My 08 6.4 had the rapid heat in it....I didnt think much of it on that truck and didnt get my new one w/ it. Little did I realize that it actually worked pretty darn well lol....it took a bit but the truck was always pretty warm after 4-5 mi no matter how cold. A few weeks back it was about 2 degrees out....on my 20 mi trip into work I froze my arse off.....well not really I had toasty buns from the seat heater but all else was cold! My coolant gauge hardly came off the needle and ill let u guess how cold the cab was lol.
I know it requires the hd alternator, but ive got the snow plow prep pkg and know it has a hd alternator (im guessing the same alternator
?) So is there a way to add it? Thanx!
