Q2: Do you test all products before shipping?
A2: Yes, we conduct 100% testing before shipping.
Q3: Which engine models is this Water Pump compatible with?
A3: This product is designed for specific diesel engine models. If you can provide the engine model or original part number, we can confirm compatibility before shipping to avoid incompatibility issues.
Q4: After installing a new engine water pump, the water temperature is still high. Is this a water pump quality issue?
A4: This situation usually requires further investigation of other components in the cooling system for potential faults. For example: is the thermostat stuck in the closed position, preventing the main circulation from opening? Is the radiator externally blocked or internally scaled? Is the coolant of poor quality causing corrosion or scaling in the water passages, affecting heat dissipation efficiency?
Q5: Why should the fan mains tension be checked when replacing the water pump?
A5: Improper fan belt tension can cause overload or slippage of the new water pump bearings, leading to poor coolant circulation. Therefore, preheating is necessary.
