93 achieva overheats tooo much/any ideas

my 93 achieva has a new radiator, new radiator cap, serp. belt etc. just changed ac to r-34. (200,000 miles) engine runs good just overheats all the time. I DO live in Arizona but it just does not seen right. Any one with similar problems(/) that they have hopefully solved!

water pump?

I had problem with my 92 olds and it turned out that I needed a
new sensor for the FAN. (or it could be something to do with the fan itself)

I've been waiting a year or so now to fix my 93 scx, after an extreme overheat. It turns out that it was the thermostat that was malfuctioning. You better replace it quick so you dont end up with a ruined motor. It sucked real bad.
