Gates 80-86 Chevrolet C & K Series Pickup V-8 7.4L Lower Molded Coolant Hose

If you're working on a 1973-1988 Chevrolet or GMC truck or van with the big 7.4L V8 engine, this Gates molded lower radiator hose (part number 20842) is what you'll need to get the coolant flowing correctly. It's specifically shaped to fit the routing from the radiator to the water pump on these vehicles, ensuring a clean installation without any kinks or strain.

Gates makes these hoses from a durable EPDM rubber compound that's resistant to heat and coolant chemicals, so it'll hold up to the demands of your engine. The molded shape means it's a direct fit, so you won't have to fight with it to get it into place. This hose is designed to replace the original part, helping to maintain proper engine temperature and prevent overheating.

When you're replacing a coolant hose, it's always a good idea to check the condition of the upper hose and thermostat as well. Make sure you have fresh coolant ready to go, and be sure to properly bleed the system after you're done to avoid air pockets.
