Getting Hot on the Freeway

I thought it was but I look back in my records, and they only clean it and put new tanks on it last year. And I did see the inside of the core and it's ready. That core was a 4 row Desert Cooler that was from 97 that my records show. So I'm putting a 5 row and little bit thicker radiator in it now. So no I'm not getting ripped off or anything!!! This has to be the problem, because I always thought I had a coolant flow issue and that shroud can't block that much air.

I wanted to thank you all for the info on this post I was having the same issues using a late model shroud with my flex fan (I know evil). every time I get over 65 the temp gauge would almost peg slow down below 65 and it would drop to the middle. it all started after I did a tire change and added that shroud. pulled the shroud off this morning did a 140 mile road trip 70+ the whole way and never even got to the middle and it's over 90 today. Thanks again! I would have never thought the shroud would be causing it I was actually trying to find taller gears so I could lower my highway rpm's hoping that would fix it!
