# 3803915 Coolant Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured coolant pump weighing 5.6 kg, superseding 3803434. Volvo's own reman catalogue lists this number as the circulation pump for TAMD63L, TAMD63P, TAMD72 EDC, TAMD72B, TAMD73P-A, TAMD73WJ-A, TAMD74C-A, TAMD74L-A and TAMD74P-A, so match the designation on the engine plate against that list. At 5.6 kg it sits between 3803844 at 4 kg and 3803839 at 8 kg. Reman components are stripped back to the core, rebuilt to a bill of material that carries every design change so the unit meets the current technical specification, tested for performance and then painted to the same finish as new. It is supplied on exchange: core deposit 3806915 is charged alongside it, and the exchange programme lets you send the worn pump back once the new one is fitted and the engine is running again, at which point the core fee is refunded.
