129927-42002 Isuzu Water Pump for 4TNV98 Engine – Fit for Sany Sumitomo Excavator
This product is a water pump, with part number 129927-42002, specifically designed for the Isuzu 4TNV98 series diesel engine. The water pump is a core component of the engine cooling system, responsible for driving coolant circulation between the engine water jacket and the radiator, dissipating the heat generated during engine operation to ensure the engine always runs within the optimal temperature range. Manufactured with high-quality cast iron or aluminum alloy housing and precision-machined impeller, this pump offers excellent sealing performance and durability. It is widely used in Sany and Sumitomo excavators.
OEM Specification – Manufactured to strict Isuzu OE standards with precise dimensions for direct replacement without any modification.
High-Quality Material – Pump housing made of high-strength cast iron or aluminum alloy; impeller precision-cast for corrosion and cavitation resistance.
Efficient Pumping – Impeller designed with fluid-optimized geometry for high pumping efficiency and sufficient coolant flow to meet all engine cooling demands.
Reliable Sealing – Equipped with OEM-spec mechanical seal or water seal to prevent coolant leakage.
Precision Bearing – Fitted with high-quality maintenance-free bearings for smooth operation, long service life, and reduced maintenance costs.

Inspect the new water pump for smooth rotation, abnormal noise, or binding before installation.
Always replace the mating gasket and tighten bolts to OEM-specified torque during installation.
After installation, refill with proper coolant and bleed the cooling system to remove trapped air, preventing poor heat dissipation due to air locks.
It is recommended to inspect the belt, tensioner, and thermostat when replacing the water pump; replace them if necessary.
Replace the water pump immediately if water leakage, abnormal noise, or bearing play is found, to prevent engine overheating.
