Frequently asked questions

What should I check when buying a replacement water pump for the BMW R 1150 GS Adventure?

Match the exact engine code and the model year of your R 1150 GS Adventure R21A. 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.
