    93 GM engine heater location

    I installed an engine heater inline with the lower radiator hose but it doesn't seem to heat up the block at all. Is the location different for these motors?

    You can buy an aftermarket block heater that replaces a freeze plug. I am sure that would probably be a good way to do it. However I have never done something like this so I don't know. Although I had a 1990 F-350 with the 7.3L Diesel and I believe it was in freeze plug but don't quote me on that.
