Porsche Water / Coolant Pumps
Your Porsche cooling system's pumping function is handled by its water pump, which keeps the coolant mixture moving. The main water pump is gear- or belt-driven but, in many cars, a secondary electric water pump is used for improved flow and cooling. Critical to the pump's operation is the drive belt that turns it. On most newer cars this is the engine's timing belt. On older cars, the pump and belt are external and run off the main crankshaft pulley with a "V" or flat belt. Maintenance of cooling system pumping is limited to scheduled coolant replacement and drive-belt replacement and tension adjustment (external type). Timing-belt-driven pumps should always be replaced at the same time as the timing belt and tensioner.
