    Can it be done? Has anyone done it? If it has been done, what mods are needed? Any and all help is greatly appreciated. Thanks in advance.

    See Ya,

    It could definitely be done if you changed the core support, otherwise, come up with a way to fasten it down.

    I believe that it's wider than your stock one.

    I was going to try it but the radiator I was going to use turned out to be junk.

    Actually, I dont believe you need to change the core support. My 6.2 has two threaded holes for a smaller 3 core radiator mount and every gas powered truck ive ever seen has the two threaded holes for the bigger diesel radiator. Im sure it would just be a matter of moving the upper tie down and getting the correct mount for the bottom and then a new shroud to match the bigger radiator.

    I'm using the stock 6.2 radiator and shroud w/my 350. It is wider, and I've noticed the same thing about the mounts. Radiator hoses is the other problem, the inlet and outlet are bigger than the gas radiators, and the upper hose has to be longer. I think I used a 350 hose on the bottom, and the top hose is for a '72 Firebird w/ a 400 motor. I had to stretch both hoses onto the radiator. I've also seen guys splice two hoses together for the top one, this may not be a bad way to go. Maybe a diesel hose and a gas one, spliced w/one of those exhaust adapters (bumped up on one end).

    I had this setup in my K3500 w/ a 350 Swapped in easily. I believe I reused the bottom and top supports. Used the original bulkhead

    Hey Kieth,
    Steve_87k5 sent me this message once when I asked about the same thing

    "
    The diesel rad has 2 internal coolers. One for ATF and one
    for engine lube oil. Also 2 bungs for sensors. When you connect your
    engine oil to the cooler, be careful. The tank metal is very thin and if the
    hoses vibrate and hang out too much it will crack the tank.

    I custom made a 90 dergree fitting so the hoses go straight
    down and don't weigh on the tank. I used
    oil fitting 3/4-18 UND #8 Weatherhead tubing nut and silver soldered to it
    and used O ring to seal to the bottom of the rad bung.

    rad hold down bracket R GM 14039950 bracket
    rad hold down bracket L GM 14039949 bracket
    rubber mounting pads GM 6264100 pad

    My rad is model IR2098

    Good luck and thanks Steve...

    Hey, thanks for all of the help guys. From what I am getting here is that it can be done and is not to hard providing you have all the supports and shroud and such.

    Sounds good. Anybody else have any info on this swap?

    See Ya,
    Keith
