      Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)

      Restore your vehicle's cooling system to proper working order, and minimize the risk of premature failure, by installing a Bosch Auxiliary Water Pump. Bosch Auxiliary Water Pumps are designed to operate in the highly-stressful environment of today's cooling systems. Eliminating the mechanical commutation system leaves the durability of the rotor bearings as practically the only limiting factor for service life. In addition to that, the lower number of moving parts results in significantly reduced noise.

      Product Features:

      • OE Quality, reliability and service life
      • Leak-proof sealing of the drive
      • Fuel savings and reduced emissions
      • Cooling even without operation of the engine
      • CO²-reduction by optimized efficiency, speed control and reduced weight
      • Coverage of a wide hydraulic performance range
      • Reduced noise level
