Yea,, but remember, it's got no antifreeze in it, just straight water under pressure at 240+ Even with antifreeze, when they overheat severely, the coolant makes all kind of noise after shutdown. I still think its headgaskets too, but I'm STILL, not convinced. I only ever checked the purge line flow, when it was cold. I think, I'll ck it after it's got hot, n see if it's still flowing.
