I did a write up on the Mountune install. It's very straightforward. Here it is: https://www.fiestastforum.com/threads/thoughts-from-mountune-radiator-install.23121/#post-408890
I got the Mountune on sale and I have to say that it's one of the best purchases I've made for the FiST.
Temps are always consistent now even when doing some spirited driving, uphill, with AC, etc... I rarely see temps climb over 200'. I am running about 60/40 with a couple bottles of water wetter.
