? about coolent recovery

Yup, my Moroso catch can has a little hole in the top of it. Can't tell you my drill sizes too well, probably the diameter of a hanger. lol :D

Also if you guys plumb the line from the radiator to the BOTTOM of the catch can, it will recover and recirculate any coolant your system pukes. Instead of just pouring it into a can you have to empty. Seen a few just stuck up top. :)
