This is a high-quality gasket designed to seal the coolant pipe connection on Volvo and Renault trucks, specifically for the FM9, Premium II, Kerax, and Magnum models. It prevents coolant leaks from the engine's cooling system, ensuring proper heat exchange and preventing overheating. A failed gasket can result in visible coolant leaks, a drop in coolant level, and potential engine overheating.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failed coolant pipe gasket is often a visible leak of coolant around the pipe connection point. If ignored, the leak will worsen, leading to a significant loss of coolant, potential engine overheating, and the formation of steam or a sweet odor. Continued operation with a coolant leak can cause severe damage to the engine due to overheating.
Ensure the mating surfaces on both the pipe and the engine block are perfectly clean and free of any debris or old gasket material before installation. Do not overtighten the bolts, as this can distort the pipe or damage the gasket, leading to immediate leaks.
Inspect the coolant pipe itself for any signs of corrosion or damage, and check the condition of the adjacent hoses and clamps in the cooling system.
