Installation Notes
- Ensure the engine is cool and disconnect the battery. Drain the engine coolant and oil.
- Disconnect all electrical connectors, fuel lines, exhaust, and intake components attached to the cylinder head.
- Loosen and remove the cylinder head bolts in the sequence specified by the manufacturer (typically from the outside inwards).
- Carefully lift the cylinder head off the engine block. Avoid using pry tools that could damage the mating surfaces.
- Remove the old head gasket and thoroughly clean any remaining gasket material, carbon deposits, or sealant from both the cylinder head and engine block surfaces.
- Position the new gasket correctly on the engine block, ensuring all holes align with dowel pins and passages.
- Carefully lower the cylinder head back onto the new gasket and block.
- Install new head bolts (recommended) and tighten them in stages using the correct torque sequence and specifications from your service manual.
- Reassemble all other components in the reverse order of removal.
- Refill engine oil and coolant, reconnect the battery, and check for leaks upon starting the engine.
Troubleshooting & FAQ
How do I know if my Volvo Penta D3 needs a new head gasket?
Common symptoms of a blown head gasket include engine overheating, white smoke from the exhaust (coolant burning), milky or foamy engine oil (coolant mixing with oil), loss of compression, and unexplained coolant loss. If you notice any of these signs, have your engine inspected immediately.
What does a "3 hole, Class C" gasket mean?
Volvo Penta sometimes uses gaskets of different thicknesses to compensate for variations in engine block or head machining. The number of holes (or notches) is a classification system to identify the gasket's thickness. "Class C" with 3 holes corresponds to a specific thickness. It's critical to use the same class as the one you are replacing unless instructed otherwise by a technician after machine work.
Is this gasket compatible with all D3 engine versions (e.g., D3-190I-C)?
Yes, this gasket is listed as compatible with the entire D3 series from 110 to 190 HP, including all sub-model designations (A, B, C, I). However, you must always verify the part number 30731263 is correct for your specific engine serial number before ordering.
What is the recommended replacement interval?
A cylinder head gasket is not a routine maintenance item and is only replaced when it fails. Its lifespan depends on operating conditions, maintenance, and engine health. With proper care, a quality head gasket should last for many thousands of hours.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
