A heater hose carries engine coolant between the engine and the heater core, which supplies warmth for the cabin heater and defroster. Signs this hose may need replacing include coolant drips or puddles, a cracked, swollen or soft hose, a dropping coolant level, or weak cabin heat. Other cooling-system parts can produce the same symptoms, so diagnose the cause before replacing the hose.
