High Light Heavy-duty heat-resistant rubber Water Hose4HK1 5.2L Diesel Engine Water HoseOEM Quality Engine Coolant Inlet Hose
Water Hose 8973792281 8-97379228-1 for ISUZU 700P 4HK1 — OEM Quality
Product Overview

The Water Hose (Engine Coolant Inlet Hose) with OEM numbers 8973792281 / 8-97379228-1 is a verified direct-fit replacement for ISUZU 700P / NPR / NQR / NRR series trucks equipped with the 4HK1 5.2L diesel engine. This water hose is a critical component of the engine coolant circulation system, responsible for delivering coolant from the cylinder block to the cylinder head (or from the thermostat to the cylinder block), ensuring the engine operates within optimal temperature range.

How It Works

The water hose is installed between the engine cylinder block and cylinder head (or between the thermostat and cylinder block), serving as a vital passage in the engine coolant circulation path. Driven by the water pump, coolant flows through this hose from the block to the head (or from the thermostat to the block), absorbing heat generated by combustion before flowing to the radiator for cooling, completing the full cooling cycle. The hose is constructed from high-temperature, oil-resistant, pressure-resistant rubber material, ensuring long-term stable operation under high-temperature, high-pressure engine conditions.

Failure Symptoms

Replace immediately if any of these symptoms occur:

  • Coolant Leakage — Green/pink coolant seepage visible at hose connections or body; coolant stains on the ground
  • Engine Overheating — Temperature gauge reading high; engine overheat warning light illuminates
  • Rubber Aging/Cracking — Visual inspection reveals cracks, bulges, or hardening on hose surface
  • Abnormal Coolant Consumption — Coolant level drops faster than normal; frequent top-ups required
  • Steam from Engine Bay — White steam rising from engine bay while driving
  • Poor Cabin Heating — Heater performance degraded
Verified Performance Data
  • Installation Success Rate: 98.5% direct fitment rate — confirmed across 78 repair orders
  • Weight: 0.08kg — lightweight design for easy installation
  • Material: Heavy-duty heat-resistant rubber
  • Operating Temperature Range: -40°C to +120°C
  • Operating Pressure: Withstands normal cooling system pressure (approx. 1.0–1.5bar)
  • HS Code: 400931000 — standard customs classification
  • 100% Factory Tested — Every hose undergoes comprehensive inspection
  • Direct OEM Interchange — Direct replacement for ISUZU original parts

Important Installation Notes
  • The water hose is a critical component of the engine cooling system — aging and cracking cause coolant leakage and engine overheating, potentially leading to engine seizure or cylinder head warpage
  • Recommended to inspect other cooling system hoses when replacing — replace all aging hoses simultaneously
  • Ensure hose connections are clean and free of debris during installation; use OEM-spec hose clamps
  • Refill coolant and bleed air from the system after installation to ensure proper cooling system operation
  • For 100% accurate fitment, please provide VIN (Chassis Number) or engine model

Installation & Maintenance

IMPORTANT: The water hose 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
  1. Safety Prep — Ensure engine is completely cooled; disconnect battery negative terminal
  2. Drain Coolant — Open radiator drain valve; drain coolant to below hose connection level
  3. Remove Old Hose — Loosen hose clamps at both ends; carefully remove old hose
  4. Clean Connections — Thoroughly clean cylinder block and cylinder head hose connections
  5. Inspect Connections — Check connections for corrosion, scoring, or deformation
  6. Install New Hose — Install new hose onto connections; ensure fully seated
  7. Install Clamps — Install OEM-spec clamps; torque to workshop manual specification
  8. Refill Coolant — Fill with ISUZU-specified coolant to proper level
  9. Bleed Air — Start engine; open bleed screw; bleed air from cooling system
  10. Check for Leaks — Idle engine; check hose connections for leaks
  11. Check Level — After engine reaches operating temperature, recheck coolant level
