Q: Overheating - 2005 Chevrolet Impala

asked by on

I've done everything but radiator. Could that be it?

Hi there. In most cases, overheating issues are caused by a restriction of coolant flowing through the engine block at some point within the coolant system. The precise component that causes the overheating issue can include the water pump, coolant line damage, thermostat release valve, or the radiator itself. The best thing to do here would be to have a certified professional diagnose the overheating issue firsthand so that this can be repaired without replacing any unnecessary parts.
