What is a heater hose?
Your car’s heater hose is responsible for transporting excess heat from the engine compartment in the form of heated coolant from the engine’s cooling system to your heater core, which provides warmth for passengers in the vehicle’s cabin.
How do I know if my heater hose is bad?
The first thing you’ll notice is that no hot air is coming from your heater vents. If the issue with your hose results in a leak, you will soon notice the following:
Dashboard alerts that your engine is overheating
Leaking engine coolant from the heater hose
Coolant puddles or pools under your vehicle
Coolant odor when hood is open
Steam rising from under the hood
How often should heater hoses be replaced?
Typically, heater hoses and hose clamps should be replaced once every four to six years. This translates to roughly every 50,000 to 100,000 miles.
Keep in mind: Every manufacturer specifies a different age limit for their heater hoses, so be sure to consult your owner’s manual or speak with a certified mechanic.
Can I replace my heater hoses myself?
If you want to save money on repair costs and replace your heater hoses yourself, you need to be confident in your auto repair and DIY skills. You’ll need to be equipped with a heater hose repair kit, along with new engine coolant (antifreeze), new hoses, and safety goggles.
Replacing this part can be challenging if you’re not prepared. For the average car owner, we recommend visiting an auto shop and letting a trained mechanic perform the job.
