Coolant flush... then the hose blew off (Page 2/2) theogre APR 30, 08:39 PM (Power Out today while trying to post so this is slow...) It's P-side pipe? yes so most coolant is gone but... Test the "water" in the system. If test reads <50% coolant add more pure product to fill. Or drain the rest and refill. If test reads 50% - 70% add 50/50 Premix. pHoOl MAY 01, 07:16 PM I got it hooked back up, filled, and tested. Holding fine now... I must have just put the clamp in the wrong place the first time. Thanks all for the help!
