Quite some time ago (maybe 10 yrs?) Ron Gowan lost all the coolant in his Long-EZ and flew for a really long time (20 min or more?) before landing and taxiing up to FBO.  Trashed engine, but ran all the way to shut down
Details are really hazy, but time was VERY impressive ... Jim S.

Greetings,  We've established what happens if the engine runs out of oil.   What about coolant?  If the system sprang a leak, and you continued to run at cruise power,  will it eventually seize, similar to the oil out?  I can't say I've heard of that happening, but most people probably quit before they get to that point.  I'm thinking it would seize though.   The reason I'm wondering has to do with thoughts of a backup water pump.  I'll almost certainly use only the DC EWP on the single  rotor, but I'm wondering if a second one is needed.  I could live with the loss of the engine due to warping, if it didn't cause it to seize in short order.  Cheers,
