Toyota Tundra Heater Core

You may drive a Tundra, but you don't want the inside to feel like frozen wastelands because the heat isn't working. If your heater is on high but blowing cold air, or your foggy windows won't defrost, it's time for a new Toyota Tundra heater core.

The heater core is a series of tubes that heat your cabin temperature system. When the heater core has a leak, the heat escapes and doesn't make it into your cabin. Other signs of faulty Tundra heater cores are the sweet smell of leaking coolant or a puddle on the floor of your passenger side.
