Volvo Penta D4 & D6 parts

Volvo Penta D4 and D6 are the latest in-house-built marine diesel engines, designed to replace their predecessors D31, D32, D41, D42, D43, D44 & D300. Like the previous generation, this engine family was developed with the scope of marine use.

Introduced in 2003, they feature common rail fuel injection and advanced electronics like EVC (Electronic Vessel Control). The 4 valves per cylinder, driven by twin camshafts, achieve improved fuel efficiency and meet the stricter Tier 3 emission standards.

Volvo redesigned the engines in 2019 in order to increase their power output and fuel efficiency while making their maintenance easier. The engines can be installed as inboards, with sterndrives (DPH & DPR), or with IPS pods, thus offering great versatility among catamarans, speedboats, and yachts. The earliest D4 engines had 145HP, while the latest models feature an astonishing 320HP, all coming out of 4 cylinders with a total capacity of 3.7L and the assistance of a turbocharger. Its six-cylinder counterpart almost hits the 500HP mark and has an engine capacity of 5.5L.

Frequently Asked Questions About Volvo Penta D4 & D6 Marine Diesel Parts:

Why is my Volvo Penta D4/D6 overheating?

Volvo Penta D4 & D6 have an indirect cooling system, which means that the seawater pump is indirectly cooling fluid through the heat exchanger. If your engine is overheating, it is recommended to check all the cooling components until you find the reason. The easiest thing to check is the seawater pump and the seawater filter for possible blockage or debris, or for an impeller due for a change. Next, you move on to your heat exchanger and your oil cooler. If there are accumulated depositions, it is time to clean your cooler.
How often to change the oil on a Volvo Penta D4/D6?

Volvo Penta D4 and D6 are high-performance engines that operate on higher RPM (2750–3250), compared to other diesel engines; thus, you should do your maintenance schedule every 200 hours or every year, whichever comes first. Failing to do so can lead to serious problems, like sludge accumulation on the main/big-end bearings, which can lead to increased friction, overheating, and engine seizure.
What is the oil capacity of a Volvo Penta D4?

The Volvo Penta D4 needs 12.5L engine oil, including the primary and the bypass filter.
What is the oil capacity of a Volvo Penta D6?

The Volvo Penta D6 needs 20.0L engine oil, including the primary and the bypass filter.
What kind of oil is needed for the Volvo Penta D4/D6?

Both of them need synthetic oil 15W40 that fulfills the VDS 4.5 specification.
I am replacing the main and the big-end bearings of my Volvo Penta D4/D6. Do I need new bolts?

These bolts are stretch bolts, which means that they can be used only once. For the big-end bearing caps, refer to part number 3581905 and for the main bearing caps, check part number 3581876.
What are the torque settings for the Volvo Penta D4/D6 main rod and big-end bearings?

The main bearing caps need to be tightened at 130 Nm, then an additional 180°.
The big-end bearings (rod bearings) must be tightened 65 Nm on the first stage, then an additional 90°.
What are the tightening torque settings for the Volvo Penta D4/D6 cylinder head?

The cylinder head bolts of the D4 & D6 engines are tightened in 5 stages, according to the workshop manual. The
