Is it cost effective replacing coil and clutch after they melt? Or total rebuild?

Do know that when system is ready to engage compressor no matter how that's accomplished it needs oil quickly only carried along at about the time it can blow cool air. IDK - bet a lot of quick failures are running a new compressor dry of oil taking too long to have charge proper or real close. High buck equipment can do that before you even allow a compressor to engage. Most folks wouldn't have that caliber of equipment.


As said, risks are high for things to get costly. Mistakes are #1 on the list,

I don't have High buck equipment , and I'm not trying to insult anyone by questioning why another 2 oz through vacuum during charging has a advantage over adding 3 to the evap before evac, as its first in line before the compressor. And Im assuming you meant another 2 oz through vacuum during charging, on the .low side

The last, and first time I added per weight, I got 70% in before starting the compressor.

Thanks

As I said before, don't add oil to the evaporator. It will just hinder the cooling.

If you don't want to suck it in during vacuum, just pour the 2 oz into the accumulator, assuming it has one.

Thanks, yes there is a accumulator.

Unfortunately, FedX damaged my new condensor and the accumulator caps were removed when I received it.. The bypass pulley was a mirror image of what I need.. So still waiting.

I noticed the new Denso compressor I have says it has all 7 oz of oil in it.

What should I do? Dump it out and start over with my supercool pag 46 oil spread out in the system?

No, I would just leave it in there but remember to spin it a few times to purge it once everything is hooked up so it doesn't crash when it engages.

One last question maybe.

After pulling good vacuum, did triple, should I pull 44 oz of 134a in the lowside as a liquid from my 30# jug?

Last time, I think I added some gas and then switched to liquid and got 75% of the charge in before starting the engine.

Whats the correct procedure?

Thanks

You can charge liquid until you start the system, then you have to charge gas. Make sure you use a scale.
