On highway the coolant temperature seems fine with or without A/C on. But after that when I get off the highway onto the side streets around my house the coolant temperature gos up. More so with A/C off. Bought car with 20000 miles and never done this before. I have flushed the coolant system, replaced thermostat, water pump and coolant temp sensor.
