3805222 Cylinder Head Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a cylinder head, in the Engine group. It is the refundable charge raised against the old cylinder head when the exchange unit is bought, and it comes back once the worn cylinder head is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3802222, which is the number to quote for the component itself. It is listed for a single application in the TAD series. The other cylinder head cores in this run of numbers are 3805211, 3805212, 3805221, 3805223 and 3805224; this is the only one of the six carrying a published application list, so the fitment is what separates it from the rest.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1346GE

• Engine Family: TAD

⚙️ Key Features

• Core deposit line, not a cylinder head you can fit
• Belongs with the exchange unit, part number 3802222
• Refunded when the old cylinder head is returned
• Listed for a single application in the TAD series
• Engine group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the cylinder head itself closes the top of the cylinders and carries the valves, seats and their operating gear, sealing the combustion chamber against pressure.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the cylinder head being exchanged
• Coolant loss with white smoke at the exhaust and a header tank that pressurises
• Overheating under load, with bubbles or combustion smell in the coolant
• Rough running or a misfire on one cylinder that a compression test confirms
• Oil and coolant mixing, or coolant weeping down the outside of the block

🛠️ Service Notes

• The charge is refunded when the worn cylinder head is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3802222
• Have the block face checked and use a new head gasket set and new head bolts where they are single-use, and find out what overheated the old head before the exchange unit goes on

📦 Condition

• Refundable core deposit - not a physical part
