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 a failing oil cooler core include a gradual rise in engine oil temperature readings. If left unaddressed, this can lead to increased wear on engine components due to insufficient lubrication. Continued operation with an overheated oil system risks severe engine damage.

Installation Tip

Ensure the mounting surfaces are clean and free of debris before installation to guarantee a proper seal. Avoid overtightening mounting bolts, which can distort the core and cause leaks.

Service Note

Inspect engine oil and coolant levels, and check for any signs of oil-to-coolant contamination during replacement.
