[QUOTE="JEEPSTER401, post: 1548809, member: 3946"] It would puke at idle and all the time that I have had it if I let it get that far. I didn’t put a new cap on but I did monitor pressure on my tester. After 12 minutes of idling it was at 14 PSI of coolant pressure. Coolant was rather cool yet, I’m in Michigan. I was going to get new additive for my combustion leak tester but in the past when it gets old it changes color in the bottle. It is still bright blue. If I run it with the cap off it will eventually just overflow, turn it off for a while, it will gurgle down to where it was prior to starting. And of course no heat, ever. There is a ton of air coming from somewhere. [/QUOTE]
