I have a radiator that sits low in the front. I have overheating trouble and would like to start with an expansion tank. Just to make sure there is no air in the system.
Have any of you plumbed one? I saw a Moroso one that has a 1/4" inlet and 1/2" outlet. Where do you run the lines to/from.

If your raditor is low , putting an expansion tank on is a darn good idea. Plum it through the thermostat housing with 1/4" high pressure line. Or (2nd option)off the the vent tube on thr raditor cap. The logic is to compress air instead of blowing off water as the engine heats the collant. This will also help prevent air being trapped in the block, air ain't much of a coolant in a liquid system. Of course the tank must be the high point of your cooling sustem.

WE had a problem like that and found the solution on an off road jeep someone had at a show.the rad was low and had a filler neck in the upper hose at the highest point.WE got the filler neck from moroso and works great usually all the air comes out just in filling system.when we have to run it to get any unrully air out we found out just let it idle dont rev it or you get quite a mess on the floor.Also get the highest pressure cap you can for the rad so water can't blow off there.THinking of adding a petcock to the highside close to filler neck to aid in bleeding air without the mess.
