Febi Bilstein Auxiliary Water Pump (184631) Fits: Mercedes

This Febi Bilstein Auxiliary Water Pump (184631) is supplied in OE matching quality and maintains the high standards of Febi Bilstein products.

An auxiliary water pump is different to a single water pump because it is instead an electrically controlled motor with the main role of circulating water using a bypass hose from the main coolant lines to the heater core.

Auxiliary water pumps allow engines to operate with greater efficiency because they generate less excess heat and oil consumption. A key benefit of an auxiliary water pump is that it's great for improving passenger comfort as it can provide the necessary heating even when driving in busy traffic or at a low RPM (Revolutions Per Minute).

All Febi Bilstein components are developed and manufactured to meet OE specifications to be direct replacements and undergo rigorous testing and quality checks to guarantee every part is manufactured to a high standard. You can enjoy added peace of mind with a 3-year manufacturer's guarantee for every product.
