Engine Water Pump

The engine cooling water pump is powered by the engine and circulates the
liquid coolant through the water pump cooling system.

Solutions to Water Pump Failure

Leaks and noise are signs of pump failure, which can be caused by ageing and
wear or overheating conditions, and are often caused by other faults in the
system. It is driven by belts (either dedicated serpentine belts or rarely by
timing belts), so proper belt maintenance is critical to its operation.

Leakage

Causes: Improper installation of car engine water pump or improper use of
sealing gasket.

Solutions: If it is a new water pump, check carefully remove and reinstall the
pumps. Strictly abide by the torque specification and ensure seal gasket is in
the right condition.

Rust and Corrosion

Causes: Polluted coolant incompatible coolant or a mixture of coolants of
different chemical composition

Solutions: Before installing a new pump, flush the cooling system thoroughly.
When using sealants, clean the edges and surfaces of parts and apply the new
seal evenly along the edges of parts.

Cavitation

Causes: Bubbles form at the coolant inlet of the pump. As the pressure in the
system increases, the bubbles can implode and cause damage.

Solution: Replace the pump, Flush the cooling system thoroughly before
installing the new pump and refill the system with the correct coolant
recommended by the vehicle manufacturer.

Internal-accumulated sediment

Causes: Contaminated coolant incompatible coolant or a mixture of coolants of
different chemical composition

Solution: Replace the pump, Flush the cooling system thoroughly before
installing the new pump and refill the system with the correct coolant
recommended by the vehicle manufacturer.

Application of Water Pump
Thermal management of powertrains of Conventional Inter Combustion Engine

The engine drives the mechanical water pump to provide circulation power, and
the thermostat controls the circulation switch.

Thermal management of new energy vehicles

Electric Water Pump is our target product lines in the future.
