Best Practices

Engine coolant should be changed according to the vehicle manufacturers recommended replacement interval.

To help prevent future issues, we recommend replacing the thermostat when the cooling system has been opened for repairs (e.g. water pump or radiator replacement) or during a system flush.

Before a coolant flush, the entire cooling system should be inspected and repairs made before performing the flush.

It is very important that the correct type of engine coolant is used. Please see your owners manual for the correct type.

Common Symptoms

Dirty or smelly coolant indicates that a system flush may be needed.
