Q: My vehicle keeps overheating.

asked by on

i changed the my coolant and i added the right amount...i replaced my thermostat cause code p0128 was read on the OBD)...i think my water pump is working properly (if not how can i tell?)...and it still shows overheating on the meter...what could be the issue?

My car has 130000 miles.
My car has an automatic transmission.

Hi there. The overheating condition could be caused by three different things on your vehicle.

  • Plugged Radiator
  • Water pump failure
  • Burned head gasket

The radiator could be plugged up causing the coolant to not flow when the engine is operating. The water pump could have build-up in it and causing it to divert the coolant through the by-pass hose. The head gasket could be burned causing the coolant to go into the cylinder and get burned out with the exhaust. I recommend seeking out a professional, such as one from Your Mechanic, to help you if you cannot determine the cause of your engine overheating.
