Re: Using Shop Air To Leak Test?

Desiccant won't give up its trapped moisture to vacuum during evacuation. Use nitrogen or a can of R134a for leak detection by bubbles, electronic sniffer, or UV dye. Hi, I see guys on U-Tube, using shop air and a soap bottle to find leaks in Auto AC Units. Yeah, and I see guys on YouTube riding bic...

To me, this is the biggest clue.

And note that sight glass is really not too useful on 134 systems.

Re: Options to fix this compressor, 2001 Honda Insight?

I think I'd also lean towards brand-new compressor. But since you have used parts available, and the compressor shaft turns and you say it appears to contain your R134a, you're not out much to try your used parts.

Re: AC working, but vent air still not cold

Fluid pressure is about 30 psi on low side when compressor is engaged. Any input or ideas would be greatly appreciated. Need high side pressure when running at about 1800 rpm. If you don't have such service gauges, then silly to try to diagnose yourself. When I put the temperature selection to a hi...

Re: Why hasn't R1234YF dropped in price much in the last few years?

Honeywell has a monopoly Automotive refrigerants that leak out of A/C systems contribute very little to the overall global warming problem, only about 0.14% according to scientific estimates. Even so, when you multiply the millions of vehicles that are AC-equipped times even a small amount of refrig...

Re: A/C blowing hot air

1. There are aerosol cans of AC flush available at parts stores, then use your compressor to blow off any remaining solvents. I think one of the sponsors of this site sells kits fro professional mechanics. 2. I don't know specifically about your vehicle, but bad actuators could cause air to get defl...

Re: 06 Jag schrader valve replacement

To me, it's just so weird that low-volume vehicle manufacturer Jaguar would use such a specialty schraeder valve in the first place !!!

Re: 2015 BMW X5 7SBU17C compressor clutch gap

Go to a higher-end bike shop. Ask to see some brake shims. ACE Hardware also. .... there are several ACE Hardwares. What exactly would I be looking for there? Brake shims as well? Just look through all the little drawers, stuff sometimes has "interesting" names. Did you actually test your...
