This is a coolant water pump responsible for circulating engine coolant through the D16C engine's cooling system to dissipate heat. It is built to OEM specifications, ensuring efficient flow rates and durability, unlike a worn pump with a failing bearing or impeller.

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 symptom is often a rising engine temperature gauge, indicating inadequate coolant circulation. If ignored, the engine can quickly overheat, leading to potential damage to gaskets, cylinder heads, and other critical components. Continued operation without proper cooling can cause severe engine damage.

Installation Tip

Always replace the thermostat and inspect the condition of the drive belt and tensioner when installing a new water pump. Ensure the mounting surface is clean and free of corrosion before applying sealant or gasket.

Service Note

Replace the thermostat and flush the cooling system when replacing the water pump to ensure optimal performance and prevent contamination.
