'94 Camaro cooling problem

First, water pump is OK, and I can find no leaks....

When I head out for work in the morning, the temp gauge climbs into the upper temp range. Most of the time, after about 15-20 minutes of driving, it will drop back to the "normal" position and may or may not go back up. Same thing on the way home later in the day, but temp stays high (about 3/4 of the way up on the gauge).

Coolant level is OK, and the fan is working. Could this be an intermittent thermostat problem? I thought thermostats either work or don't work. Any advice appreciated...thanks!

I had the same problem with My 92 Camaro RS I switched out the Thermostat with a 160 degree instead of the 185 degree and had the Radiator flushed. Since then no problems.

I think your and the OP's problems are similar. Partially gunked up radiator...

Now that you've fixed the radiator, you might want to put the warmer thermostat back in....keeps engine wear down to a reasonable level. Not to mention the heater works better.

I was waiting until colder weather, after the flush I used the 185 for about a week and it kept running at around 220-240 with the 160 thermostat it ran around 190

sounds like there's something wrong with the cooling system...if it's working properly, the engine should be running just a shade over the thermostat opening temp. Are these new thermostats? they do get weak after many years of service.
