    Heater Cores & Seals

    Auto heater cores are devices that warm up the interior of your car. The heater core looks like a miniature version of your radiator, and hot coolant is routed through it. The hot air that emanates from the heater core’s fins is then directed to the passenger compartment via a fan. Heater cores and seals go hand in hand.

    Seals, which are typically made of rubber, are used to fill gaps that may appear in between two surfaces. If there is a leak in your heater core, a car seal is the quickest and cheapest solution to your problem. Sealers contain tiny particles that will expand when hot and plug any small leaks in a radiator or heater core (at one time, drivers would just use a handful of black pepper or even an egg white as a sealer).

    An auto heater core is an integral part of your vehicle. As such, you’ll need to keep an eye on its health. Car heater cores rely on coolant, so always make sure that there is a sufficient supply of it in the reservoir. Also ensure that all hoses and clamps are in their proper places. You can access the heater core either through the dash or behind the firewall beneath the hood of your vehicle when it comes time for maintenance.

    There are a number of symptoms related to heater core malfunction or failure, which are important to be aware of. If you notice that the inside of your vehicle is suddenly foggy, you can count on this being a faulty heater core. This occurs when a leak develops in heater and warm air pours into your vehicle. When this happens, you may also notice the sweet smell of antifreeze, along with greasy buildup on the inside of the windshield.

    The clearest indicator of a heater core gone haywire is that it fails to heat up the car or overheats it even after it has been switched off. If you notice any of these symptoms, it's time to shop for replacement parts. Trust us to stock a variety of heater cores and seals so you can keep your vehicle warm in cooler weather.
