I was wondering if any of you run in minus zero weather? It was - 40 F today and the rig was freezing inside. I have a cold weather fronton but the hole beneath the bumperisn't blocked off. Iwas wondering if it would make any difference to block off that portion or even changing out the thermostat? I had to put on my cold weather gear just to be comfortable during my trip. Thanks in advance on this, Vern

 

I wouldnt do that, you still need to have some air movement over the intercooler and the radiator.

just plug her up and you'll be good to go

 

the mopar cold front blocks off the everthing. it wraps from the very bottom to the very top, but it goes inside the engine compartment. this is on an '06

 

Move to texas! HA! Today i think it got down to 50 this morning, though we are supposed to get snow on tuesday
