What is the main purpose of the upper coolant hose?

The upper coolant hose carries hot coolant from the engine to the radiator. It's a critical part of your vehicle's cooling system, helping to regulate engine temperature and prevent overheating.

What makes this a 'molded' hose?

A molded hose is shaped during manufacturing to match the specific bends and curves of the original equipment hose. This ensures a precise fit without needing to bend or force the hose into place during installation.

Does this hose come with clamps?

This Gates coolant hose is sold individually and does not include hose clamps. You will need to reuse your existing clamps or purchase new ones separately to complete the installation.

Product Details

If you're working on your 2012 or 2013 Chevrolet Silverado 1500 with the V-6 4.3L engine, this Gates upper molded coolant hose is what you need to replace a worn or leaking hose. It's designed to fit right in place of the original equipment hose, helping to keep your cooling system working properly.

Gates makes these hoses with materials that stand up to the heat and pressure found in your engine's cooling system.

A properly functioning upper hose is key to preventing your engine from overheating, especially during demanding driving conditions.
