📋 Product Overview

This product is a Linhai OEM-spec impeller shaft gear (water pump drive gear), part number 22815 / 170M.15-4. This gear is installed in the engine water pump drive mechanism and is manufactured from high-quality engineering plastic, offering advantages such as light weight, self-lubrication, and low operating noise. It transmits power to the water pump impeller, driving coolant circulation to ensure proper engine cooling system operation.

Over time, the water pump drive gear may experience tooth wear, cracking, or breakage, leading to insufficient pump speed or complete failure, causing poor coolant circulation and engine overheating. Timely replacement of a damaged water pump drive gear is essential to maintain proper engine cooling system operation.

✅ Genuine Quality Assurance: Manufactured strictly to Linhai original technical standards. Tooth profile and dimensional accuracy are identical to the original part for a perfect replacement.
