What material is this coolant hose made from?

This Gates coolant hose is made from EPDM rubber. This material is chosen for its durability and resistance to heat and ozone, which are common factors that can degrade rubber hoses over time.

Why is a molded hose better than a universal one for this application?

A molded hose is shaped to follow the exact bends and curves of the original factory hose. This ensures a clean installation, prevents kinks that could restrict coolant flow, and reduces stress on the hose material compared to a universal hose that might need to be forced into place.

Does this hose come with any clamps?

This part number is for the molded coolant hose only. You will need to reuse your original hose clamps or purchase new ones separately to complete the installation.

Product Details

This Gates 21774 bypass molded coolant hose is constructed from EPDM rubber, which is a strong material known for its resistance to heat and ozone degradation. It's designed to replace the original hose on a variety of GM trucks and vans from the late 80s and early 90s, specifically those with the 2.5L 4-cylinder engine. A molded hose like this follows the specific curves and bends needed to connect the bypass circuit, ensuring a clean installation without kinks or stress on the rubber.

When you're replacing a coolant hose, especially on older vehicles, it's important to use a part that's made to fit the original routing. This Gates hose is shaped to match the factory configuration, which helps maintain proper coolant flow and prevents potential leaks that can come from using a universal hose that doesn't quite bend right. It's a well-built replacement part that addresses a common maintenance item for these trucks and vans.

This hose is a direct fit for many Chevrolet and GMC models, including the S10 pickup, S10 Blazer, Sonoma, Astro, and Safari vans. Make sure to check the fitment details to confirm it's the right part for your specific vehicle.
