Installation & Application Notes

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.

Failure Symptoms

Initial signs of failure may include a gradual increase in engine oil temperature readings. If left unaddressed, the oil cooler's reduced efficiency can lead to sustained high oil temperatures, increasing wear on engine components. Prolonged operation with a failing oil cooler risks severe engine damage due to inadequate lubrication and cooling.

Installation Tip

Ensure the mounting surfaces on the engine block and the cooler are perfectly clean and free of any old gasket material before installation. Overtightening the mounting bolts can distort the cooler housing, leading to leaks.

Service Note

When replacing the oil cooler, it is advisable to inspect the engine oil filter and the oil itself for any signs of contamination or metal particles.
