Brrr! Here’s What You Need to Know When Your Vehicle’s Heating System Fails

Today’s vehicles have some fancy-schmancy heating-system features. You can be one temperature while your passenger can be a different one, for example. Vents for the people in the back and heated seats also add to the luxury of making each passenger as comfortable as possible. But sometimes something goes awry with your heating (or cooling) system. What then?
Here are some ideas you can start with in an attempt to get to the bottom of the issue.

Heater core

This small part has a big job. Heated radiator fluid is diverted through the heater core where it’s dispersed by a fan. The fan blows the warmed air through your vehicle’s ductwork and then into the car’s cabin where it warms you and your passengers.

If you notice a problem with your heater, the first place to check is the hoses that make up the ductwork. Another possible issue could be that the heater core itself needs to be replaced. If you don’t feel any air moving at all, the problem could be the fan.

Exhaust systems and ducts

A clogged exhaust can cause your vehicle to overheat – even in the coldest weather. This is a fairly serious issue and will require you to get in touch with your trusted mechanic right away. On the other hand, If the issue is clogged vents, you’re in luck. You can vacuum them out, clearing any debris that could be causing things to get stopped up.


One of the most important elements of your vehicle’s heating system is antifreeze. Here’s what you need to know about this key component.

What is antifreeze?

This colored liquid is an engine coolant. It is mixed with water and regulates your car’s engine during extreme temperature – hot or cold. As the outside temperature begins to drop from warm to cool and then cold, antifreeze gets pumped through the engine block to keep the engine’s operating temp even. Antifreeze also helps to prevent corrosion.

How often does your car need fresh coolant?

Always defer to your owner’s manual instructions, but it’s generally recommended that you have your antifreeze flushed and changed twice a year – once before summer heat hits and once before the winter gets cold.
