⚙️ Key Features

• Moulded profile matched to the D12 oil-cooler/side-cover joint
• Oil- and heat-resistant elastomer construction
• Long-form gasket follows the cooler and block passage layout
• Provides controlled compression around oil and coolant galleries
• Mating surfaces must be clean and flat before installation
• Single-use replacement is recommended whenever the side cover is removed

🔌 Function

Seals the D12 oil-cooler/side-cover joint against engine-oil and coolant leakage.

⚠️ Common Signs of Failure

• Oil or coolant leaks along the side cover
• Oil and coolant begin to cross-contaminate
• The gasket is swollen, split or permanently compressed
• Residue or staining appears around the cooler joint
• Replacement is required whenever the side cover is removed

🛠️ 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
