Gates 85-86 Chevrolet C & K Series Pickup V-6 4.3L Upper Molded Coolant Hose

This molded coolant hose from Gates is built with EPDM rubber, a material known for its resistance to heat and coolant chemicals. It's specifically shaped to fit the upper radiator hose connection on 1985-1987 Chevrolet and GMC C/K/R/V series trucks equipped with the 4.3L V6 engine. A proper fit is crucial for preventing leaks and ensuring your engine stays cool.

Gates designs these hoses to match the original equipment's form and function, meaning it should install without a fuss. The molded shape ensures it won't kink or collapse under vacuum, which can happen with universal hose sections. This helps maintain consistent coolant flow, keeping your engine at its optimal operating temperature, especially during demanding tasks or hot weather.

When you're replacing your coolant hoses, it's often a good idea to check the condition of the lower hose and thermostat as well. Having the right hose makes the job straightforward, helping you get your truck back on the road reliably.
