Thanks for the additional specs. After 26 years and a misplaced orifice tube, who knows if that accumulator is original. I'm guessing it is because the decal is a GM decal. I'll charge to that spec and report back on temps and pressures. I wonder if there was a TSB or other guidance from GM to ...

Interesting that in the *GPD Refrigerant & Oil Guide* that Tim posted in the Automotive Air Conditioning Procedures, Tips and FAQ sub-forum shows the same specs that I posted yesterday, which was 64 ounces net weight (4 pounds) of R-134a, and 11 fluid ounces of PAG-150. Regardless, I would still go ...

In my humble opinion, the single-case design of the 4440 (SD7H15) is superior to the multi-case design of the HT6. Check carefully, but I believe the Sanden should bolt right up.

Sounds good about the OT.

The OEM specifications that I have for your vehicle are as follows: 64 ounces net weight of R ...

Issue #1. No charge at all in the system. Had to go somewhere so I pressurized the system with nitrogen up to 200 psi and went on the hunt. Could not hear anything but then a slight air noise by compressor. foamed it with soapy water spray and it bubbled and foamed from every joint on the HT6 ...

More than just a federal holiday, Veterans Day is a powerful, nationwide commemoration dedicated to expressing profound gratitude to all who have served honorably in the U. S. Armed Forces.

Today is a celebration to honor and thank all of our Veterans for their patriotism, love of country, and ...

According to the A/C specifications that I have, your vehicle calls for the following: 16.8 ounces net weight of R-134a, and 5.1 fluid ounces of PAG-46 oil. The under-hood decal, if it's still there, might differ slightly. If so, the decal always takes precedence.

Compared to older vehicles, as ...

I agree with Cusser .

Some additional thoughts: If your original compressor seized up, it was probably due to a low refrigerant charge, running the system that way, and consequently, oil-starving the compressor. The refrigerant carries the oil, and lack of lubrication equals a seized compressor ...

Kindly start a new topic for your questions.
(Moderator started new topic, above.)

Meanwhile, I have some additional questions:
How did you recharge the system, and with what type of refrigerant?

Add any oil? What kind, and how much?

Did you evacuate the system down to about 29.9 inHg (+/- 500 ...

Yes, the small portable units. There is Vevor (and many similar Chinese brands), the Appion G5Twin and a smaller one by them. I have looked at used RRR machines and some are pretty affordable but I don't know enough to be able to determine if it's operational, etc., and if it would have all the ...

After working on my AC systems and running gauges and all that for several years I am at a point where I'd like to be able to do my own recovery and I wondered if anyone had recommendations for a hobby-plus level machine. I am not in a particular hurry to get an evac done so it seems like one of ...
