Is your car’s heating system ready for winter?

SPONSORED

There are many items that should be on your checklist when preparing your vehicle for winter, but one of the most important is your heating system.

 

Not only does it keep you from freezing but it’s downright dangerous to drive when your heater isn’t functioning properly because you can’t defrost your windshield without it.

 

Now that temperatures are nearing the frost mark it’s the perfect time to check out your heating and air conditioning systems.

 

The heater functions by way of the engine coolant circulating through the heater core. A fan blows outside air over the fins where it’s heated and blows into your car’s cabin.

 

Check your radiator to make sure your coolant level is adequate and that it’s clean. If it’s low, air pockets can develop in the heater core and hoses, which blocks the heat coming to you, according to automedia.com.  To make sure it’s working, check both the inlet and return hoses after the engine has warmed up. They should feel hot.

 

A heater core blocked with sludge can also affect your heating system. To avoid having to replace your heater core, flush your car’s cooling system regularly.

If your heater heats up but the blower isn’t blowing, have it checked out by a trusted mechanic. It could be a blown fuse, wiring, or even a broken blower motor.

Other causes of a heater malfunction are pinched heater hoses, a weak water pump or a cooling or clutch fan that's over-cooling the engine, according to automedia.com
