i have a 97 3.0 CL and had the AC compressor replaced with a new one and all the other new parts (xpansion valve,,dryer and $40 of Freon ) but the air conditioner is still not cold...cool (it is 106 outside)...but even at freeway speed..not ever cold..even in the morning.( 90 degrees==Palm Springs).does anyone know the specs on output temp for the AC? A pro did the job and coincidently??? when i got it back...it now overheats..didn`t overheat before the repair......can anyone help me with some advise or suggestions on this...thanks...es335

 

Replace your thremostat man, I guarantee you that's the problem

 

The shop that did this work should resolve the problem.

I would check that the cooling fans are both running when AC is ON. This will cause overheating in some cases.

There is no specific "output temperature", however in general you should see at least 35F pulldown for air entering the evaporator (floor temp) to air vent temps. So 80F input and 45F output are reasonable performance.

For further insight, you will need to supply system pressures (hi and lo side), taken at 1500 rpm, max fan, recirculate, and car in shade.

good luck

 

Did you get your high and low pressure hoses to see if theres any leaks?

The shop should have put A/C dye in there to see if theres any leaks.

Also check the needles from the pressure hoses (where they charge the a/c) make sure they are screwed in tight enough and there isn't any freon leaking from them.

 

Did they check the condensor for leaks too?

 

Both fans are running..but the heat gauge would still hit 80% from the Red,,,Thermostat sounds like the culprit. I am taking the car back to the shop in about 6 hours and have printed your suggestions so i can ask the right questions...again thanks for your help...you rock!!

 

i will sell this green 3.0VL when i get it running right.it has needed work from time to time...but i always had it done..i still love the car.but with 5 grandkids to haul places , i just need more room.i need more room...shot me an email if you are interested and i can send some pics....or i may post them here if that is ok with the boss...if you need it delivered, i can work a deal to get it to you as i am retired and between gigs.
