Hi All,



It has been miserably cold here for the past month and I haven't flown

my aircraft.  I ventured out to my hanger today (unheated) to be

greeted by the sight of coolant on the floor.  It is dripping from the

radiator area.



I haven't investigated further, I'll have to move my airplane to the

heated workshop area of my hanger first, but I had a few questions for

the folks on the forum.



I have a 50:50 mix of water/glycol in my aircraft.  The coldest it has

been in the last 30 days is zero degrees Fahrenheit, -18 centigrade.

Has anyone had experience of  50:50 mix of water/glycol would freeze

at this temperature ?.  My quick research suggests it freezes at -36F



For people living nearer to the Arctic circle than me, has anyone had

a similar experience ?



Thanks,  Paul

 I think you will find a faulty connection. We get temps down to -25C C with my Europa in the garage. I also use 50/50 coolant.

Hi Karl,



Thanks for sharing your experience. Maybe I will get to move the

airplane tomorrow to  take a look.  Have you had leakage do to cold

fittings ?



Thanks,  Paul

Hi Paul,



My money is on a leaking connector also, hopefully easier to repair than a

split hose 



Best Regards for a new year,

Hi Paul,



The 50-50 mix does not freeze. You have been careful of course and not added water to pre-mixed antifeeze. I had leaks when cold. It seems that the fittings shrink faster then the srew type hose clamps. I aquired spring type clamps to get rid of the problem, but got never time to instasll them. They are yours if you send me your address of forum.

Hi Paul,

  

 I had similar problems with my aircraft - sorted it with Nev's help by  fitting double jubilee clips on radiator connections.

  

 regards
