As those numbers on your BMW’s odometer increase, certain parts are will wear out and need replacement. BMW 645 parts in this category include the alternator, the starter and the water pump, all of which will probably need be switched out with new BMW parts at least once in 100,000 miles. The water pump is literally the "heart" of the cooling system. These BMW 645 parts are the ones that keep the engine's operating temperature within the optimal range. With thousands of tiny, but powerful explosions taking place inside the cylinders every minute, temperatures can get up to the melting point of lead. The metals from which many BMW 645 are made do a very efficient job at conducting heat, and that temperature can rise very quickly. The water pump circulates water through passages inside the engine block, which are called "water jackets." This is what keeps that heat under control; coolant absorbs excess heat and carries to the radiator where it is literally "radiated" to the exterior of the vehicle with hundreds of tiny cooling fins. If any of the BMW parts making up the cooling system should fail, the engine will overheat, and warped cylinder heads, burnt valves, or a even a cracked engine block can be the unfortunate result. The cooling system should be inspected periodically. If water is dripping from the water pump and the drive shaft seems loose, it’s time for a new one. When shopping for discount BMW 645 parts, make sure used or rebuilt compnents are certified.
