Diesel Engine Water Pump Assy 8976027730 8-97602773-0 for ISUZU FVR 6HE1 6HH1 Truck — OEM Quality
The Diesel Engine Water Pump Assembly with OEM numbers 8976027730 / 8-97602773-0 is a verified direct-fit replacement for ISUZU FVR series heavy-duty trucks equipped with the 6HE1 diesel engine. This water pump is a critical component of the engine coolant circulation system, widely used in ISUZU FVR / FRR / FSR / FTR series trucks and vehicles powered by 6HE1, 6HH1, and 6HK1 engines.
The water pump is driven by the engine crankshaft via a belt. The impeller rotates at high speed inside the pump housing, creating centrifugal force that draws coolant from the radiator, pressurizes it, and pushes it through the engine block and cylinder head water jackets to absorb heat before returning to the radiator for cooling. This water pump assembly features an aluminum housing with a steel impeller and dual sealed ball bearings for long-term reliable operation.
Replace immediately if any occur:
- Engine Overheating — Temperature gauge reads high; engine overheat warning light illuminates (damaged impeller or seized bearings causing insufficient coolant flow)
- Water Pump Noise — Squealing or grinding noises from the pump area during operation (worn bearings or loose impeller)
- Coolant Leakage — Visible coolant seepage from the pump weep hole (failed mechanical seal)
- Poor Cabin Heating — Heater performance degraded (insufficient pump flow to heater core)
- Abnormal Cooling System Pressure — Large temperature difference between upper and lower hoses; radiator fan cycles frequently (reduced pump efficiency)
- Engine Power Loss — High temperature triggering ECU power limitation (limp mode)

IMPORTANT: The water pump is a critical component of the engine cooling system. Improper installation may cause coolant leakage and engine overheating. Installation should be performed by qualified professionals. Ensure the engine is completely cooled before installation.
Installation Guidelines (Refer to workshop manual):
- Safety Prep — Ensure engine is completely cooled; disconnect battery negative terminal
- Drain Coolant — Open radiator drain valve; drain coolant to below pump connection level
- Remove Old Pump — Loosen pump belt; remove pump mounting bolts; remove old pump (catch draining coolant)
- Clean Mounting Surface — Thoroughly clean engine block water pump mounting surface (must be clean for new gasket to seal)
- Inspect Mounting Surface — Check for corrosion, scoring, or warping
- Install New Gasket — Place new gasket on pump mounting surface; ensure alignment dowels are aligned
- Install New Pump — Mount new pump to engine block; torque mounting bolts to workshop manual specification
- Install Belt — Install pump belt; adjust tension to specification
- Refill Coolant — Fill with ISUZU-specified coolant to proper level
- Bleed Air — Start engine; open bleed screw; bleed air from cooling system
- Check for Leaks — Idle engine; check pump connections for leaks
- Check Level — After engine reaches operating temperature, recheck coolant level and top up as needed
Maintenance Schedule:
