3803844 Coolant Pump Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured coolant pump for the D9A2A, D9A2B and D9A2C, weighing 4.032 kg. Volvo Penta's reman catalogue lists it against the D9-MG marked For HE/KC - 3803930 at 3.692 kg is the For RC pump in the same table - and again for the D9-MH and D9-425 up to serial number 1009163095. For engines from serial number 1009163096 onwards the catalogue shows no reman circulation pump against those two models, so the build date matters as much as the model here. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn pump is returned.
