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 coolant tank is often visible coolant leaks, especially around the tank body or hose connections. If ignored, the tank may crack further, leading to a significant loss of coolant and potential engine overheating. Continued operation without adequate coolant can cause severe engine damage.

Installation Tip

Ensure all hose connections are clean and free of debris before attaching them to the new tank to prevent leaks. Do not overtighten the mounting bolts, as this can crack the plastic tank.

Service Note

Inspect all cooling system hoses and the radiator for leaks or deterioration when replacing the coolant tank.
