What is the primary function of this upper coolant hose?

This hose is part of your vehicle's cooling system. It allows coolant to flow from the engine's thermostat housing to the radiator, where it can be cooled down before circulating back into the engine.

What material is this hose made from?

The hose is constructed from EPDM rubber, which is chosen for its ability to withstand high temperatures and resist degradation from engine coolant.

Should I replace the lower radiator hose at the same time?

It's often recommended to replace both the upper and lower radiator hoses during the same service. Since they are exposed to similar conditions, if one is failing, the other is likely nearing the end of its service life as well.

Product Details

This is the upper molded coolant hose for your 1997-2003 Chevrolet Malibu with the V-6 3.1L engine. It connects your engine's thermostat housing to the radiator, allowing coolant to flow and keep your engine from overheating. Over time, these hoses can become brittle, crack, or swell, leading to leaks and potential engine damage.

Gates makes this hose from EPDM rubber, which is known for its resistance to heat and coolant degradation. It's molded to the specific shape needed for your Malibu, so it fits right without a struggle. This means you won't have to fight with it during installation, and it will sit correctly to ensure a good seal against the fittings.

Replacing a coolant hose is a pretty straightforward job for most DIYers. It's a good idea to replace both the upper and lower radiator hoses at the same time if they're original, as they often fail around the same mileage.
