Nissan Xterra overheating

Kind of a long post sorry in advance. I have a 2010 Nissan Xterra 2wheel drive that has 130k onit. 8-9 months ago a hose between the radiator&tranny busted mixing fluids causing me to have to replace the radiator and transmission.
Fast forward a couple of months and the connector that connects a hose with the hearer core busted and thats when my problems began. . i managed to slowly get it the 3 miles home stopping before it would over heat. So i had a mechanic replace the connector, flush radiator,went ahead and put a new thermostat in and new radiator cap. On the city streets its great but when i drive over 55mph for more than a couple of miles it gos from just below halfway on the heat gauge to almost topping out just barely below the H. When it gets up there the air starts blowing warmer not hot but not cold either. The ac runs really cold every other time. So took it to a diffrent mechanic he replaced the fan clutch and did some kind of gas check to see if i possibly had a cracked head or something leaking gasses into the water but it passed that and my oil looks good but its still getting hot. I also should mention that a couple of weeks prior to the hose connector busting my wife had a very minor accident that barely dented the front bumper, i dont think that has anything to do with it but just wanted to mention it. Im to the point im sick of waisting money and not getting it fixed. Any ideas what could be the issue?

Why would someone replace a fan clutch for poor heater performance? Could be air trapped in the coolant system. Hopefully it isn't combustion gasses getting in there. How is the coolant level in the radiator when the engine is cold? Did they vacuum fill the system or use a funnel to purge all the air out?

Not sure how they filled it up. The weird thing is i can drive all day on city streets and be ok but as soon as i get on the interstate and go any speed for more than a couple of miles it gets hot.

Combustion gases getting into the cooling system from increased RPM.
