Heater Hose buying guide
Why replace this part?
Heater hoses carry hot coolant from the engine to the heater core and back. A split heater hose causes coolant loss, loss of cabin heating, and engine overheating if the leak is significant enough to deplete the coolant level.
Signs you need a replacement
- Loss of cabin heat
- coolant leak inside or under the car
- sweet coolant smell inside the passenger compartment
- engine overheating
- soft or spongy hose texture when squeezed
When to replace
Every 4–5 years or 60,000–80,000 miles. Rubber hoses harden with age — inspect annually for cracks, swelling, or softness at the fittings.
