Here is how I keep mine cool.This is the after market gauge in my bird,it reads exactly the same as the one in the cluster.That temp was taken about two years ago at roughly 60 mph and 78* outside temp.I have never seen a temp above 195* under "any" conditions.The radiator is the original 956 with a four core,180* stat,fixed seven blade fan and shroud and 6 blade a/c pump and all nose cone seals intact.If everything is as it should be including all nose seals intact,you don't need water wetter or anything else.If you have any doubts,come see me and I'll hand you the keys!
