    Unhappy Block Heater?

    Imported my vehicle (1995 Deville) from the US to Canada.

    I assume the vehicle does not come all ready equipped with a block heater?

    (Just called my local dealer to inquire of the cost...forget the cost ($500-600), the dealer said it would require two block heaters...does not sound right?)


    Thanks, Alex

    If you have a Northstar (update your profile to show your car, model, engine) there are 2 block heaters - Calrods which attach to the block sides and join at an underhood mains plug.

    Not sure if it's a 4.9

    Talk to rippypartsmaster, www.rockauto.com, or www.gmpartsgiant.com

    Actually, I've owned two 92 eldorados and they both had 2 block heaters each.

    Re: Block Heater?

    While I have used the block heater on my two of my Oldsmobile's 1 diesel, 1 gas. It uses only one (307), and works great! I know the pain of removing the freeze plug and installing and praying it doesn't leak. Which leads me to thinking of using a tank heater which costs just as much, but is easier to install and takes up a little more space. I too am thinking for use on both of my 4.9L and 4.6L Caddy's. Might check out the tank type?

    Alex: I have block heater in my '02 SDV, I live in Canada and I have never pulled them in. This car starts so well, there isn't any need for them.

    How cold does it get where you live? I've had -24F cold starts, and +11 cold starts the night after -40F, and she runs fine. I just let her warm up to idle.

    Re: Block Heater?

    FWIW the 4.6 Northstar uses 2 Calrod elements bolted to the lower block sides. The electric cords Y into a plug that is either coiled up on top of the engine or hangs out the grille.

    It does not use a coolant heater because, given the setup of the cooling system flow path, there's no place to install a hose or tank convection heater.

    I've used an inline heater from NAPA on several vehicles(no caddys though). easy to install and cheap.
