    Bending aluminum tubing sucks. You'll need a port on the water neck to let air escape. Burp it!

    Be like a brake bleeder screw ... open it up, pressurize the system somehow to blow the air out, then close the valve or cap or whatever when the fluid is solid.

    I just did this not long ago on my rig. Its a trail only rig. I used sch40 1 1/4" water pipe. I went that route because its cheap and it should hold up to abuse very well. Im using the stock radiator mounted behind my cab with 2 taurus fans. The one time that I have wheeled it I only needed one fan on, mostly cuz the other one fried. It stayed at 180-190 the whole weekend. Well see how it holds up during the summer.

    As far as what everyone is saying about burbing the system. If you have air trapped in the system it will over heat very quickly. When I fill mine I have to undo the upper hose at the motor and stick a screw driver in there to let air out. This has worked the last 2 times I had to refill it.

    I dunno if that would hold up. If I had time I would graft on another radiator fill cap into the hardpipe. That way I could fill and burb at the front. Summit sells something like it that you can put in with rubber on each side, but I dont have that kind of room.

    Another benifit of doing this was that I could fit my winch behind the grill.

    Basically for burpin the system, all you need is something you can open up at the highest point at the engine. If your water neck is the highest, you can find a waterneck that has a port in it already. Screw in a plug. Loosen it to let air out and call it a day.

    If your hose goes up from there, you can put a steel tube in at the high point with a NPT fitting and the same plug. Either one is pretty easy to do.

    Start the engine up and have the port open, When water starts coming out close it up.
