Yesterday I became the proud new owner of a '99 Tahoe LT. After trading in a diesel VW New Beetle for it my wife and I are practically dancing around for joy to be back in American steel. I have the original window sticker indicating the "heavy duty trailering equipment." I've checked the option codes in the glove box and compared them to this site http://www.automotive.com/1999/12/ch...ges/index.html
which indicates that the tow package (Z82) should include the tranny cooler (KNP) and oil cooler (KC4). The transmission cooler code is listed (and I'm guessing it's the little radiator in front of the usual one) but there is no code KC4 listed for the oil cooler. I'm wondering if there is possibly an alternate code number for the oil cooler, how I might identify it on the truck and if it is necessary for my use. I'm towing a 5000lb pop-up and expect the most extreme conditions to be hauling it in the Smokey Mountains in mid-summer. Any help would be appreciated.

Thanks, and glad I've arrived

Joe
