Does a Dodge Cummins 6.7l diesel have an engine block heater?

Yes they do. Some do not have the plug on the front but the heater is in the block. If you plan on using this heater, you will need to buy a heater cord from your dealer and connect it. It's real simple! You just remove a cap from the side of the block on the passenger side and then connect you cord to it and fish the plug in end of your cord tothe front of the truck for easy connecting.
