    I know alot of guys on here are from warmer climate areas, but. I bought this tahoe 2001 5.3L from down in the states. I can't find the block heater cord any where and it was -20 celcius last night. I know some vehicles don't have a block heater, so, where abouts on the engine do I find where it goes and will it be hard to install? Thanks.

    It might not have one. Check behind the headlights.

    Yeah, you're not going to have one. On a gas truck, you have no real need.

    The cords are easy to hook and unhook. Just climb underneith the cab close to the front wheel on the driver side. Look up and there should be a little kidney shaped socket close to your cats or just upstream from them close to the intake manifold to the right (same side as the block). If you still cant find it ill take a pic tomorrow cz I'm in school til 7:30 tonight.

    The dealer ship wants 45$ for a new cord but most autopart stores sell them for about 20$.

    Is that location only on NBS or are the hook ups the same for OBS?

    Sadly enough I never knew what that plug was for but never the less I have one also.

    We can get down to -45 celcius with a wind chill in the winter here. No block heater means no starting.

    Research wind chill...it's junk science, Ibut I understand what you're saying. What type of vehicle are you talking about having a hard start? My brother-in-laws Silverado would start right up for us -15 below zero Fahrenheit. About -26 celsius. Poor batteries can really toughen things up. And carbs can be PITA, too. And most of these engine block heaters only do the coolant, and not the oil, which is an even bigger concern. And it has happened where a code is thrown ( DTC P0116 ) on fuel injected models when the computer notices a larger differences in temperatures.

    Its a 01 tahoe. Your right about not warming the oil, and once I get the block heater figured out I'll add a pan heater as well.

    Cool. There's some places that sell ones that have magnets to adhere to the oil pan. Make sure you have a lower weight oil. The regular coolant heaters are installed through the freeze plugs on the engine block.

    I installed by my self a block heater in my GMC 5,3 2006 and there is a
    plug in a threaded hole, driver side , below spark plug 7.
    It wasn't so very diffucult and I strongly recommend block heater, but never
    even heard of anyone using pan heater, and I live in northern Sweden.

    Google it and see if anyone ships to Sweden. Used to keep the oil "warm." While oil won't freeze into a cube, it doesn't flow as well when cold. And even if it's 100* outside, start-up is the hardest time for an engine. Slower flowing oil doesn't help, either.

    Is all the coolant going to spill out when I install the block heater?
