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 radiator is often a rising engine temperature gauge. If ignored, the engine may begin to overheat, leading to reduced power and potential coolant loss. Continued operation with an ineffective radiator risks severe engine damage due to excessive heat.

Installation Tip

Before installing, flush the cooling system thoroughly to remove any debris that could clog the new radiator. Avoid overtightening hose clamps, as this can damage the radiator's plastic tanks.

Service Note

Inspect all radiator hoses, clamps, and the water pump for signs of wear or leakage during radiator replacement.
