KIA K900 New Compressor and TXV

[BobbyZ]

I Just finished replacing the compressor, TXV and desiccant bag. Variable displacement compressors are new to me. I just installed and charged a KIA K900 with two 12 oz cans of 134a and the readings I get are about 47 on low and about 147 on high side. This is with ambient of about 72 degrees. The low reading seems high and the high reading seems low?

Are those readings taken/measured at about 2000 rpm ? That is important information.

No they were at idle. I will get right on that. Thanks.

Ok. Started car, I had 45 psi on low side and 150 on high side engine idling at 600 rpm. Ac on high, doors open. Ambient temp 75, humidity 40%.

After car was warmed up, I revved the engine to between 1500-2000 rpm. Low side as 25, high side was 180.

I turned car off. Checked for equalization. Started at 82 on low and 87 on high. Both gauges equalized at 87 psi in about 7 minutes.

Are my pressures in line ?

Sounds decent; wait for temperatures over 75F and see if you and passenger are cool
