Hi.. Is it necessary to have a block heater in my 2016 diesel. I live in co. So we do have cold winters. My old 2004 diesel had a block and made starting easy... Jim2007
As stated, you already have the heater, you likely just need the cord. In my area of the country its not *needed*, however it does help the truck warm up faster... but more importantly the heat comes on faster when its plugged in.
If I know that I will be driving the truck with the family that day, I might plug the truck in the night before or in the morning that day. It only costs a few cents of electricity and makes us so much more comfortable.
