  1. USE for your LS swaps.. Not us. Edit would not let me correct title

    I am going to be using my original 3 core radiator. What options do I have on water hoses and water neck do I have. Did you tap out your heater hose nipples also? Right now I have the truck water neck but its removed in the pic.

    If you're using electric fans, I've been making tapped upper radiator hose aluminum adapters for use with a BMW dual temp fan switch-makes it easy to use the 14mm switch.
     
  4. Yea, Im using a 1997 Trans am LT1 dual fans.

    I'm using a 1.5" hose adapter with a drilled/tapped 14mm bung for using the BMW switch-I'll gets some pics of the setup shortly.

    The NPT size are 1/2 and 3/8.

    As for the water neck I use an LS1 neck but it looks just like the truck neck and this is the lower hose I used.

    Now this hose will only go on one way and work.

    I bought that lower hose on eBay for $14 shipped. Not too shabby. It was advertised as a hose for a Mazda, but the picture was clearly the hose I want, so either I got a decent deal or they are sending me the wrong hose, lol.
