My car is a 1997 Chevy Monte Carlo Z34. It's developed this problem where, after 15 minutes of operation, the temperature needle moves from its normal temperature over to overheat, causing the red light to turn on. It stays there for a few seconds, not more than 15-30 sec, then falls back down to normal. It stays normal for a few miinutes, then the cycle repeats again. This happens over an over. I've had the car to the dealer and they've changed out the thermostat and checked the car on their machines and they claim the car is operating at the correct temperature all the time and the fault is in the gauge itself.
I don't understand how this can be true. I'm thinking about putting in an aftermarket temperature gauge and seeing if it verifies what they're saying.
Are there any conditions that can cause this kind of behavior?
have the same problem?
