When the ac kicks off see if the ac condensor fan is on and blowing out alot of air.Also check the radiator and condensor for debris in the fins like sand etc.

So sorry some how i didnt get a email alert saying you posted a response.Possibly your friends car gauge isnt reading correctly or she has a bad radiator cap not holding pressure.Does her radiator fan work?

The ac condensor is on the other side of your radiator facing the front of the car.

my condenser didnt have debris in it also so what could be all the prime reasons why my car temperature would get higher after running my ac for a while.

The prime reason running the ac for a while would engine temp is because its putting a load on the engine running the ac compressor.So does the ac condensor fan come on with the ac running?As far as the power steering as long as pump is bolted up square the pulley is on correctly?The belt is on right and the pump isnt noisey then the pump is on correctly and the air is bleed out of it.

ok the only thing i left out was my engine temp problem probly came from driving with no power steering fluid cuz at the time when i texd you guys i was driving without power steering at that time i read a article of a guy dat had da same car i had and somehow a power steering line is hooked up to my fan and after i changed the power steering pump and got rid of the leak the overheating problem went away.

i changed the sending unit and the fuel gauge started to read better. now the thing about my cluster gauge is the lights that are suppose to work on the arms are off but the temperature,idle, and speedometer gauge work fine still the light on the arms dnt shine, im thinkin if i get a cluster gauge the fuel gauge will work properly alot more and i could get the lights on my arms bk on. i dnt think my ecm is bad i was just wondering cause a guy with a 99 model said he had to do that

Isnt there back light bulbs to light up the needles on the back side of the cluster?I would check that before thinking about changing the cluster.
