✅ Compatible with multiple Linhai ATV models (300cc / 400cc series)

📖 Product Overview

This is a genuine Linhai quality impeller shaft assembly (water pump impeller assembly), a critical component of the engine cooling system. Direct replacement for OEM part number: 22801a / 170M.15.4a.

The impeller assembly drives coolant circulation between the engine water jacket and radiator, dissipating heat generated during engine operation to maintain normal operating temperature. Damaged, corroded impeller blades or shaft wear can lead to poor coolant circulation and engine overheating. This assembly is manufactured with corrosion-resistant materials and precision casting to ensure long-term reliable cooling performance.

✨ Genuine Quality: Manufactured to Linhai original specifications. Precision cast impeller blades, corrosion-resistant and high-temperature resistant, ensuring proper cooling system operation.

⚠️ Failure Symptoms — When to Replace the Impeller Assembly:

Engine overheats easily, temperature gauge reads high
Poor coolant circulation, large temperature difference between radiator inlet and outlet hoses
Unusual noise from water pump area (loose impeller or worn bearings)
Coolant leakage (failed water pump seal)
Inspection reveals corroded, cracked, or missing impeller blades

If any of the above symptoms occur, replace the impeller assembly promptly to prevent more serious engine damage from overheating.

✅ Installation Tip: When replacing the impeller assembly, always replace the water pump seal and gasket simultaneously to prevent coolant leakage after reassembly.
