Installation and Maintenance Tips:

1.Always replace the gasket O-ring with a new one — reusing the old gasket is the most common cause of post-installation leaks.

2. Replace the thermostat and coolant at the same time; overheating history damages new seals quickly.

3. Inspect the drive belt and radiator hoses; aging belts slip and reduce pump speed.

4. Torque mounting bolts in a cross pattern to the service-manual spec — over-tightening cracks the aluminum housing.

5. After installation, run the engine at idle, check the weep hole for drips, then re-check coolant level after the first full work day.

Quality Control Process:

1.Material inspection — housing casting density and hardness checked per batch.

2. Dimensional check — mounting flange, shaft height and bore tolerance measured against OEM drawings.

3. Impeller balancing — dynamic balance test to eliminate vibration.

4. Bench test — flow rate, head pressure and 30-minute leakage test at rated RPM.

5. Final inspection and packing — visual check, anti-rust oil, sealed plastic bag, carton and wooden case.
