What is the difference between a molded and a universal coolant hose?

A molded coolant hose is shaped to fit a specific vehicle's engine bay and routing, like this Gates hose. Universal hoses are flexible and can be cut to length, but may not fit as cleanly or securely as a molded hose.

Does this hose come with clamps?

This product listing is for the molded coolant hose only. Clamps are typically sold separately and are not included with this part.

What other parts might I need when replacing a coolant hose?

When replacing a coolant hose, it's a good time to inspect your radiator, thermostat, and water pump. You may also need new hose clamps and fresh coolant for a complete service.

Product Details

When you're working on your 1985 or 1986 Chevrolet or GMC pickup with the 4.3L V-6 engine, you'll need the right parts to get the cooling system back in shape. This Gates molded lower coolant hose is specifically shaped to fit your truck, connecting the radiator to the engine block to allow coolant to circulate. A proper fit is key to preventing leaks and ensuring your engine stays at the right temperature.

Gates makes this hose from materials that can handle the heat and pressure found in your cooling system. It's built to resist cracking and collapsing, which can happen with older or lower-quality hoses. This molded design means it follows the factory routing precisely, making installation straightforward without needing to bend or force the hose into place. It's a well-built replacement part designed to keep your engine running cool.

This hose is designed for a range of Chevrolet and GMC C/K, R, and V series trucks from the mid-80s. Make sure to check the fitment details to confirm it's the correct lower hose for your specific vehicle.
