No body lift...and to answer the question it did fix my problem...my ad blows cold on idle now...and my kon seems to run a little smoother too. Also, a good way to test your fan clutch is while the truck is running try to stop the fan blades with a rolled up newspaper or just a roll of paper...kinda like when you were a kid stopping a ceiling fan with your hands...if it stops or slows to a near stop then its probably bad....if it mangles the newspaper beyond recognition then you probably don't need a new fan clutch. FYI mine was so bad I could not only stop it, but spin it backwards with the engine running....lol
