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 initial symptom of a failing cooling hose is often a visible coolant leak, typically appearing as a small drip or puddle under the machine. If ignored, the hose can rupture, leading to a rapid loss of coolant, severe engine overheating, and potential engine damage.

Installation Tip

Ensure the connection points on the engine and radiator are clean and free of old hose material or corrosion before attaching the new hose. Do not force the hose onto the fittings; it should slide on with moderate pressure.

Service Note

Inspect the radiator cap and thermostat for proper operation, and check the coolant level and condition when replacing the cooling hose.
