Need help asap 1998 honda civic dx cooling fan turns on right when I start the car noticed it when I purchased the vehicle couple weeks ago. And second problem is when I turn on ac compressor stay on for like 2min and then shuts off but turns on when I hit the throttle pedal. And 3rd problem is the temp gauge doesn't move. Today I just swapped the cylinder head put new head gasket,timing belt,water pump and tensioner pulley old cylinder head had 3 badly cracked valves on cylinder no.2and3. Once again notice the temp gauge not moving when first purchased the car.
