About this part
The water pump on your 403 circulates coolant between the engine and radiator. A failing pump causes overheating, leaks and in severe cases engine damage – timely replacement is essential.
Frequently asked questions
What should I check when buying a replacement water pump for the Peugeot 403?
Match the exact engine code and the model year of your 403. Check whether the gasket and thermostat housing are included, as these are commonly replaced together.
Should I replace the timing belt and water pump together?
If the timing belt drives the water pump, yes. The labour to access both overlaps significantly, making it far more cost-effective to replace them at the same time.
