Not sure what brain dead sales manager orders any diesel without a cold weather group.....But mine did! So on to the question lol. If your truck was not ordered with the cold weather group will the engine have the block heater installed from Cummins? I know it used to be that way and all you needed to do was order the cord, is that still the fact? With Stellantis now owning them and as F'ed up as their CEO is who knows now.
