Gates 22917 Radiator Coolant Hose - Lower

Gates 22917 Molded Coolant Hose Overview

Gates 22917 is a molded radiator coolant hose built for lower cooling-system routing on select Chevrolet, GMC, Hummer, and Isuzu applications. It uses EPDM construction and OEM-style molded dimensions to match the original hose path and connection sizes.

The Gates Molded Coolant Hose line covers upper, lower, bypass, heater, and other coolant applications with OE-style specifications. That makes this Gates 22917 hose a direct replacement choice when you need a formed lower radiator hose for the correct fit and routing.

Key Features

• Molded design for the original hose shape and routing
• 1.5 in. inside diameter at both ends
• 23.4 in. centerline length
• Lower radiator coolant hose application
• No spring and no quick-connect fittings

Detailed Description

This molded coolant hose is engineered for lower radiator hose service on 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon, 2006-2010 Hummer H3, 2009-2010 Hummer H3T, 2007-2008 Isuzu i-370, and 2006 Isuzu i-350. The formed profile helps maintain the factory hose path, while the EPDM material is suited for coolant exposure and underhood temperature cycling. If you are replacing a worn lower hose on a Chevrolet Colorado or GMC Canyon, Gates 22917 provides the correct molded layout for the listed applications.

What It Helps Fix

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse in the original hose
• Improper hose routing after a failed replacement
• Cooling-system service on vehicles with the listed lower hose application
• Fitment issues caused by using a straight hose in a molded application

Installation Notes and Tips

Verify the hose shape, end diameters, and centerline length against the original part before installation. Inspect hose clamps, necks, and adjacent cooling-system components for wear or corrosion, and replace any damaged sealing surfaces before refilling the system. Confirm the vehicle application by year, make, model, and lower-position routing for the Chevrolet Colorado, GMC Canyon, Hummer H3, Hummer H3T, Isuzu i-370, or Isuzu i-350.
