Automotive Heating: Stay Warm During Winter.

When temperatures drop, an efficient heating system becomes essential for your comfort, visibility, and safety. In addition to warming the cabin, the heating system also helps defrost and defog the windows.

If your vehicle takes a long time to warm up, blows cold air, or gives off an unusual smell, an inspection may be necessary. At Pneus Bélisle, our experienced technicians can inspect your heating system, identify the source of the problem, and recommend the appropriate solution. You benefit from professional, attentive, and outstanding service, with clear explanations of any recommended work.

Why Is Your Heater Blowing Cold Air?

Your vehicle’s heating system uses much of the heat produced by the engine. Hot coolant circulates through a small radiator located in the heating system, known as the heater core. The blower fan then distributes warm air throughout the cabin.

If the system is no longer producing enough heat, several issues may be responsible:

• low coolant level;
• a coolant leak;
• a faulty or stuck thermostat;
• a clogged or damaged heater core;
• a faulty water pump;
• a malfunctioning blower motor;
• a problem with the heating and ventilation controls;
• a faulty valve or air duct component.

Because the heating system is closely connected to the engine cooling system, certain problems should not be ignored.

What Are the Signs of a Heating System Problem?

Have your vehicle checked if you notice:

• cold or lukewarm air even when the heat is turned on;
• the vehicle takes much longer than usual to warm up;
• weak or inconsistent airflow;
• windows that are difficult to defog;
• a sweet or unusual smell inside the cabin;
• excessive moisture or fogging inside the vehicle;
• a coolant level that keeps dropping;
• unusual fluctuations in engine temperature.

Coolant loss or engine overheating should be inspected promptly.

Why Is the Heater Core Important?

The heater core transfers heat from the engine coolant to the air that is sent into the passenger compartment.

If it leaks or becomes clogged, you may notice reduced heating performance, a coolant smell, fogging on the windows, or a drop in coolant level.

An inspection can help determine whether the problem is coming from the heater core or another component in the system.

Is Your Heating System Not Working Like It Used To?

It is best to have the system checked before extremely cold weather arrives or as soon as you notice the first signs of a problem.

Don’t wait until you are left without heat on a freezing winter day.
