    Default Block Heater - Seeking Advice

    I just purchased a 2008 Z71 1500 Silverado, 5.3L V8 Gas/E85 I'm going on assignment in Northern Canada, it's been recommended I get myself a block heater for my vehicle but I don't know anything about my options on this truck. I have read some poor reviews on the OEM heaters for early models.

    Does anybody have any recommendations on what kind to purchase? P#'s would be helpful.

    Where to purchase it from?

    Any help would be appreciated.

    Welcome to the site!

    I live in Texas, about 80% of the population down here has no idea what a block heater is. I grew up in the Northwest and saw a good share, but never had need for one. I assume that you can get one just about any northern-based auto parts supply houses, certainly the dealer could put one on up there once you get there. If I'm not mistaken it's a pretty simple concept overall.

    Found a quick article on some different types of heaters, this is for a Ford, but principal applies universally.

    Greetings and salutations, jgunderson81. Welcome aboard.
    I live in SoCal where block heaters are less common than UFO's. Hey, I've seen Fargo many times, and the Gunderson Clan is supposed to know all about cold weather driving.
    Seriously, the guys who know best what's to be done are the ones where you're headed. The wisdom that says it's wise to hire a local guide when hunting in an unfamiliar environment, also says the local boys may know best what it takes to get thru one of their winters.
    Are we having fun, yet?

    Welcome to the site. Even int he cold temps of New England a block heater is not a bad option. A friend of mine has one on his FordFocus.(*Sorry I had to use the 4 letter word*)
    He loves it in the dead of winter. Says it makes the cold mornings that much easier to deal with. Although the oem parts may have some bad reviews I did some searching for you and had some problems finding an Aftermarket one for your truck. Steve has the right idea though. Up there it would be a more regular item so the price maybe better and availabilty will probably be greater.

    Anyways goodluck in your adventure.

    Default Welcome to the site!!

    How far north are you headed? I lived in Alaska many years ago and made it without a block heater But I donít recommend it. I had a vehicle with a manual choke and a battery heater. But those -40 mornings really sucked and some days I had to ski into work.
    The time of year you are going to make the drive should determine if you put one in before or after you get there. It is not a hard process to put one in just tedious. Iíve put them in a lot of trucks back in the 80ís. If you are driving up there in the middle of the winter get a dealer to install one before you go, but if you leave a decent time of year itís always cheaper do have one put in up there (Supply and demand)
    As for after market differences, itís just a heating element (Toaster) replacing a freeze plug. They should all be pretty close in capability. Good luck, and have fun in the white stuff. I havenít seen snow on the ground in 7 years.

    Block heaters are heaters for your motor block. In below freezing weather you can plug your truck into normal 120 VAC and the heater (think about a regular iron - but not as hot) keeps you motor warm. It makes for easier starts and prevents liquids from freezing. I haven't used mine yet but most likely will this December.
