Aluminum radiator

    ehauff What? What? What?

    Was wondering if anyone has used an aluminum radiator in thier 2a with a 225 v6? If so who did you use? I took the headlight buckets out for more room but still plan on running some form of headlights. I found a chevy radiator but not sure on the hieght. Any ideas? thanks

    jpflat2a what's that noise?

    most of the ones I have seen are custom made jobs.
    The owners almost always end up removing the inner shroud attached to the grille, and remove the large tube type front x member, and replace it with smaller rectangular tubing. This allows the radiator to be moved forward as far as possible, up against the grille opening, and to be longer with the mod to the front x member. They also retain the stock headlight buckets with no mods, as the rad fits nicley between them.
    I recently was faced with this situation, I was loaned a custom alum job, but decided it was too much effort to install it, as the mods mentioned above would have to have been performed. I redid the 4 cyl rad and had the large cap neck replaced with the smaller std size so I could use a higher press rad cap.
    no real help for you, just what I ended up re-using

    I had a cj3a with buick 225 and ran the stock raditor, didnt even change the side the hose came off, it cooled the engine just fine, never had any overheating problems at all.

    IIRC I think M38 Willys is using an aluminum Fiero radiator on his. Saw it at Tellico looked like a nice setup.

    I have to ask
    how did you connect to the lower outlet?
    I have seen some strange rubber hoses and/or exhaust tubing used for this

    it was a strange mix of tubing but it worked, did not leak and the engine was cool. I bought the jeep like that and when I rebuilt it I left it that way because if it aint broke dont fix it.

    If it's helpful, thank schardein. It's his measurements and engine compartment. :D

    Just a couple notes. The drawings are of my original radiator, think it was stock but not sure.
    I had the builders move the top outlet from the stock location to better line up with my upper hose.
    When they built the radiator, the bottom tank was not odd shaped like the original, it is simply box shaped like the top. This made a tight fit next to the bellcrank mount but worked.
    My fan is low in relation to the radiator. This caused very slight interference with the lower outlet (which was built with a 90 degree angle instead of a smooth bend), even using the smallest fan available, and I wish I had told them to move the lower outlet AS FAR TO THE PASSENGER SIDE as possible. Also, hindsight shows the drain plug should be on the bottom of the tank, probably on the far driver side, for the most convenient use. Its present location also interferes with the fan, I have to use a plug rather than a drain****, and it drains right on the front axle.

    Not to steal the thread, but does anyone have a stock tank with the strange lower curved outlet, or was mine the only one??

    I used a fiero Radiator, with a hodgepodge of hoses. Then I added a universal overflow bottle and it works great. All day long at Tellico crawling in low and it never got above 195. Its also .60 over with a little higher comp ratio.

    I did what jpflat2a said. Cut the shroud out, replaced the tude crossmember in the frame with a piece of channel iron and mounted the stock radiator to the grill. It clears the headlights with no problems. The thing I did different was had a custom 4 row core installed in the stock tanks. It is supposed to give even more cooling ability, and it does work really well. My 225 stays at 180 F all the time. The thing I don't like anymore is having the radiator mounted to the grill. I think the body flew stesses the radiator to much and it develops leaks. I too am curious how others mount thier radiators in flatties with a similiar set up. I got to find something different. It doesn't stay at 180 if there isn't any water in it :D
