Car overheating when Idle
My Mazda 6 started overheating during a heavy traffic day. Ever since, I noticed it would only start over heating only when the car is idle at a light, traffic, or parked for about 5 minutes and then slowly start creeping up. If I give it some rpm, the gauge comes back to normal reading. *Additional info - Heater only works when riding - I have to add a bit of coolant everyday - Changed thermostat, fan control module and fans work well. My suspicion is the water pump has gone bad. Help!!
