The seawater pump circulates raw water through the engine’s heat exchanger to keep the engine at operating temperature. Because this belt drives the cooling pump directly, a failed or slipping belt will interrupt raw-water circulation and can lead to rapid engine overheating.\u003c\/p\u003e\n\u003cp\u003eThis is the seawater pump belt specifically — not the alternator belt or power-steering belt.

If a customer is unsure which belt they need, the belt specification (4PK935) and the seawater-pump diagram position are the most reliable identifiers. Also worth noting: when replacing this belt, it’s good practice to inspect the seawater pump impeller at the same time — both are wear items that often reach end-of-life together on D3 engines.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563997331492,"sku":"24677541","price":56.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/c1beae75-a898-48e4-81ed-37c29b38f19c.png?v=1773092396","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-d3-seawater-pump-belt-24677541","provider":"Marisol Marine Company","version":"1.0","type":"link"}
