Coolant drips or crust at the hose ends, cracks or bulges along its length, or a soft, spongy feel when squeezed with the engine off and cool can mean this heater hose is wearing out. A loose clamp, a weeping heater core or a leaking water pump can also leave coolant around this hose, so find where the leak starts before you buy.

This heater hose is a direct-fit replacement for the 2015 Chevrolet Equinox and the 2012-2015 Chevrolet Captiva Sport.
