Engine coolant HEATER?

    I was reading through my truck's owners manual this afternoon (not much else to do w/o snow :cry:), and came across a section outlining how there is an engine coolant heater on the 6.0L V8 Engine. Do all the trucks have it? If not, what's the code for it? I was looking around in the engine for it for a while and couldn't find it (if my truck even has it I'm not sure). Anyone know if all the trucks have it,a nd if so, where it's located (the plug)?

    Thanks,
    Matt

    I have a 03 and it is tucked up on top of the frame in front of the left front tire. It is wrapped up and a little hard to find. My Dad has a 05 Jimmy and it took me a while to find his block heater plug also. Take a look through the drivers side front wheelwell and you should find it.

    So they all do have it then?

    Is it a block heater or an actual coolant heater? Would it do harm to leave it plugged in say overnight even if the temp is at like 25*F?

    They are only 1500 watts, so no harm will come by leaving it plugged in.

    It was - 30F last week and I had to plug mine in, usually I don't except the starter drive has been disengaging. It would have started if it would have cranked over.

    @ 25 degress it is not needed and would be like leaving a hair drier plugged in all night.

    Or plug for 1or 2 hour before you ready to go it. Instead overnight that would cost close 10 dollars or more for that.

    Okay, I went out to look for it, couldn't find it. Can comeone take a pic and point out exactly where it's located? Is it actually on the frame itself? How can I get to it (from the top, underneath the truck?)? Is it just wrapped, or is it in a little "box"? If someone could landmark it by giving it's position relative to the PS pump etc, that'd be great. Is it before or after the "bend" in the frame (where it bends down in the very front)?

    Thanks,
    Matt

    Also- do all 6.0L's definitely have it, or is it like an optional item (with a code)?

    No, they don't all have it, most don't and its a option on a gasser. You don't need it on the gassers.

    Hmmm, that's interesting, in the manual, it says it as if it's on all of the 6.0L's. Is there a code in the glove box for it so I cna see if my truck has it?

    I don't know the code but the manuals for my '99, 02, and 07 6.0 Chevies all eluded that they came with a coolant/block heater but none of them had it. If yours doesn't have one, you can add one really cheap.

    I'm not sure if GM has changed the RPO# but on my 94 GMC the "HEATER, ENGINE BLOCK" was code K05. I hope this helps. It is my understanding that it is an option on the gassers.

    I agree but if engine is cast iron so need heater. My 1979 f150 have engine it 4.9L 300 it got forever to warm up. We change thermoset to 190 degree but I think it would help fast if have heater on it but I am not sure how much it cost but it pretty expense like 60 dollars.

    K05 is the correct option code for the block heater. And it is an option on the gas engines.

    It is an actual block heater that's threaded into the block on the driver side above the oil cooler outlet.

    I believe that many of the Canadian destined trucks that dealers ordered got the block heater, so that may be why many guys in the northern climates find their 6.0's do in fact have the option.

    My truck was made in Canada, so I'd assumeit'd be possible it could have it. My truck came from Rochester, NY. Anyhow, can someone give more specifics on how to locate it if it's there?

    Easiest way is to look at the RPO option decal in the glox box for the "K05" option code. If it has the heater, it'll be there on the decal. Won't even need to get your hands dirty..:)
