Does steam blow from your dash vents like a smoke machine in a cheesy haunted house when the vehicle heats up? Does the sweet smell of anti-freeze in your interior make you crave a piece of hard candy? Do you fill your radiator more often than your gas tank? Has the EPA approached you about registering your passenger side carpet as a protected wetlands? If the answer to any or all of these questions is "yes" then you are in probably need of a this new heater core.

A note on Radiator and Heater Core Shipping: Due to the nature and size, a radiator may incur small dents and scratches on the cooling fins, tubes and/or tanks from handling and load shifting during shipping. Bent tubes can be easily repaired and dents and scratches do not affect the fit or function of the part. Neither our 60 Day satisfaction guarantee, nor the manufacturer's warranty, cover these insignificant damages.
