3812109 Cylinder Head Gasket | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta cylinder head gasket, 1.20 mm thick, from the Engine group, weighing 0.084 kg and listed for 3 applications on D series engines. Gasket 3812199 is also 1.20 mm thick but is listed for the D1-30F at 0.088 kg, so thickness alone will not separate the two.

• Engine Family: D
• HP Range: 20 HP

🔌 Function

Seals the joint between cylinder head and block, containing combustion pressure and keeping coolant and oil out of the cylinders.

⚠️ Common Signs of Failure

• White steam from the exhaust with coolant loss and no external leak
• Bubbling or pressure building in the header tank
• Oil in the coolant, or coolant in the oil
• Loss of compression on one cylinder and rough running
• Blown witness marks or corrosion tracks between cylinders on strip-down

🛠️ Service Notes

• Gasket thickness is part of the specification, so fit the 1.20 mm gasket only where 1.20 mm is called for
• Check the head and block faces for flatness, and renew the head bolts if they are the stretch type
• Order by part number, as 3812199 shares the same 1.20 mm thickness
