A hose that leaks coolant, cracks, or feels swollen or soft can be due for replacement, and it should only be inspected with the engine off and cool. Before you replace it, rule out a loose clamp or a leaking fitting at either end that could be behind the coolant loss. If the hose is the cause, this one replaces it.
