The BMW Series 750iL may indeed be the "ultimate driving machine," but any mechanical device, it is subject to wear and tear, requiring periodic maintenance. As the odometer racks up miles, certain components of the BMW Series 750iL will experience normal wear, requiring replacement. Typically, these include the alternator, the starter and the water pump, all of which will likely be replaced once in 100,000 miles.

The BMW Series 750iL water pump is vital to maintaining your engine's optimum operating temperature. Inside the cylinders, thousands of small explosions take place every minute as the spark plugs ignite the fuel-air mixture injected into the cylinders.

This creates intense heat. Since the metals making up most of the BMW Series 750iL engine's components are excellent conductors, temperatures rise to extreme levels. This temperature is kept in check by circulation of water from the radiator. The water runs through passages in the engine, called "water jackets," and carries off excess heat to the radiator where it dissipates. The BMW Series 750iL cooling system consists of water, water jackets, the cooling fan, the radiator, the connecting hoses and the water pump. Should any of these fail, warped cylinder heads, burnt valves, a cracked engine block, or a total seize-up could result. The cooling system should be inspected for leaks periodically. If you see water dripping from the BMW Series 750iL water pump, it does not necessarily mean that it needs to be replaced - it may simply need a new gasket.If your BMW Series 750iL water pump has become defective, however, you can count on us for a genuine factory-authorized replacement at a steep discount price.
