But I still don't buy it. You could easily get 1 pint through a 2mm opening in less than a minute using just gravity, let alone high pressure. Back in college I could calculate the pressure required. But I'm much dumber now. Dave Leonard ------=____1082911374361_?8xYtKFfwa Content-Type: text/html; name="reply" Content-Disposition: inline; filename="reply" Re: [FlyRotary] Re: FW: Sad story

 It's possible I misunderstood the explanation but the theory of why this happened seems unlikely.  The sudden expansion of coolant would have to be incredibly fast to cause an overpressure due to not being able to get out through the overflow tube fast enough.

I just learned it was a ¼” line; i.d about 1/8”.  Trying to squirt a pint or more through that in; what; less than a minute? That could do it.  I currently have a ¼” line on mine as an overflow from the pressure bottle.  The pressure would release from the cap (through the upper gasket) but I would lose coolant in a similar scenario.  I’m going to rework that to a 3/8”.  That will give 4 times the flow area.
