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 coolant tank is often visible coolant leaks, especially around the seams or fittings. If left unaddressed, the engine may overheat due to insufficient coolant volume and pressure loss. Continued operation risks severe engine damage from prolonged high temperatures.

Installation Tip

Ensure all mating surfaces are clean and free of debris before installing the new coolant tank to guarantee a proper seal. Do not overtighten hose clamps, as this can damage the tank's connection points.

Service Note

When replacing the coolant tank, inspect all cooling system hoses for signs of wear or swelling and check the condition of the radiator cap.
