    is there a way to tell which engine a truck has by looking on the outside of it? im looking for the difference between the 4.0 and 3.0. does the emblem with the leaf mean its a 3.0? thanks for any help.

    Decoding the VIN# will definitively tell you engine size. 8th digit... U = 3.0. X = 4.0 OHV. E = 4.0 SOHC.

    If it's got a leaf on the tailgate, the leaf emblem means flex fuel, which also means 3.0. No other flex engine was available on the American Ranger. I believe 3.0's have valve covers which say "3.0 V6" molded into the plastic on newer models. Older models have some really neat looking aluminum valve covers that say "3.0 V6".

    I believe newer 4.0L OHV's have "4.0L OHV" molded to the top of the plastic intake. Older models have aluminum intakes without any labels.

    4.0L SOHC replaced the OHV in 2001. The blantantly obvious engine cover says "4.0L SOHC". But those can easily be removed. Other visual identifications include a short intake tube(in comparison with the other engines), a sticker on the side of the driver's side valve cover with info, really wide 10" or so aluminum heads. I know this one fairly well and can go on for days on it's visuals but I'm choosing not to. lol.

    Hopefully this helps.

    the leaf emblem is also 3.0 only, but only on '00 and newer 3.0 trucks. it means you can run E85 flex fuel.

    edit: whoops i missed this above...

    I tried to go off this but on my 02 the 8th letter is V. What is that supposed to be?
