PARTS DESCRIPTION
Product Overview
Coolant must circulate consistently to carry heat away from critical engine areas during operation. The 4TNV88 Water Pump is supplied for compatible Yanmar engine repair and replacement requirements, with fitment confirmation based on the engine information and pump reference.
For repair workshops and parts buyers, accurate matching is especially important because visually similar pumps may use different mounting patterns or connection layouts. Confirming the removed unit before ordering is recommended.

Why This Part Matters
Cooling performance depends on the water pump working together with the thermostat, radiator, hoses, and internal coolant passages. The pump must match the engine’s mounting and flow arrangement so the system can operate as designed. Accurate replacement selection is particularly important when one engine family has several pump versions.
Before installation, inspect related gaskets and sealing surfaces. Reusing damaged sealing parts may cause leakage even when the replacement pump itself is correctly matched.
