    How do I know if I have one? My manual tells me where it is but I can't find it.

    Is there another way to know or am I just blind?

    it's an 07 2500 diesel.

    The best way is to just look. It should be pretty obvious if you do have it. Also it should be listed on your codes if it was installed from the factory, but if you didn't buy this veh new, the previous owner could have installed one too, so you really have to look for it to know for sure. The owners manuals are generic. One manual fits all, & just because it talks about a particular option or accessory, doesn't mean it will be on your truck.

    Which # in the code would tell me that? Any idea?

    Sorry man I've never had a diesel or a block heater so I don't know the code. Go to compnine.com & plug in your info. All your codes will be on your glove box lid/console. Just write them all down plug them in & comp nine will decipher them for you. Also you should have a build sheet stuffed between the seat springs that tells everything your truck came with, but they are a biotch to get out in one piece without dissasembling the seat. Like I said it's really easier just to look for it on the engine. It's either there or it's not. I would guess that because of where you live in the far north (so darn cold) it should have one, but maybe it was an oversight by whoever did the order.

    It came from Calgary which is much colder than where I live. That's part of the reason I thought for sure it would have one. I think I will park it inside tonight at my work and check it out thoroughly.

    I would think it should have one too. I live at 43 degrees latitude where it seldom gets below 30 degrees F & they put block heaters in about 80% of the diesels here. I know it has to be worse where you live.

    I have personally never seen a diesel truck that didn't have a block heater.... The cords for them are usually zip-tied up out of the way on the frame....

    I would agree with that, unless it was originally shipped to a warm climate dealer & ended up being exchanged on a dealer trade up north. For the nominal cost involved, I think the factory should put them on all diesels.

    me and a couple of co workers looked last night for half an hour and couldn't see one.

    it must not have one installed, but that makes zero sense to me.

    I am home for a few hours today and decided to put a timer on the block heater so I am out in the -24C cold and looked all over the upside of the truck, also a 2500HD(used) and could not see anything. It is supposed to be warmer tomorrow so I will look under the truck. When you say tied to the frame, where should I first look?

    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...
