Second I installed a small bleeder plug on the top where the cores are fed. It turns out that neither are required. When I fill the system though the rad cap, I fill until full to the cap, then start the EWP. It usually requires a couple of squeezes on the hose to burp some air out of the pump, then I can continue to add coolant until full. Once full it will continue to bleed air out and you will have to continue adding a little each minute for about 15 minutes. After doing this I checked the small bleeder plug and found that there was absolutely no air whatsoever at the top of the cores. After running the engine up to temp for awhile there is more entrained air that gases off, but that is mostly forced out into the overflow tank which sucks back coolant after cool down. I've found that I usually have to add approx. 1/2 litre to the overflow tank after cooldown. Ed, for the record you can add me to the list of parallel cores. S.
