Gates 87-93 Chevrolet S Series Pickup 4-Cyl. 2.5L By Pass Molded Coolant Hose

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.
