Not easy finding a radiator shop these days as with all the competition of aftermarket items and the EPA guidelines most shops closed their doors .
The reason the fans come on at freeway speeds is I have set the fans 'ON' temp to 190°. So anytime, regardless of speed, when the temp exceeds 190° the fans come on. Even with the fans on the temp would increase.

I don't have any temp creep with the medal fan installed.
