Question about 1991 Chevrolet Caprice

Open Question

I have a 91 chevy caprice v8 305. My interior temperture gauge has been bouncing up and down for like 2 weeks now. 2 days ago my heat control valve broke. (The line going from engine into thhe valve busted off). My car usually has a heater that almost runs you out :) . I replaced the valve now the gauge goes from cold to orange hot in less than 2 minutes. The new valve is leaking,there is no vacuum to valve and getting false temp reading. Could this be electrical?

SOURCE: 97 f 150 runs hot for minutes then runs ok

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

SOURCE: Chevy Venture Overheating

Almost sounds like the same symptons as my van. Turns out the guage was not the problem. The van was in fact running hot because the electric radiator fans were not kicking in when the engine was hot. I replaced the relay switches for the fans. There are two of these in the fuse panel under the hood. There has been no problem with overheating since

SOURCE: temp gauge bouncing up an down

i would say if the fluid is full and the thermostat is not sticking it would be your engine coolant temperature sensor (ect) sensor

Bad water pump. The seals are more than likely shot. Usually at higher rpm the temp goes down and at idle it would overheat. Had a friend with the same problem.

The heater put out very little heat. also the temperture gauge moves very little. is this a bad thermostat. or could it be a bad heat control value.


If the Temperature gauge is moving less than before, its your Thermostat. If the Engine Temperature is the same, then your heat control valve is not opening or a duct flap(called a door) is not moving under the dash.

Having a Bad thermostat will affect how controls on the engine work and when they work.

My 93 chevy caprice has new water pump and themostat but temp gauge still indicates its still running hot.


Could possibly have a clogged radiator, Which engine does your caprice have? You also need to make sure all air is purged from the system.

When does it over heat, all the time, or just when idling?

Temperture gauge


It's either a loose wire on the sending unit, or the sender itself. Or i suppose it could even be the gauge, but i'd bet on the one of the other 2.

Temperture gauge show's hot after a one minutes running


Most likely the heat sensor.
Ensure you replace the gauge sensor with the correct type to suit your gauge.
(dont confused it with the overtemp alarm switch sensor).
Check you've got the right sensor by shorting it out to frame/ground and observing the gauge movement.
