If the car is overheating without a thermostat and the water pump is new and being driven at sufficient speed, you might have a blockage, such as in the radiator. Other causes of overheating include low coolant level (including that due to leaks), a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans. Certain engine faults, such as a leaking head gasket, poor engine running condition or exhaust blockages can also cause overheating. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
