opps, sorry KC, been out off pocket for 10+ days and only checking periodically. My first guess would be that the juice in the systme is no loger available not because it is dangerous but replaced with something else that is better - maybe more stable, less aggresive on seals, bla bla bla...

I would think that there are fluids (heat transfer oils) that would work. If he needs a small amount you can always use a seldom used trick and contact a mfg of the stuff, tell them you require a sample for test purposes - that is if they don't sell in small amounts.

Allow me to investigate - there is always different ways to skin a sheep...
