As temperatures drop, your car’s heater becomes more and more essential. A well-maintained heater not only keeps you warm, but it also helps keep you safe on the road by defrosting your windshield. Nobody wants to be stuck in the cold, so here are some tips to keep your car heater running well through the long Rexburg winter.
Check Your Coolant Levels Regularly
Your car’s heater relies on the engine’s cooling system to work. Coolant, also known as antifreeze, circulates through the heater core and creates heat for your car. Low or contaminated coolant can make your heater perform poorly or fail. Check your coolant levels at least once a month and top it off with the correct mixture of coolant and water, as specified by your car’s manual.
Keep the Heater Core Clean
The heater core is the heart of your car’s heating system. Over time, it can become clogged with dirt or sludge, which restricts airflow and therefore reduces the amount of heat it can produce. If you notice reduced heat or a musty smell, have your heater core inspected and flushed by a professional.
Inspect the Thermostat
The thermostat regulates engine temperature and ensures the heater gets hot air. If it’s stuck open or closed, your car may take too long to warm up or overheat. Signs of a faulty thermostat include fluctuating temperature readings or an engine that never warms up fully. If your thermostat is faulty, it’s a good idea to get it replaced.
Maintain Your Blower Motor
The blower motor is what circulates warm air through your vehicle’s vents. A failing motor can leave you with little to no heat, even if the heater core is functioning. Listen for unusual noises like squealing or rattling when the blower is running. If you hear anything out of the ordinary, get that faulty motor replaced so that you can stay warm.
Change the Cabin Air Filter
The cabin air filter traps dust, debris, and pollen to keep the air inside your car clean. A clogged filter can restrict airflow and reduce the efficiency of your heater. To avoid this, it’s important to replace your cabin air filter every 12,000 to 15,000 miles, or as recommended by your vehicle’s manufacturer.
Check for Leaks
Coolant leaks are a common cause of heater issues. Leaks can occur in hoses, the heater core, or other parts of the cooling system. A coolant leak can lead to insufficient heat or even engine damage. Look for signs of a coolant leak, such as puddles under your car, a sweet smell in the cabin, or frequent drops in coolant levels and address leaks immediately.
Don’t Ignore Unusual Smells
If your heater creates a burning, musty, or chemical smell, it could mean there is a problem. Burning odors may mean electrical issues, while musty smells often suggest that there is mold in the vents or heater core. Pay attention to unusual smells and have them investigated by a professional to prevent further damage or health hazards.
Warm Up Your Car the Right Way
Many people think idling their car for a long time on cold mornings helps the heater work better, but this isn’t necessary. Modern engines warm up faster when driven. The best way is to start your car, let it idle for a minute or two, and then drive gently to help the engine and heater reach optimal temperature quickly.
