Overheating over 60 mph

You've got a clearly identified deficiency. Your undertray is missing. Don't waste time/money on anything else until that's remedied.

Thanks guys for all your help... I will definitely get the undertray...

First thing, replace the undertray.

Second step, replace the thermostat. They are cheap, readily available, easy to replace, and known to fail.

Thirs, if that doesn't solve the problem, pressure test the system.

Glad you're listening and on the correct path. All's well that ends well as long as those dancing bananas stay off my lawn.
