Q: Car over heats even though I have coolant in the engine

asked by on

My car seems to over heat whil idle with the actual on

The most common cause is the cooling fan is not coming on or there is a restriction in the airflow across the radiator. You should have this checked first then see if the radiator is flowing coolant through all the passages. This can be checked with a laser type temperature gauge. If low flow then replace radiator and thermostat. If the radiator is not showing coolant flow at idle but does at higher rpm then your water pump and thermostat needs replaced. If you would like, a certified technician from YourMechanic can come to your home or office to replace these parts.
