2000 Explorer 4-Door 2WD 4.0L SOHC 140,000 miles. R-134a refrigerant, PAG 46 oil. Do these A/C pressures look OK... or do they indicate that something's wrong?

All doors and windows open, parked in the shade, A/C on max (recirculate) and maximum cold, front and rear blowers on high.

85 degrees F ambient - steady 1500 RPM for about 10 minutes - 32 low side - 225 high side.

86 degrees F ambient - at idle (approximately 600 RPM) for about 5 minutes - 45 low side - 215 high side.

87 degrees F ambient - at idle (approximately 600 RPM) for about 8 minutes - 47 low side - 235 high side.

Your thoughts? Thanks.
 






SOLVED. NEW MEASUREMENTS. THESE MEASUREMENTS WERE GATHERED USING THE PROCEDURE OUTLINED IN THE FORD DOCUMENT.

89F - Ambient temp in front of condenser.
41F - Middle vent temp. Ford chart states a range of 38-49.
23/205 PSI - Low/high at 10 minutes. Ford chart states ranges of 21-52 and 182-275.

I have the Ford document that outlines the procedure and contains the charge chart, vent temp chart, and compressor cycling chart. It also includes an excellent, extensive table for diagnosing A/C problems. If you'd like to have the document, send me a message and I'll get it to you.
