While it may be August now, the mornings will be chilly before you know it! Located in Silver Spring, Maryland, we are accustomed to the harsh winters that make a fully operational heating system a necessity. Here, we'll delve into the basics of how your vehicle's heating system works, common issues that may arise, and how you can troubleshoot them before visiting our service center.

How Your Vehicle’s Heating System Works:

The heating system in your car operates in conjunction with your vehicle’s cooling system. It all begins with the internal combustion engine, which generates a considerable amount of heat. While the radiator and cooling fans handle much of this excess heat, some of it is harnessed to warm your car.

• Coolant: The engine warms the coolant, which is a mixture of antifreeze and water.
• Heater Core: The coolant circulates through a smaller radiator-like device called the heater core.
• Blower: A fan blows air through the heated core.
• Vents: Finally, the warm air circulates through the vehicle’s vents into the cabin.
• Common Issues:
• Insufficient Warmth: One of the most prevalent problems is inadequate heating. This could be due to low levels of coolant, a malfunctioning thermostat, or a clogged heater core.
• Strange Odors: If you notice a sweet, syrupy smell, it could be a leaking heater core.
• Noisy Operation: Any strange noises coming from the blower might signify a foreign object or a motor issue.
• Troubleshooting Tips:
• Check the Coolant: Ensure that the coolant is at the appropriate level. Insufficient coolant could mean less warm air.
• Inspect the Thermostat: If the thermostat is stuck in the open position, it could be continually cooling the engine and not allowing it to warm-up. In such a case, replacing the thermostat might be necessary.
• Feel the Hoses: Carefully touch the heater hoses that go into the heater core. Both should be warm. If one is cooler, the heater core might be clogged.
• Test the Blower: Listen to your blower motor. Any unusual sounds may indicate a need for inspection and possibly a replacement.
• Smell Test: If you smell something sweet and unusual, it’s best to get your heater core inspected immediately as it might be leaking.
