Converting to a radiator expansion tank

I want to convert my 1974 CJ5 radiator with overflow to ground to a proper expansion tank (Not an overflow tank .... i.e. would allow coolant to flow to tank when hot and then return as it cools).

Anyone had any experience with this? I have found several tanks on EBay, but not sure which one I need exactly as it has to be rated for full radiator pressure. I also am assuming that I will neet to change the cap on my radiator. Can anyone suggest a good vendor that could supply all the parts I need??

 

That's a good thread for the OP also. Has lots of good info in it. I use a cheaper overflow bottle with the standard rad cap and it works great. I have it mounted on the passenger side fender down low and across from the alternator (on a V8)

 

I did basically what Patrick did only I used an aluminum water bottle and a bicycle water bottle mount. I had them laying around and it worked great.

 

I went a little more "up scale" with my last version and used a Meziere tank-the rectangular red anodized one in pic, below the air manifold.



Same as this:

Great info....Thanks alot.

 

I used a windshield washer tank from an old Scout I had laying around. It has 3 mounting tabs for easy install and a snowmobile fuel pickup grommet and feed hose works great to get to the bottom of the tank.

 

Nice looking set-up!! What is the "Plumbing" in the forefront of the picture? (solenoid activated valve....etc). Any other pictures of your engine compartment you can share??

 

Mine isn't nearly as cool as that...but here is a pic of it anyway, bottom right corner:
