What is EPDM rubber and why is it used for coolant hoses?

EPDM (ethylene propylene diene monomer) rubber is a synthetic rubber known for its excellent resistance to heat, ozone, and weathering. For coolant hoses, this means it can withstand the high temperatures and chemical exposure from engine coolant without degrading quickly.

Should I replace my upper radiator hose at the same time?

It's generally recommended to replace both the upper and lower radiator hoses when one fails. Hoses degrade over time due to heat and pressure, so if the lower hose is worn, the upper hose is likely not far behind. Replacing them together ensures your cooling system is fully refreshed.

Does this hose come with clamps?

This Gates coolant hose does not include installation clamps. You will need to use your existing clamps or purchase new ones separately to secure the hose to the radiator and engine connections.

Product Details

This Gates molded coolant hose is built with EPDM rubber, a material known for its resistance to heat and coolant chemicals. It's specifically shaped to fit the lower radiator hose position on your 1997-1999 Chevrolet Malibu equipped with the 3.1L V-6 engine. A proper fit is crucial here, as a hose that's too tight or too loose can kink or collapse, restricting coolant flow and leading to overheating.

Gates uses a construction method that reinforces the hose against pressure and vacuum fluctuations common in cooling systems. This helps prevent premature cracking or swelling, which are typical failure points for older or lower-quality hoses. Having the correct molded shape means you won't have to fight with a hose that's trying to bend in the wrong direction during installation, making the job smoother.

When you're replacing your coolant hoses, it's often a good idea to replace both the upper and lower hoses at the same time, along with your thermostat and coolant. This Gates hose is a well-built replacement designed to get your Malibu's cooling system back in reliable working order.
