About this part
The water pump on your Sportster S RH1250S 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 Harley-Davidson Sportster S?
Match the exact engine code and the model year of your Sportster S RH1250S. 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.
