3803664 Cylinder Head Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head listed as the version with glow plugs for TAD720VE and TAD721VE Tier2 engines - head 3801430 is the same fitment without glow plugs, so establish which the engine has before ordering. It weighs 68.9 kg, covers three D-series applications, D7A-T, D7A-TA and D7C-TA, is listed for engines up to serial number 10705992 and supersedes 3803527. Reman cylinder heads are supplied ready for installation with valves and springs, and camshaft-bearing housings are included where applicable. Reman components are restored to technically new condition, with wear parts and anything outside tolerance replaced by new genuine parts, built to a bill of material carrying all design changes so the unit meets the latest technical specification, then tested and painted before despatch. This is an exchange item: core deposit 3806664 is charged alongside it and refunded as soon as the worn head is returned, and the core can go back once the new one is fitted and the engine is running again.

🔌 Function

Closes the top of the cylinders and carries the valve seats, ports and injector bores, forming the roof of each combustion chamber along with the upper coolant and oil passages.

⚠️ Common Signs of Failure

• Coolant disappearing with no visible external leak
• White smoke or a sweet smell from the exhaust
• Combustion pressure pushing into the cooling system and pressurising the header tank
• Cracks around the valve seats or injector bores found on strip-down
• Head face distorted or corroded beyond the permitted skim

🛠️ Service Notes

• Confirm whether the engine is built with glow plugs - 3801430 is the same head listed without them
• Renew the head gasket, head bolts and single-use seals at the same time, and use lifting gear for a 68.9 kg head
• Core deposit 3806664 is charged with this order and refunded when the worn head goes back - the return can wait until the new one is fitted and the engine is running again
