Parts Desk Insights

Best use case: This is the correct belt for D3 series engines that call for part number 21160912 in the Volvo Penta parts diagram. Note that Volvo Penta has issued a supersession to 24677541 if your parts diagram or dealer lookup returns the newer number, order that one instead. If your engines diagram still shows 21160912, this is the right part.

Common issues: V-ribbed belts on marine diesel engines are often overlooked during annual service. A worn or glazed belt can cause reduced alternator output or seawater pump slippage both of which can lead to charging problems or overheating. Inspect the belt at every haul-out and replace at the first sign of cracking, fraying, or glazing.
