Your vehicle’s heater core is a critical component of its climate control system. When it’s in good working order, it’ll keep the cabin of your ride warm and comfy and your windshield free of fog or frost. But when your heater core goes bad, you may experience little or no cabin heat, coolant leaking on your vehicle’s floor, or your windshield may fog up when you turn the defroster is on. The good news is, we’re here to help with a wide selection of stock replacement heater cores that will restore your vehicle’s climate control system to peak performance.
Resembling a small radiator, the heater core is located inside the HVAC plenum which is usually tucked behind the dashboard. Replacement cores are commonly manufactured from aluminum or a combination of brass and copper, and most feature OE inlet/outlet ports and factory mounting locations for a simplified installation.
Whatever you drive it’s a good bet we have a heater core that’ll bring the BTUs back to your ride’s heating system. You can shop OE-quality heater cores from trusted brands like Hayden Automotive, Mopar Replacement, ACDelco, Motorcraft, Crown Automotive, and many more.
