    I just bought one of these and my question is how should I mount the cooler. Should I put the fittings on the bottom or on the top. It is 8.5X22X1.5. Also the fittings are female 3/8 inverted flare does anyone know of any 90 deg fittings for that style?

    Thanks

    I mounted the same cooler with the fittings pointed down. As for the 90 degree elbows, just go to the local automotive store.

    Pointing them up makes it cool better. Fluid stays in a little longer.

    Just curious, how does pointing the fittings up make the fluid stay in the cooler longer? :confused:

    I always have coolers fill from the bottom and exit from the top, that way the whole cooler is sure to be filled and used. With a plate type cooler like the one posted, it is possible to only have a part of it fill if it is mounted with both fittings down. With both fittings up it is more likely to fill entirely, but with it filling from the bottom and exiting from the top it has to fill the whole cooler.

    That cooler is 22" I do not know if I have enough length to stand it on end like that. I think it is designed to mount length wise in front of the radiator. Does anyone have this cooler?

    The cooler has to be full for fluid to exit. The fluid cavitates in the tube to a degree. Cavitation in the full cooler makes the fluid get exposed to more of the cooling surface.
    I kinda said it wrong the first time.

    I run this cooler on my 56. My instructions showed it mounted with the fittings on the bottom. I figured that since the factory coolers usually have the lines hooked to the bottom of the cooler I'd hook it up that way. I was worried about air getting trapped in the top of the cooler too but it seems to work fine. Never had it get above 170, even during the summer. I think it only reached 170 because of the external thermostat.

    I just checked on the Dana site and they say it doesn't matter if the fittings are mounted on top, bottom or on the side. So I'd mount your cooler any way you'd like to as long as you get as much of the incoming air stream as possible. If I get home before it gets dark tomorrow I'll get a shot of the way I mounted mine. You're going to like the way this thing works!!!

    Thanks for the input looking forward to photos. I grew up down in FL so I know how hot it gets down there.
