Gates 02-09 Chevrolet Trailblazer 6-Cyl. 4.2L Upper Molded Coolant Hose

This is the upper molded coolant hose from Gates, part number 22652, specifically designed for the 4.2L 6-cylinder engine found in many GM SUVs. If you're working on a 2002-2009 Chevrolet Trailblazer, GMC Envoy, or similar vehicle and need to replace a cracked or leaking upper radiator hose, this part will get the job done.

Gates makes these hoses with materials that can handle the heat and pressure under the hood. It's molded to the specific shape needed for your engine, so it fits right without a struggle, unlike some universal hoses that can be tricky to route. This hose connects your engine's thermostat housing to the top of the radiator, circulating coolant to keep your engine from overheating.

When you're replacing a coolant hose, it's always a good idea to check the condition of the lower hose and the radiator itself. Make sure you have new hose clamps ready, as the old ones can sometimes be difficult to reuse.
