    My brother in law just picked up a 2003 F250 diesel with 40,000 miles on it. After looking at it I noticed that by the front passenger side fog light there was a plug. Do they come from the factory with oil or block heaters? I thought I would ask you guys first before I went tracing down wires. I was also wondering what trans do they use? Looking for a plow.

    The 7.3 Superduties had 4r100 auto, ZF5 manual.
    The 6.0L Superduties had 5r110 auto, ZF6 manual.
    I answered your other question in your other post.

    Yep that is a block heater if it gets below 30 plug it in so it can heat the oil or she might not start

    I have the 7.3 and the oil heater broke. It was 2 bellow last night and it was a ***** to get it started.

    If your engine will not start anywhere near 30*F then you got problems that need to be addressed. Mine has started at -12 without the heater, granted it was rough but it did start.

    I agree . Ive owned a lot of Diesel trucks and only had 1 with 250,000 miles that was hard starting when it was cold. First thing you need to know is if the glow plugs are working (relay) and then if ALL of the glow plugs are working. When my 2002 f250 was a year old with 20,000 miles 3 of the glows plugs had already burned out.
