Gates 99-13 Chevrolet Silverado V-8 5.3L Lower Molded Coolant Hose

This is the Gates molded lower radiator hose, part number 22437. It's specifically made to fit a wide range of Chevrolet and GMC trucks and SUVs, including popular models like the 1999-2013 Chevrolet Silverado 1500 and the 2000-2014 Chevrolet Tahoe, when equipped with the 5.3L V8 engine. This hose is designed to replace your original equipment hose, ensuring a proper fit and function for your cooling system.

Gates uses EPDM rubber for these hoses, which is known for its resistance to heat, ozone, and coolant chemicals. The molded shape means it follows the exact routing needed for your specific engine application, avoiding kinks or stress points that can happen with universal hose setups. This helps maintain consistent coolant flow, which is crucial for keeping your engine at the right temperature, especially during demanding driving conditions or in hot weather.

Replacing a coolant hose is a common maintenance item, and having the correct molded shape makes the job straightforward. Make sure to check your vehicle's service manual for the proper installation procedure and any other cooling system components you might want to inspect or replace at the same time, like the thermostat or water pump.
