21186298 Gasket | Genuine Volvo Penta Part

🔧 Product Description

Genuine cylinder-head gasket supplied for the specific Volvo Penta engine and piston-protrusion class assigned to part number 21186298. It must be selected by the engine product number, serial number and original gasket identification.

⚙️ Key Features

• Genuine Volvo Penta cylinder-head gasket
• Application-specific bore, oil and coolant passages
• Controlled gasket thickness or identification class
• Designed for diesel combustion pressure and temperature
• Not interchangeable with 21186299 unless Volvo Penta data specifies it

🔌 Function

The gasket seals combustion pressure, coolant and lubricating-oil passages between the cylinder block and cylinder head.

⚠️ Common Signs of Failure

• Coolant pressurising or bubbling
• Combustion gas in the cooling system
• External coolant or oil leakage
• White exhaust smoke

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
