[QUOTE="SecondhandSnake, post: 16419882, member: 116684"] Yeah there's no real need for the fox/SN radiator with a fill cap. If you wanted to run one for some reason, you'd want to run it with a higher pressure cap than your expansion tank, more or less so it doesn't actuate. I'm doing that with my Subi radiator that I had to run for the center inlet out of necessity. But basically just think of it as running a stock style system, just with a thermostat relocation and expansion tank relocation. Fill it the same way you would the stock one. Open up your crossover and expansion cap. Hook up your pressure fill system to the draincock/compucheck fitting. Push coolant into the system until it reaches what becomes your new "fill cold" line on the new expansion tank. You should try to leave approximately 10-20% of the system's total volume empty in it. (Ex: 10qt system. Stop filling when there's 1-2qts of the expansion tank unfilled.) Now cap off the expansion tank. Continue filling until you see it up to the fill plug. Close the fill plug. Now for the deaeration (burping) process. I've tried doing it the Ford recommended way with the funnel in the crossover. But it tends to make more of a mess than it's worth, and provided you didn't do anything too crazy to goof it up, you can just heat cycle it a time or two and then top it off from the crossover plug. I barely need to top mine off, and that's with a top fill, not a pressure fill. [/QUOTE]
