How much PAG oil is used in Air Conditioning Compressor?


Here is the rule, you pour all the oil out of the old compressor and measure it, then you add that much back plus about 2 ounces. The oil should be virtually clear if it is dark or black flush the AC system with denatured alcohol and compressed air.

1986 Pontiac Fiero. What has to be done to be able to use R-134 refrigerant?


There are simple conversion kits that basically just replace the service ports to use the r-134 type hoses, but it is best to have a pro evacuate system and flush it, draw a vacuum, add correct oil and freon. If the system has been empty or dead a while, best to replace dryer and orifice tube or expansion valve as well.

How much oil is required for a new AC compressor 91 ford ranger, 3.0, the system is completely empty, (replacing compressor, no oil in it)


System 7 to 9 oz

Condenser 1 oz
Dryer or Accumulator 1 0z
Evaporator 3 oz
Compressor 3 to 4 oz

On most vehicles

You have a big problem---no R12 has been avail for the
last 15 years

SO-- you need to flush every component of mineral oil
& replace with ester or pag,then switch to R134A refrigerant

That may require a compressor built for those pressures &
"o" rings such as the green ones

Need to research what your doing

Would the ac coolant need to be replaced in a 1986 model if I wanted to recharge it?


Yes, depending! You would have to get an A/C retrofit kit(basically all it is is a couple "adapters" for the old "refill" HIGH, and LOW ports)
From R-12 to R-134A
(Unless all of this is already done, OR you find someone with R-12 and the right equiptment!)
After you get the retrofit kit, you'll need to COMPLETELY flush the system, get new PAG oil, and refrigerant, get a vacuum on your seems, introduce the PAG oil, reinstate vacuum, and add your refridgerant!


If you could find someone with R12, and the equiptment for R12, it MAY be cheaper. and R12 gives a colder A/C

What is the A/C Compressor Oil Capacity in a 2002 Dodge Durango with the dual system?


The system oil capacity (Total- if all components replaced or flushed) is 10.0 oz. Manufacturer oil proceedure for the compressor alone is to drain and measure oil from the old compressor (make sure to turn shaft a few times to get it all out) and add the same amount of new oil to the new compressor. Chrysler says that you must use a sp15 PAG oil.
Note that you must flush the entire system when replacing the compressor in order for the warranty to be valid on the replacement part. Also require is the replacement of the drier assembly.
Have a great day!

AC system's lubrication amount?


The oil spec is PAG 150--68.00 ounces. General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, now indicates PAG 46 (P46D) oil for those vehicles.
There is a high pressure side and low pressure side to the system. The high vapor=compressor to the condensor. Low side vapor=compressor to evaporator. Your system will use R134a freon.

The A/C is a sealed system and when the compressor fails it circulates debris throughout the A/C system and contaminates it. Before replacing the compressor several other A/C parts have to be checked or changed.
Typically, the condenser should be flushed to remove any debris or contaminated compressor oil. Use approved flushing agents (aresol or liquid pour types), that evaporate quickly and don't leave any residue in the system. You will also need access to 'DRY' compressed air or nitrogen to push the flush through the system. Nitrogen (an inert gas), is best because it doesn't introduce moisture into the system. You need to do this a couple of times.
Accumulator or receiver drier should be replaced when you are replacing your A/C compressor. If don't replace your accumulator or drier you will probably void your compressor warranty. It's virtually mandintory to replace the orifice tube or expansion valve. The openings are usually about .050" and are quickly plugged. Be sure to clean all hose assemblies internally prior to installing your new compressor. Not doing this could contaminate your new compressor. Flush both ways until the flush agent exiting is clean, you will need to remove the hose assemblies to do this.
After you have cleaned, inspected and replaced all the parts, you connect the vacuum pump and remove the air from the system. Make sure it holds pressure. Then recharge the system with the proper freon and oil to the system specified levels.

No matter why you are replacing the A/C compressor there is a lot of other related work that has to be completed before you install the new compressor. Hope this helps, good luck.

Total Amount of AC PAG oil needed for a 2000 Jeep Cherokee sport


Do you have the old compessor? Drain out what is in there and use that amount as a guide + 1 oz. There is no ratio per se. As long as you are close without being crazy low (none) or crazy high (over flowing), you're good.
