What material is this coolant hose made from?

This Gates coolant hose is constructed from a heat-resistant rubber compound. This material is chosen to withstand the high temperatures and pressure found within the engine's cooling system.

Does this hose come with new hose clamps?

This product includes the molded coolant hose only. New hose clamps are not included and should be purchased separately if your existing ones are worn or damaged.

Why is the shape of the hose important?

The molded shape is critical because it's designed to follow the exact routing of the original factory hose. This ensures a proper fit, prevents kinks, and avoids stress on the hose material, which contributes to its longevity.

Product Details

This Gates 21055 lower molded coolant hose is specifically shaped for the 1985-1988 Chevrolet Astro with the 4-cylinder 2.5L engine. It's designed to replace the original hose, ensuring a proper fit and maintaining the integrity of your cooling system. A well-built hose is crucial because it carries coolant from the radiator to the engine, and a leak or collapse here can quickly lead to overheating.

Gates uses a strong, heat-resistant rubber compound for this hose, similar to what the factory uses. This helps it stand up to the constant temperature fluctuations and pressure found under the hood. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force the hose into place. This attention to detail helps prevent kinks or stress points that could lead to premature failure.

When you're replacing a coolant hose, it's always a good idea to inspect the surrounding components. Make sure your hose clamps are in good shape and consider replacing them if they show signs of rust or weakness. This ensures a secure connection and prevents coolant leaks.
