Which reference numbers are associated with this part?

The listed Volvo Penta reference numbers are 3582436, 3583787, 876104, and 876530.

Is this a complete engine gasket set?

No. This listing is for one head gasket seal. It is not represented as a complete engine overhaul gasket set or as a full cylinder-head service kit.

Do I need sealant during installation?

Follow the service manual for your exact engine variant. Do not apply sealant unless the manufacturer specifically requires it for the gasket location and installation procedure.

What are common signs of a failed head gasket?

Possible symptoms include unexplained coolant loss, overheating, white exhaust smoke, coolant contamination, combustion pressure in the cooling system, or reduced compression. Proper diagnosis should be completed before disassembly.

Should the cylinder head be inspected before fitting a new gasket?

Yes. Check the cylinder head and block for warping, cracks, corrosion, and damage to the mating surfaces. Correct any underlying issue before installing the replacement seal.

Is this an OEM part?

This is an aftermarket replacement. Volvo Penta reference numbers are provided for identification and fitment comparison; the replacement is not sold as a Volvo Penta-branded OEM component.

Safety & Important Information

• Verify the complete engine model designation and reference number before ordering.
• Compare the replacement gasket with the original part and confirm its orientation before installation.
• Use the applicable manufacturer service manual for torque values, tightening sequence, coolant procedures, and sealant requirements.
• Professional installation is recommended because cylinder-head service requires correct disassembly, inspection, and torque procedures.
