What is the primary function of this lower coolant hose?

The lower coolant hose connects your radiator to the engine's water pump. It allows coolant to flow from the radiator, after being cooled, back into the engine to maintain optimal operating temperature.

Why is a molded hose important for my vehicle?

A molded hose is shaped precisely to fit the original routing of your vehicle's factory hose. This ensures a clean installation without kinks or stress points, which can happen if you try to force a universal hose into place.

What material is this hose made from?

This Gates coolant hose is constructed from a heat-resistant rubber compound. This material is chosen for its ability to withstand the high temperatures and pressure fluctuations found in a vehicle's cooling system.

Product Details

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.
