1998 Chevrolet Camaro. 85,000 miles. Up until about 50,000 miles, the temperature gauge read a constant 185-190 degrees, in hot or cold, stuck in traffic or on the open road. Since then, once the engine gets warm, if I don't move the car (if I'm stuck in traffic or idling in the driveway), the engine temp climbs rapidly to about 215-220 degrees, when the fan kicks on and cools it back to 195-200. When the fan goes off, back up the temp goes, and on and on. I've never had a car that does this in 30 years, they all stay steady temp once warm, but I'm thinking that constant up and down can't be good for the engine long-term. I've tried: new thermostat, radiator pressure test and coolant flush and fill. Rarely I will get a burning coolant smell, which led me to replace the intake manifold gasket, with no cure of the problem. Yes, I know the fan is doing it's job, but why does it all of a sudden have to? It never did for the first 5 years I had the car. Now I'm extremely hesitant to drive the car when I know I may get really stuck in traffic. So what's causing the rapid temperature rise and lack of airflow through the radiator? Thanks.
have the same problem?
