    I just purchased a 2001 Silverado with the 6.6 Duramax. I'm can't seem to locate the plug I would use to warm the block when the weather turns cold. From what I read it should be located near the power steering. Is it possible this truck didn't come with this option? At what temp would/could this become an issue?

    Diesel block heater plug locatioon

    Water freezes at 32 deg F. Antifreeze will let you go lower. If you get consistent temps in the 30's I'd say that a block heater is cheap insurance.
    Here are a couple of images of the cord. It will be zipped tied in the engine compartment topside.

    If you live somewhere below freezing for long periods of time then you need a block heater. People around here have never seen snow chains let alone a block heater plug.

    It should be on the right side of your engine, a pretty long chord, i say around 4 feet or so. You also can buy magnetic block heaters. Ones that are just magnetized and they will stick to your block, or your oil pan. and then you just plug it in.

    a lot of times when you buy a truck used the previous owner already re routed it for those ive seen them zip tied near the tow hook or else hidden behind the wheel zip tied to the fender liner or upper control arm

    Mine was on the left side zipped tied. I hate how its not long enough to come out the grill. We use ours every night so I wish it were longer.

    Even if my truck isn't plugged in at -15 it fires right up. I feel bad if I forget though. Remember to unplug it before you drive off though. I forgot one time:eek:

    I found mine...

    My second battery is on the passenger side at the fire wall. If your truck is like mine then follow the positive cable down and it will be tied up to the cable right beside the finder. Hope this helps

    You should bring them to Utah, we'll teach them to drive in the snow. :lol:

    I am pretty certain the engine block heater is an extra cost option. So some used vehicles may or may not have it.
    Also you only really need it for extreme sub zero temperatures. -20, -30+

    My Dad's Powerstroke would disagree with you. He came to visit, it was only around -2, & his truck would not even turn over lol.

    He had to plug it in. Poor Ford:rofl

    Not positive but my 08 didn't come with one and my bro in-law who works for a GM dealer said it didn't come with one and here in MD I wouldn't need one.

    I would just about be willing to bet money there IS one... and yes, you probably wouldn't need it......

    According to the brochures I have, the heater is an option that you have to order on the side. If you bought it off of the lot it might have the heater installed but other wise your're looking to add one on.

    I thought It all depends on which vehicle and which year and which packages the vehicle came with. In the past some vehicle packages it was standard with the diesel, some it was an option for certain vehicles built in certain years. There are base packages, LS packages, LT packages. So some vehicle builds that come with the diesel may have it standard and in that particular package the block heater is included. For other packages it may not be included. I believe NOW it is included standard with all Duramax diesels but in the past it was not standard and may not have even been available when the duramax first went into production.

    GM has built all sorts of vehicles with all sorts of packages with standard and extra cost options over the years.
    Every vehicle that GM built and got a diesel in the last 10-20+ years I don't think also got an engine block heater as a standard feature no cost option included with the vehicle.
