Ok. The overheating is an intermittent problem. I may make 2-3 trips (5-10 miles) and no overheating. Then, I may make a 1-2 mile trip and it overheats. To make it even weirder, if I turn on the heater the temperature drops from med-high to COOL in about 3-5 seconds.
I have replaced the thermostat, the water pump is new when I replaced timing belt less than 5,000 miles ago.
No evidence of coolant in oil, no smell of coolant in the exhaust. Car runs beautiful, just HOT intermittently.
Coolant appears to be flowing properly thru the radiator.
Ideas? Thoughts? I appreciate ANY and all help.
