Re: 2013 ford Taurus curious question

As Tim alluded to in his questions, a couple of problems you might now have is the amount of refrigerant and oil in the system. This vehicle takes 26.0 ounces (weight) of R-134a and 7.0 ounces (fluid) of PAG-46, and they need to be exact. You didn't say whether you evacuated the system, how you char...

Re: RV A/C trouble

Thanks for the help. The fan was the problem. My gauges now read 35 low and 225 high and I have cold air. Pressures look good assuming an ambient of ~90 degrees. With virtually no air flowing through the condenser during your earlier testing, it's no wonder you weren't getting any cooling. Glad you...

Re: Low Pressure Switch

Have you also checked the clutch gap with a feeler gauge? If it's wider than 0.020", the clutch might not engage, especially an older unit when it heats up.

Re: Low Pressure Switch

I'm curious as to why you think the LP switch is bad. Are there any other components that you suspect might be leaking and/or defective as well? If so, and if the system hasn't been serviced in years, I'd go ahead and recover the charge, or have it done, then repair and replace whatever is necessary.

Re: Conservative A/C Restore?

If you want to convert it, you'll need to remove the VIR unit because it won't work well with R-134a and replace it with a clutch-cycling accumulator kit. However, I think I'd keep it R-12 for which it was originally designed, rebuild the VIR (parts are available), replace the 44-year-old compressor...

Re: RV A/C trouble

A nonworking fan will certainly raise the pressures, especially with the unique system design of your RV. At least you won't have to recover and recharge the refrigerant again to replace it. At 85 degrees ambient and the fan running at full speed, the high side should be somewhere in the low 200-PSI...

Re: Compressor Cycling

I agree with the previous assessment. Furthermore, I think that these kits should be banned and permanently removed from the market. Mobile A/C systems are technologically complex, very tricky to service, and not DIY friendly. Contrary to the marketing publicity, a system won't be fixed quickly and ...

Re: RV A/C trouble

What is the make, model, and year of the vehicle? A few other thoughts and questions: I assume that this is an R-134a system and that the under-hood decal specifies 2.8 pounds (44.8 ounces) of refrigerant. You mentioned that you evacuated and charged it with only 38 ounces...6.8 ounces shy of the sp...

Re: Compressor relief valve diagnosis

If it has the original Denso compressor, the thread size is M10-1.5

Check with Tim at ACKits.com for the correct OEM part.
