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 indication of a failing radiator might be a persistent high-temperature warning light or visible coolant leaks. If ignored, the engine will likely overheat, leading to reduced power and potential damage to other engine components. Severe radiator failure can result in complete loss of coolant and engine shutdown.

Installation Tip

Thoroughly flush the cooling system before installing the new radiator to remove any residual debris that could clog the new unit. Ensure all hose connections are secure and properly tightened to prevent leaks.

Service Note

Inspect all coolant hoses, the water pump, and the thermostat for leaks or signs of wear when replacing the radiator.
