If you haven’t already checked your vehicle’s heater, now is the time. With the cold winter days upon us, preparing your heater for the winter is extremely important to not only avoid that miserable ice box feeling when there’s no warm air blowing, but also to prevent possible hazards while driving due to the defroster not blowing warm air to your windshield to eliminate ice and fog. This article will discuss how to prepare your vehicle’s heater for winter. If you have any questions or want to have your vehicle’s heater inspected, contact Asher Automotive today for all your winter service needs.

Common Car Heater Problems

If you turn the dial to turn your heat on in your vehicle and there isn’t any hot air, there are a few issues that could be affecting its performance. Before going to start replacing parts, check your owner’s manual and call Asher Automotive if you need any assistance.

Some of the common car heater problems that occur include a worn out thermostat and restriction preventing flow of coolant. Contact Asher Automotive today if you believe one of these issues may be occurring in your vehicle.

Thermostat is Worn Out

If when you turn the heater on in your vehicle, the temperature of the air coming out isn’t hot, it could be an issue with the vehicle’s thermostat. The thermostat may be preventing the coolant from getting warm enough to heat your vehicle and it will probably need to be replaced.

Restriction Preventing Flow of Coolant

If the thermostat in your vehicle is working correctly, then you probably have something blocking the heating lines. Sediment build up can occur in the heater core, which means the line will need to be flushed.

Heater Servicing

It is important to check your vehicle’s owner’s manual to find out when you should have your heater serviced. Servicing is recommended in most vehicles at 30,000 miles. To help you complete this task you can purchase a flush kit.

  • Flush the radiator
  • Check the heater core and hoses for sediment build up
  • Replace the thermostat
  • Refill the radiator with antifreeze. (Check the owner’s manual to see what the right mixture is for seasonable temperature changes)

Signs of Heater Trouble in Your Vehicle

It is best to avoid car-heater problems from occurring altogether. Pay attention to the following signs of impending heater trouble:

  • Hearing a chirping or screeching sound when you turn on your car heater suggests a worn-fan motor bearing. Motor failure will quickly follow.
  • If your dashboard heater-control lever is unusually stiff, this could be a sign of a sticky or inoperative heater-control valve.
  • Accumulation of moisture inside your care even with the defroster is running, then your car’s heater core—a miniature radiator—may be leaking.
  • Does your vehicle’s heating system operate inefficiently? Heater and defroster duct hoses carry fresh air into the system and warmed air to locations beyond the heater core. If these duct hoses leak, your heater will not efficiently warm your car or defrost your windows.
  • If your heater only blows cold air, a leaking heater hose (which carries your system’s antifreeze) could be the culprit. This can leave your stranded on the side of the road.

 

A properly functioning heater in your vehicle will ultimately keep your comfortable during the cold winter months and keep your windows clear, which is important for safe winter driving. So knowing the signs and paying close attention to your car will keep you from possibly being stranded on the side of the road in the cold later on.

  1. This is some great information, and I appreciate your suggestion to flush the radiator every 30,000 miles. My husband and I bought this car a while ago, and I think it’s been more than that since we had our radiator flushed. We’ll definitely look into having that done in the near future so everything stays in good condition. Thanks for the great post!
