Cast Iron Heat-Resistant Water Pump Direct Replacement for Hino J08E Engine Cooling Pump

The Water Pump Assembly (OEM Number: 16100-E0021) is a premium-quality, direct replacement cooling system component designed for Hino 500 series trucks equipped with the J08E diesel engine. This engine water pump circulates coolant through the engine block, cylinder head, and radiator to maintain optimal operating temperature, preventing overheating and ensuring efficient performance.

• OE Quality: Manufactured to Hino dimensional and material specifications for perfect fit and reliable cooling
• Durable Construction: Withstands extreme pressures and temperatures in heavy-duty vehicle cooling systems
• Optimized Coolant Circulation: Engineered impeller and precision coolant ports ensure efficient coolant flow
• Heavy-Duty Bearing: Sealed ball bearing with high-temperature grease for long life under heavy loads
• Mechanical Seal: Ceramic or carbon face seal prevents coolant leakage and resists wear
• Versatile Mounting: 8 bolt-hole configuration for secure installation across various engine configurations
• Direct Replacement: Matches OE mounting holes, inlet/outlet positions, and pulley fitment
• 12-Month Warranty: Guaranteed quality and reliability

This water pump is specifically designed for Hino 500 series trucks with J08E engine.

1. Drain coolant from radiator and engine block
2. Remove drive belt by loosening tensioner or idler pulley
3. Remove fan and fan clutch (if applicable) by unbolting from water pump flange
4. Disconnect hoses, noting positions (inlet, outlet, bypass)
5. Unbolt old water pump, noting bolt lengths and positions
6. Clean mating surface on engine block, removing old gasket material without scratching surface
7. Compare new pump with old to check mounting, port locations, and pulley fit
8. Install new gasket on block (some gaskets have adhesive backing)
9. Install new water pump and tighten bolts in sequence to specification (typically 20-30 Nm)
10. Reconnect hoses using new hose clamps if needed
11. Reinstall fan and fan clutch, torquing bolts to specification
12. Reinstall drive belt with correct routing and tension
13. Refill coolant using recommended type, filling slowly to avoid air pockets
14. Bleed the cooling system by running engine with heater on high, adding coolant as needed
15. Check for leaks at pump gasket and hose connections
16. Test drive while monitoring engine temperature gauge
