Oil Change – Volvo Penta Marine Diesel Kad42 Kad43 Kad44 Kad300
Oil Change Guide for Volvo Penta KAD3-00
Tools Needed
- Oil extraction pump with pipe
- Oil filter pliers (oil pump pliers)
- Strong plastic bag (e.g., rubble sack or clear carrier bag)
- New oil filter (VOP 43135 for CAD 44, check compatibility for other models)
- Engine oil (Volvo Penta VDS3 15W40 recommended)
Safety
- Ensure engines are warm before starting the process to facilitate oil flow.
- Be cautious when handling hot engine parts and oil.
Steps
- Warm up the engine by running it in gear or taking a short drive until it reaches around 85-90°C.
- Remove the dipstick from the engine.
- Insert the extraction pump pipe through the dipstick hole until it reaches the bottom of the oil pan.
- Activate the oil extraction pump, pumping it up and down a few times to create suction and start draining the oil.
- Once most of the oil is out, remove the pipe and reposition it to drain any remaining oil.
- Loosen the oil filter using oil filter pliers by turning it anti-clockwise until it can be removed by hand.
- Place a strong plastic bag around the oil filter to catch any dripping oil, then unscrew the filter by hand and let it drop into the bag.
- Wipe the oil filter housing and check that the rubber seal has come off with the old filter.
- Fill the new oil filter with engine oil and apply a small amount of oil around the filter's sealing surface.
- Screw on the new oil filter by hand, turning it clockwise until it is finger-tight or hand-tight.
- Refill the engine with engine oil using the dipstick to monitor the level, adding about 9 liters (or 3/4 of a can) in total for the KAD3-00 engines.
Tips
- Use a clear plastic bag to easily see any leaks or drips.
- Ensure the new oil filter is compatible with your specific engine model before purchasing.

Frequently asked questions
What oil filter fits a Volvo Penta KAD43?
The Volvo Penta KAD43 uses the oil filter sold as 18-7926, plus its OEM and aftermarket cross-references (1 compatible numbers are listed above). Confirm the number against your engine's model code and year plate before ordering.
How often should I replace the oil filter on a Volvo Penta KAD43?
Change the oil and filter every 100 running hours or once a season, whichever comes first (check your manual for the exact interval).
What else do I need for an oil change on a Volvo Penta KAD43?
The correct grade and amount of engine oil (see the manual or the video), a new drain-plug washer, a filter wrench and a drain pan or oil extractor pump. Nothing exotic — it is standard service equipment.
What are the signs the oil is overdue on a Volvo Penta KAD43?
Dark, gritty oil well past its interval, low-pressure warnings — and milky or grey oil, which means water is getting in and should be investigated immediately.
How long does an oil change take on a Volvo Penta KAD43?
About an hour for a competent DIYer. Run the engine warm first — warm oil drains faster and carries more contaminants out with it.
