car is only overheating when the ac is on, and after driving for about 5-10 miles. any ideas why it would only be overheating when ac is on or things i can do to fix this.

 

Do both fans come on with the AC on?

 

yes i was having trouble getting the radiator fan to come on and now both fans are working, but car is still overheating with ac on

 

ive already gotten both fans working properly and changed t-stat, any other things that might be causing this? and it doesnt seem to be losing coolant.

 

your radiator and/or a/c condensor fins may be clogged or damaged.(clean/straighten)
your radiator maybe a little clogged internally, (back flush??)
your fan may still be having some problem
your water pump needs to be changed.
going down the dark path after that.
how old are those parts, how many miles on car, was car always maintained regularly?

 

Check components. I had the same problem in Arizona last month, driving on the freeway. AC on; car got hot, did not "overheat". If I shut off the AC, temp went down. I got back to CA at 106 degrees, it was fine. I asked other people in AZ if they had this problem, they told me; the older cars. It was blistering hot there. My system is clean and GTG. Car has 160K, I figured it was just too hot! There are some additives (water wetter), that help dissipate heat, let a little coolant out and put in a bottle. I have used it in other cars, it worked for me.
