    IE aluminum rad w/ late model exp tank

    Hey all,
    I got a killer deal on a brand new IE aluminum radiator. I know I have to run the late model 325 expansion tank. In terms of mounting will it all bolt up? I'm trying to search around but I'm not having much luck...

    Also looking at the diagram of the expansion tank on realoem where does hose #4 go to?

    TIA

    #4 is just an overflow drain - doesn't connect to anything.

    You'll have to fab up some mounting points for the overflow tank, the 318is inner fender doesn't have these.

      If you go through my build thread, I have pictures of how I routed my setup (I think I'm using an e36 aluminum radiator with a 6cyl e30 overflow tank.

      Here's how I routed stuff. Looks ghetto but it has held up to 2 years of rallycross, so it works.
