evo ac problem
evo ac problem
my ac hose the high side(discharge side) was rubbing against the compressor pulley and it got cut through..all refrigerant leaked out so i had no ac for a while...i recently got the hose replaced and charged it with those autozone ac refrigerant charge kits...19oz..it all went in and pressure was reading 32..which is ok but a little low... the ac is cool but not cold enough...so today i got another bottle and try to get it to around 40psi..fill it a bit more... before i even start charging..i hook the gauge up...it was reading 90psi!! with car on or off..it would not charge..i dont get what happened...how it went from 32 to 90psi without doing anything...
when i turn on my ac on idle...it took such a large draw..the rpm dropped down to 300rpm instantly...car almost stalls..vibrates like crazy...no idea why it doing that... can someone help???

Heres proper A/C maintenance procedure:
1.) if you have to remove any component of the A/C you will expose the system to air and consequently moisture. Moisture is very BAD for the A/C and will slowly and corrosively destroy your entire A/C system by mixing to create acids. Make sure after installing a new component, you drain the entire A/C system, install a new drier/accumulator and apply a vacuum to remove all air moisture and contaminated refrigerant.
2.) after vacuuming, you must look up the appropriate weight of refrigerant that you need. don't pay too much attention to what pressure it should be at, because that info is hard to find. Generally the low side will read 30-60 psi when your system is filled. The A/C compressor must be running with the a/c clutch engaged. Getting it to turn on with no refrigerant in the system can be tricky, since the computer tells it NOT to engage the compressor clutch if the pressure is too low. To manually kick on the compressor for charging, just hook it up to the car battery with some alligator clips (ground it to the chassis, and put the positive lead on the positive terminal on the battery). If you overfill, it will destroy your entire system. If you underfill you will destroy your entire system. Make sure you pay careful attention to the weight that you add, the correct amount is under the hood somewhere (I think) or is in the shop manual. Make sure you mix in the right amount of ester oil with the refrigerant as well.
If you don't have the equipment do it right, you better hand your car over to people who know what they are doing (if you want A/C).

p.s.- vent refrigerant to the atmosphere=federal offense
^ Mega fine if you are a tech and do this. Private citizen no worries. It's all hyperbole though. One volcano eruption does more to the environment than all the R12 that could have ever been released.
He is correct, I don't understand how you got it to take the refrigerant if you didn't pull a vacuum on it. A/C systems work off of that.
Global warming is a CROCK OF CRAP.
Sorry for the OT.
