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 around the tank or its connections. If ignored, the coolant level will drop, leading to inadequate engine cooling and potential overheating. Continued operation with a compromised coolant tank can cause severe engine damage due to excessive heat.

Installation Tip

Ensure the cooling system is completely cool before attempting to remove the old tank to avoid burns. Securely tighten the new tank's mounting bolts and hose clamps to prevent leaks.

Service Note

Inspect the radiator cap and all coolant hoses for signs of wear or leaks when replacing the coolant tank.
