Re: Fan does not bring down high head pressure
Both of the pressures are too high. I'm surprised you get any cooling with a low side of 40-45 PSI. A reading of ~45 PSI means an evaporator temperature of ~50°F and center vent temperatures even higher than that--hardly adequate for comfort on a hot day. Try misting the condenser with a garden hose...

Re: Gs300 new ac components but immediately shuts off
That 'Code 23-Pressure Switch Circuit' is also suspect. Are you still seeing that, or has it gone away? The RPM sensor on the compressor rarely if ever goes bad. I don't think the ECM will let you bypass or disconnect it without introducing some other problem. I recall that you mentioned changing th...

Re: Metric to SAE/standard A/C plumbing questions
I worked in an industrial chemistry laboratory for over 4 decades. SwageLok fittings are absolutely the best, and the by-far most-common fittings used in gas (and liquid) chromatography. What that means for us here is that these fittings were leak free for hydrogen (explosive) and for helium molecu...

Re: Metric to SAE/standard A/C plumbing questions
The Swagelok straight union fittings available to go from a 8mm OD to a 3/8" (-6) OD tube can be had in 316 stainless steel, or brass versions. I'm pretty sure both are harder metals than the aluminum tubing, so either should work mechanically according to Swagelok's website. Which would be a ...

Re: Metric to SAE/standard A/C plumbing questions
Seems like the best solution is to use the Swagelok transition fitting to connect the larger and smaller tubes instead of TIG welding or brazing them. Although any time you combine (stainless steel?) ferrule-type fittings with aluminum tubing (electrolysis factor due to dis-similar metals), you'll h...

Re: Metric to SAE/standard A/C plumbing questions
I'm not familiar with the acronym "MIO." What does it mean, "Metric Input Output?"

Re: Should I try control valve or just replace compressor
ok, I'll replace all of those parts and the suction/discharge line as it does have mufflers. Sounds good. I'll flush the evaporator and its lines. I definitely want to do it right and not have to go back into it later so I don't mind spending a little more for a better chance at success. Nothing wo...

Re: Can I drive with my system before filling it up
I did some digging around when you mentioned the cut-off switch. I’ve found it does apparently have one but I’m struggling to figure it out. I read somewhere else that it’s likely to be on the drier (accumulator?) and after I pulled a cap off I found two electrical spade type connectors, which I’m ...

Re: Should I try control valve or just replace compressor
Finally got back to this car. Recovered and recharged to oem level. No help, still poor cooling. Pulled orifice and it looks like this. Not a good sign, this is going to be entire system as John described? Based on the look of the OT, I'm not surprised that the cooling performance is poor. Little t...
