Product Overview

The 8-97209949-1 Bypass Water Hose (also known as coolant bypass hose or water pump bypass hose) is a high-quality replacement part designed specifically for the Isuzu 4HK1 engine. This hose is used in the engine cooling system bypass circuit, allowing coolant to circulate internally through the engine when the thermostat is closed, accelerating engine warm-up and preventing excessive cooling system pressure, ensuring the engine reaches optimal operating temperature quickly during cold starts and low-temperature conditions.

This hose is also compatible with Hitachi and Sumitomo excavators. Manufactured to original equipment specifications with premium heat-resistant rubber material, it offers excellent flexibility and aging resistance, making it an essential component for engine cooling system maintenance and repair.
