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

This is the Gates 22651 lower molded coolant hose, specifically made for the 6-cylinder, 4.2L engine found in a range of vehicles like the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x from the early 2000s through 2009. This hose is a direct replacement for your original, carrying coolant from the radiator to the engine block, which is crucial for keeping your engine from overheating.

Gates uses a strong, heat-resistant rubber compound for these hoses, built to withstand the constant expansion and contraction from engine heat and pressure. The molded shape means it follows the exact path of your factory hose, making installation straightforward without needing to bend or force it into place. This helps prevent kinks or stress points that could lead to premature failure, ensuring a reliable connection for your cooling system.
