It gets mighty cold up north her and when the factory cord kicks in at -18 it's just too cold with the wind chill. I just want to buy one that doesn't have the thermometer on it. I though about cutting the outside end off if they want an arm and a leg for a straight through cord, but there is not lots os wire to play with.
Thanks

Need to know what engine you have. From what I can tell, there are 3 engines that you could have.
LM7 (Vin T), L59 (Flex Fuel Vin Z) and the L33 (Vin B a.k.a. HO).
The L33 is Aluminum, the other 2 are cast iron.
