Hello. I have a 2000 ford focus zx3. The temperature gauge goes past the half way mark when I'm in traffic or when I idle for to long. I checked out your video and did the following. The radiator is new and there is no leaks. The thermostat and housing are new, the fans turn on and I even changed out the relays and put a new temperature sensor and no head gasket leak. The only way I can get the the temperature gauge to go back to the middle is when I turn on the AC or heater which then kicks in the fans and the car goes back to normal. Please advise. Thank you for your time.
live with that, old age just makes em run a bit warm, or just turn on the ac to turn the fans on.
