ISUZU Water Pump 4HK1 - 8980228221
High-quality coolant pump (water pump) designed for ISUZU 4HK1 engines. This component is the main element of the cooling system, forcing the circulation of coolant between the engine and the radiator. It ensures the maintenance of the optimal operating temperature of the power unit, protecting it from overheating and costly breakdowns. It features high efficiency of the impeller system and excellent bearing resistance to harsh operating conditions in construction machinery and heavy-duty vehicles.

Workshop Tip: A water pump failure most often manifests itself as a coolant leak from the weep hole, unnatural noise coming from the bearing, or a tendency for the engine to overheat. When replacing the pump, it is absolutely necessary to thoroughly clean the mating surface on the engine block and use a new gasket (or a dedicated sealant if the specification requires it). This is also an ideal time to verify the condition of the serpentine/V-belt and its tensioner. Fill the system with new coolant and bleed it thoroughly.
