3 Signs Your Car Has a Bad Heater Core

The average person keeps their car for almost seven years. This means it’s normal to experience some mechanical issues along the way.

Though most issues are minor, some are a bigger inconvenience for drivers than others. A bad heater core is one of them.

The sooner you can get it fixed, the better. So, how can you tell if your heater core is acting up? Here are a few key signs to watch for.  

1. You’re Not Getting Heat

One of the most sure-fire signs that you have a bad heater core or a heater core leak is the lack of warm air coming into the car’s cabin when the heater is on full blast. When the heater core is leaking, the air it heats up starts to leak out, too.

This results in a lack of warm air coming through your vents when you turn the system on.

Keep in mind that the problem may be due to a fault in your heater’s motor. Regardless, the best thing you can do is get it checked out by your preferred mechanic.

2. The Windows Keep Fogging Up

One of the biggest benefits of a heater core is that it helps keep your windows free of fog. If you notice that the windows keep getting fogged up or start battling condensation on your commute home, you likely have a heater core problem on your hands.

The coolant circulating through the core gets incredibly warm. If the core starts to leak, the warmth from the coolant can start to seep inside your car. That heat and moisture will create tons of condensation on your windows, making it hard to see as you drive.

The only way to get this fixed is to work with an experienced mechanic and let them assess the damage. These services and consultations are affordable, so don’t panic about ruining your budget.

3. You’re Replacing the Coolant Often

Coolant helps keep your engine from overheating. When you’re dealing with a heater core leak, you’ll typically have to refill the coolant every few days.

Pay attention to the coolant levels of your car. If you’re constantly having to refill it or your car keeps overheating because it’s out of coolant, you likely have a bad heater core.

Getting your car inspected quickly is vital. There’s always a chance that the engine suffered damage when it overheated. Your mechanic will be able to let you know what’s going on and make the necessary repairs so you can get back on the road.

Watch for These Bad Heater Core Symptoms

As a responsible driver, it’s normal to worry about the condition of your car. Keep an eye out for these common signs of a bad heater core and you’ll be able to keep your car in good shape.

If you notice anything that seems off or think your heater isn’t working normally, get it checked by your mechanic as soon as possible.
