About this part
The water pump on your C4 Picasso B78 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 Citroën C4 Picasso?
Match the exact engine code and the model year of your C4 Picasso B78. 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.
