Water Pump Replacement Service and Cost

Best Practices

When replacing the Lexus GS430's water pump, the drive belts and/or timing belt may need to be removed. The belts should be replaced if they show signs of wear or coolant damage.

The entire cooling system—including all the coolant hoses and fittings, radiator, coolant fan(s), and fan clutch (if equipped)—should be inspected when replacing the water pump.

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.

Common Symptoms

Lexus GS430 water pumps require replacement if they begin to leak coolant or become noisy. Leaking water pumps can result in damage to the drive and timing belts.

A failed water pump can be caused by problems in the cooling system, such as a failing thermostat, radiator, or head gasket.
