All vehicles with an automatic transmission have a built in cooler in the radiator regardless. RPO code "KNP" is HD cooling and "Z82" is the HD trailering provision. Look these codes up in your glove box to see what your truck has. You should be able to see the optional HD cooler through the grill it sits in front of the AC condenser and is about 8" x 10" in size.
