BMW Water Pumps for BMW 3 Series E46 (1999-2005)

Clear BMW chassis
When maintained, your BMW's cooling system should be bulletproof. The weakest link on any BMW model is likely to be the water pump, thermostat, or electrical parts on the newer models. BMW water pumps have gone through many design and material changes over the years in an effort to make the cooling system more efficient and reduce parasitic drag on the engine. The water pumps we sell are the latest and best designs that BMW and OEM suppliers can produce. Whenever possible we prefer to sell a water pump with a composite impeller, not metal. The latest BMW designs use a composite impeller that is far lighter than metal and much stronger than plastic. Metal impeller pumps are typically heavier and may have bearing problems that lead to premature leaks. Plastic pumps were infamous in the mid-1990s for disintegrating. The composite impellers have proven themselves for over a decade as a trouble-free and efficient design and many of the OEM suppliers are also introducing updated composite designs for older models too.
