What are the possible causes and remedies?


I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.

the most likely cause is a faulty water pump

other possible causes would be a faulty thermostat, faulty fan, blockage / airlock in the cooling system or blown head gasket

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
