Every product page below carries its own compatibility list — always check it against your engine designation and serial number. ### What an AD31 Service Uses An annual engine service normally comes down to the same handful of consumables. For the AD31, all of them can be pulled straight from the genuine catalogue: - **Oil filter** — the genuine oil filter catalogued against the AD31 range here is [3517857](https://www.sawleysautoandmarine.com.au/products/3517857-oil-filter-genuine-volvo-penta); check the compatibility list on the product page against your model. - **Fuel filters** — Genuine fuel filters and water separators carrying a fitment tag for this engine are listed in the [filtered collection](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-filters?filter.p.m.custom.engine_series=AD31); match the part against your engine designation and serial number. - **Air filter** — Genuine air filters carrying a fitment tag for this engine are listed in the [filtered collection](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-filters?filter.p.m.custom.engine_series=AD31); match the part against your engine designation and serial number. - **Water pump impeller** — the genuine impeller catalogued against this engine is [3583087](https://www.sawleysautoandmarine.com.au/products/3583087-impeller-genuine-volvo-penta); check the compatibility list on the product page before ordering. - **Drive belts** — Genuine drive belts and tensioners carrying a fitment tag for this engine are listed in the [filtered collection](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-belts-pulleys-tensioners?filter.p.m.custom.engine_series=AD31); match the part against your engine designation and serial number. - **Thermostat** — Genuine thermostats and cooling-system spares carrying a fitment tag for this engine are listed in the [filtered collection](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-cooling-system?filter.p.m.custom.engine_series=AD31); match the part against your engine designation and serial number. - **Gaskets & seals** — Genuine gaskets, O-rings and seals carrying a fitment tag for this engine are listed in the [filtered collection](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-gaskets-seals?filter.p.m.custom.engine_series=AD31); match the part against your engine designation and serial number. - **Engine oil & coolant** — genuine oils and coolant are listed under [Oils & Chemicals](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-oils-chemicals); always confirm the grade against your engine manual. Volvo’s maintenance catalogue groups the 31-series lists under MD31, TMD31, TAMD31, AQAD31 and KAD32 — the [TAMD31 page](https://www.sawleysautoandmarine.com.au/pages/volvo-penta-tamd31-service-parts) reproduces that list. The AD31 shares the family’s ancestry, but its headers do not name the AD31 outright, so confirm any part from that list against your engine serial number. Beyond the service list, every AD31-tagged part on the site can be browsed by category: [Filters](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-filters?filter.p.m.custom.engine_series=AD31), [Service & Repair Kits](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-service-repair-kits?filter.p.m.custom.engine_series=AD31), [Belts & Tensioners](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-belts-pulleys-tensioners?filter.p.m.custom.engine_series=AD31) and [Gaskets & Seals](https://www.sawleysautoandmarine.com.au/collections/volvo-penta-gaskets-seals?filter.p.m.custom.engine_series=AD31), each narrowed to the engine family. ### AD31 Service Parts, Pictured - [![Genuine Volvo Penta Oil Filter 3517857](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_3df76804-2c98-47fd-b126-382bc6f005c8.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/3517857-oil-filter-genuine-volvo-penta) Oil Filter 3517857 - [![Genuine Volvo Penta Fuel Filter Insert 1147147](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_130dce25-3a8b-4cc5-a645-e09426d2fef8.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/1147147-fuel-filter-insert-genuine-volvo-penta) Fuel Filter Insert 1147147 - [![Genuine Volvo Penta Fuel Filter Insert 3581760](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_c9a34a72-796b-47f1-91d6-fb67f1ed240c.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/3581760-fuel-filter-insert-genuine-volvo-penta) Fuel Filter Insert 3581760 - [![Genuine Volvo Penta Fuel Filter 840531](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_5efed0cb-20aa-4747-b381-81e6a7c36d30.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/840531-fuel-filter-genuine-volvo-penta) Fuel Filter 840531 - [![Genuine Volvo Penta Air Filter Insert 21646645](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_0e747468-3684-48e8-a7e5-01b797d03fad.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/21646645-air-filter-insert-genuine-volvo-penta) Air Filter Insert 21646645 - [![Genuine Volvo Penta Air Filter 21782391](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_fbe174aa-67b9-49aa-ba9d-3297f78bb298.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/21782391-air-filter-genuine-volvo-penta) Air Filter 21782391 - [![Genuine Volvo Penta Air Filter Kit 22004848](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_d45366cf-3f51-4828-bd11-6a6816a99efa.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/22004848-air-filter-kit-genuine-volvo-penta) Air Filter Kit 22004848 - [![Genuine Volvo Penta Air Filter Insert 858488](https://cdn.shopify.com/s/files/1/0994/8115/7924/files/original_4d5dec96-2994-43ba-be5b-3446b320d2e7.jpg?width=400)](https://www.sawleysautoandmarine.com.au/products/858488-air-filter-insert-genuine-volvo-penta) Air Filter Insert 858488 ### Not Sure Which Part Fits? Parts differ within a family by model, build year and specification — two engines with the same designation on the rocker cover can take different filters or impellers depending on serial number. Check the compatibility list on each product page against your engine plate before ordering, or call us on **[0412 532 984](tel:+61412532984)** with the serial number and we will confirm the right parts for your engine.
