tension - maybe
Timing retarded by malfunctioning PCM - maybe
Radiator fins obstructed - don't think so. Radiator is new
Cooling system passges blocked by rust or scale- maybe
Reservoir hose pinched - no
Cooling fans inop - don't think so. Fans spin at a high rate of speed when engine is running. Slow down after the engine is turned off and spin slowly, eventually stopping
Loose or damaged deflector - don't know
Thermostat stuck in closed position - don't know
Faulty water pump - don't know
Incorrect radiator - no
I am going to give my mechanic a list of the items listed above that I am not sure about.
Your thoughts? Thanks much.
