3803033 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head, weighing 34.533 kg and listed for nine applications across the D70, TD70, TMD70, AQD70, TAMD70 and MD70 range. The reman catalogue lists this number against the AQD70D, TAMD70D and TAMD70E, while the AQD70B, TAMD70B, MD70B and TMD70B take 3803031 instead. It is supplied ready for installation with valves and springs fitted, and camshaft-bearing housings included where applicable. It supersedes 3803036, which the older listing carried under an abbreviated Swedish description of the same head. Supplied on an exchange basis: core deposit 3806033 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

• White smoke or steam from the exhaust once warm
• Bubbling in the expansion tank
• Cracks around the valve seats found on strip-down
• Head face out of flatness

🛠️ Service Notes

• Read the suffix letter off the engine plate - the D and E builds take this head and the B builds take 3803031
• At 34.5 kg this is a two-person or hoist lift onto the block
• Find out why the old head failed - a blocked heat exchanger, failed thermostat or tired coolant pump will take the new head the same way
