3801426 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head from the Engine group, weighing 193.68 kg and listed for 2 applications on D-series engines. Volvo Penta supply a reman cylinder head ready for installation with valves and springs fitted, and with the camshaft-bearing housings included where the engine has them. It supersedes part number 3801388, and Volvo Penta specify that the matching head service kit is ordered whenever this head is replaced. In the industrial reman table it is the head listed alongside long block 3801504, unit injector 3801440, turbocharger 3802156 and circulation pump 3803930. It is supplied on an exchange basis: core deposit 3804426 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

• White steam from the exhaust when hot
• Emulsified oil on the dipstick
• Cracking or fire-ring erosion on the gasket face found on strip-down

🛠️ Service Notes

• Do not fit this head without the service kit, which carries the gasket and sealing parts you cannot re-use
