3801343 Circulation Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured circulation pump for the D2-40, D2-40B, D2-40F, D1-30, D1-30B and D1-30F, weighing 1.089 kg across six applications. It is the lighter of the two D1 and D2 circulation pumps listed here: 3801345 at 1.451 kg covers a different and wider set of twelve D2-55, D2-75, D2-50F and D2-60F applications, so the two are not alternatives to each other. Volvo Penta rebuilds these to the current bill of material with new genuine wear parts, then tests and paints them. Supplied on exchange, so a core fee is added to the invoice and refunded when the worn pump is returned.

🔌 Function

Circulates coolant through the block, head and heat exchanger so heat is carried away from the combustion chambers at a controlled rate.

⚠️ Common Signs of Failure

• Coolant staining or dried residue below the pump body
• A whine or growl from the pump bearing that follows engine speed
• Coolant temperature climbing under load
• Wobble or roughness felt at the pulley when turned by hand
• Impeller vanes found eroded or corroded on strip-down

🛠️ Service Notes

• Only 362 grams separate this from 3801345, so confirm which pump your engine takes rather than judging by size
• Renew the drive belt and check the tensioner and thermostat while the front of the engine is open
• Core deposit 3804343 carries the exchange fee and is refunded when the old pump goes back
