My initial thought when starting the experiment was that there had to be a by-pass hole in the new 'stat to prevent an air lock and to enable the hot water to reach the unit to cause it to open. I tried various sizes of holes but then discovered that there is a well hidden small hole in the Chevvy one.
No further holes have proved necessary. I have had no problems with my installation which was allowing a maximum of 74C with the old stat and now runs between 87C and 93C depending on engine load. The warm up time is not radically improved since the diesel struggles to reach temperature in the cold weather anyway but I now have warm feet which I certainly didn't have before.
