1989 Acura Integra Repair Question
Temp reading is 30% higher when ac is running and plus the cooling fan is continually running even at start in the morning
It sounds like they are related. Check the wiring from the sending unit to the relay and then the cooling fans. It sounds like there could be an electrical issue there that is showing a false reading to the gauge and keeping the fan on. NOTE: You may want to have the coolant temp checked to make sure how hot it is getting. They make a tool that can check it without opening the radiator. Remember, never open the radiator when the engine is hot.
