Re: Various Scales on Manifold Gauges

I'm not an AC expert, but have vehicles with R134a and one still with R-12. I only use the psi scale.

Re: Hunting down AC Relay for 1989 Mazda truck

The relays I have all have number 334160 4386 and 12V stamped on them, but no
manufacturer name, and I couldn't Google any matches.

Hunting down AC Relay for 1989 Mazda truck

Someone I know bought used AC parts to add AC to his 1989 Mazda B2200 truck, and got hoses re-done and a brand-new compressor. But he's missing the AC relay on the evap box (and it's small harness). Can someone supply a factory part number for the factory/dealer AC relay, or is there a universal typ...

Re: Turning on AC or Heater caused idle to drop severely

Vibration could be due to a loose compressor mount too. Yes, from your story yours needs to have the leak fixed (don't use ANY sealer), a new drier, then have the system evacuated, and the correct amount of refrigerant added. Yes, special equipment is needed. Otherwise you're just doing a band-aid. ...

But I feel afraid of adding more r134 to achieve the values of the chart and damage something. Wellcraft ...

How much torque needed to turn a compressor?

How much torque needed to turn a typical good compressor? On a truck board/site someone reported their compressor required 250 inch-lbs (which is like 16 ft-lbs) to turn, and an off-the-vehicle compressor only required under 20 inch-pounds. I had my 2004 Frontier with 90K and great AC (R134a) handy,...

Re: Corvette A/C rebuild

the hose that goes to the condenser is the high side The hose that comes from the evaporator and accumulator is the low pressure side. Add the refrigeration oil, then turn the compressor (not just the compressor pulley) through at least 10 revolutions with a wrench before evacuating and adding refr...

Re: Ac troubleshooting

Get a real gauge kit so you can really check both low and high sides.

I hope - for your sake - that your "kit" didn't have any SEALER in it !

Re: 71 Chevrolet C/10-Pressures good / air only cool?

Condenser doesn't look so clean to me either. Also make sure the fan clutch is good.
