A heater hose that has cracked or swollen can let coolant seep out, and a coolant level that keeps dropping, checked with the engine cool, can be another sign. Before you replace the hose, rule out a loose clamp or a leak at a nearby fitting or the heater core, since a leak there can look like a failing hose.

This Gates heater hose is a direct-fit replacement for the lower heater position on the 2012-2020 Chevrolet Sonic.
