3839414 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta cylinder head from the Engine group, weighing 232 kg and listed for one application on a D series engine. It supersedes part number 3830742. At 232 kg this is a crane lift, not a manual one, and the published weight is high enough that it should be checked against the head being replaced before ordering.

🚤 Compatibility

Typically suits:

• Volvo Penta D12C-A MP

• Engine Family: D

⚙️ Key Features

• Supersedes 3830742
• 232 kg — mechanical lifting equipment essential
• One listed D series application
• Engine group major component

🔌 Function

Closes the top of the cylinders and carries the valve gear, ports and injector seats, containing combustion pressure while passing coolant and gas through its passages.

⚠️ Common Signs of Failure

• Coolant loss with no external leak, or bubbling in the expansion tank
• White smoke or a sweet smell from the exhaust
• Compression down on one or more cylinders
• Oil and coolant mixing
• Cracking or corrosion found around the valve seats or injector bores

🛠️ Service Notes

• Plan a hoist and a spreader or lifting eyes before starting — 232 kg cannot be handled by hand
• Check the block face for flatness and cleanliness, and renew the head gasket, head bolts and all disturbed seals
• Confirm the quoted 232 kg against the head being replaced, as the figure suggests a very large assembly
