If the temps were in the green like everyone (1 poster) is saying, then the problems that I heard resulted would be extremely rare and for it to happen on a similar aircraft within a week, whilst operating in normal temperatures would be an absolute rarity. That being said the failure on the day doesn't necessarily as a result of high temperatures on that particular day; the damage could have already been done. Even if it did get overheated, there's no guarantee that it would cease at that time.
I suspect at some stage, possibly in the very high recent temperatures that the aircraft has been operated beyond its' documented operating limitations (mind you, one such limitation is 39 degrees).
Keeping a good eye on temperatures is always a good idea and it's unlikely that it will be documented in the POH that the aircraft will overheat in certain conditions. It's not just limited to Jab's either; I have had the odd Cirrus SR20 overheating on me on certain days.
