In the case of the MINI Cooper S, the water pump is driven off the end of the supercharger. This setup is a bit different than most cars where the water pump is driven off the engine belts. When a water pump begins to fail, you’ll notice that the car tends to overheat at low engine speed, such as sitting at a stoplight. When you accelerate, the engine temperature will drop. Now, this is not always indicative of a water pump, but a good starting point.
