Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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 symptoms of a failing oil cooler may include a gradual rise in engine oil temperature, especially under heavy load. If left unaddressed, the cooler's reduced efficiency can lead to oil breakdown and inadequate lubrication, increasing engine wear. Continued operation with a compromised oil cooling system risks significant internal engine damage.

Installation Tip

Ensure all mating surfaces are perfectly clean and dry before installation to guarantee a leak-free seal. Avoid overtightening the mounting bolts, as this can warp the cooler or damage the gasket.

Service Note

Inspect the engine oil filter and oil lines for any signs of blockage or contamination when replacing the oil cooler.
