Q: Q: Car running hot

asked by on

I just had a water pump put on my car and now the over flow bottle is bubbling and the temperature gauge is going up but my radiator cap is cold so what could be wrong with my car

If the vehicle was not overheating prior to the replacement of the water pump, there are two obvious possibilities: when adding coolant back to the system, all air was not purged from the cooling system; and/or, the water pump doesn’t work. Trapped air is a cause of overheating and if the pump drive belt is not properly tensioned, the pump runs at inadequate speed. Apart from those two possibilities, this failure (that is, the present overheating that perhaps did not exist prior to the repair) could be due to a faulty thermostat, a plugged radiator, a collapsed hose, inadequate coolant level, and so forth. 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 mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

Q: The coolant hose between the radiator and engine is kinked. I think its either the thermostat or the water pump. Please advise how

Q: Motor sounding different after overheating.

Hi, this comes up a lot on this engine. If the coolant level has gone low without an external leaks then you more than likely have a leak in the intake manifold gasket. This would require that the top of...

Q: Thermostat housing small drip/leaking

The thermostat housing if it is leaking and cannot be sealed will need to be replaced. The plastic may be deformed and cannot seal completely.
