3801964 Coolant Pump Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured coolant pump from the Cooling System group, weighing 5.272 kg and listed for one application in the TWD series. It supersedes part number 3801909. Coolant pump 3801976 is published at 5.882 kg for the TAD series, so 0.61 kg and the engine series are all that separate them. This unit is supplied on an exchange basis: core deposit 3804964 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
