So, has anyone had it done after delivery?

As I stated above I have installed the block heater for the H3 after getting it at the dealership. What kind of dealership are you talking to about installing this??? I have herd people on here berate dealer techs and being one myself usually felt defensive but if your dealer techs can't access GM Service Information and figure out how to install a block heater then I feel sorry for you. If they can't seem to get it done give them this... It is procedure for replacing the heater but is the same for removing plug and installing heater. Heater screwws right into side of the block.
