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

The first sign of a failing oil cooler gasket kit is often the appearance of coolant within the engine oil, visible as a milky or frothy substance on the dipstick or oil fill cap. Conversely, oil may appear in the coolant reservoir. If left unaddressed, this contamination can lead to severe lubrication failure and internal engine damage.

Installation Tip

Ensure the mating surfaces of the oil cooler and engine block are perfectly clean and free of any old gasket material or debris. Do not reuse old bolts; use new ones if specified, and torque them evenly in a crisscross pattern.

Service Note

When replacing the oil cooler gasket kit, inspect the oil cooler core for any signs of blockage or damage.
