Cooling System solved (again)

 I hesitate to say that my cooling system problem has been solved, but I am cautiously optimistic this time.   I felt I had proved that all the problems were caused by a leak somewhere in the system, and I had eventually traced it to the seal between the expansion bottle and the pressure cap.   Although I had tried 3 different caps I decided to try once more.  I also upped the pressure from 20psi to 22psi.

I did about 110 miles yesterday and the temperature gauge hardly moved from about 90℃.  And this morning I checked the water level and it hadn't changed, so maybe it was 4th time lucky ?

We'll see.
