    The easiest way to find if you have one would be to look at all your freeze plugs along both sides of the block. If it has a heater it would be installed in one of these. They are not all that big, but you should be able to see it & it will have a wire pigtail coming off of it.

    Near the cross-member that goes under the engine would be a good place to start.......

    I have an 03 2500hd D/A. The RPO codes on mine are V10= Cold climate provisions( might be the cold weather bra for the front end) & K05= Heater engine block. I think the cord is tied on the right side near the frame. This truck was purchased new in Menlo Park, Ca. I have never had to use the heater, but I did locate it shortly after I bought it.

    Hope this helps.

    I just did several of these in our fleet. The heater cord is zip tied up under the right side battery tray. There should be a big bundle of wires under the tray, they're all black and hard to see. There should be just enough cord to make it to the front grill if you run the cord right.

    When I had my truck in for it's oil change I asked them to check and they found it on the Pass side of the block and brought it out next to the rad. Scott, thanks, when you say RIGHT side do you refer to it when sitting in the cab? I always thought when looking under the hood the RS was on the drivers side when standing in front of the truck.

    Left and Right should always be referred to from the vantage point of sitting in the Drivers seat.... It reduces confusion that way...
