What type and amount of compressor oil is required for 2000 silverado 4.8L a/c

The amount of oil is 8 Oz, Type is pag 150 but GM superceded that to show pag 46

You will have to take it to a shop and have them hook up a ac machine and perform a evacuation on it. If your the by yourself you will damage the compressor

NEW AC COMPRESSOR POUR OUT SHIPPING OIL COME WITH IT ADD THEM SAME AMOUNT.IF YOU NOT SURE AND OIL BEEN POURED OUT.ADD 2 OUNCE R 134A REFRIGERANT OIL TO NEW COMPRESSOR. YOUR AC SYSTEM HOLD 1.75 LBS R 134A REFRIGERANT.

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!

This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!

You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.

You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.

Take this job to a qualified shop.

Sorry

You need to also repalce the drier, make sure the compressor has the amount of oil required, vac down the system then charge with proper amount of r134a.

Look way down on the engine front area passenger side for the compressor.
Is the belt gone?
Check the belt tensioner pulley....can you turn it?....is it seized?
If it is OK then try and turn the compressor.......and the idler part of the compressor.
If the compressor is seized.....why?
Usually lack of oil in the system,or an overcharged system.

Once you have removed the 134a gas from the A/C system before removing the compressor and before installing the new compressor make sure you add the correct amount and type of oil into the system to prevent another seized compressor after you have flushed the system to remove contaminates such as old compressor grindings......if the compressor was seized.
You will also need a new receiver/dryer once you open the system to the moisture in the air.
Do not expose the new receiver/dryer to air....install last.
Vacuum the system well before refilling with the correct amount of 134a.
At 70 to 80 degrees outside temp........a vent temp at medium fan speed of 48 to 45 degrees should be a full charge .......use this reading if you do not have a electronic scale and/or A/C machine.
DO NOT OVERFILL THE SYSTEM.

Sometimes there are plugs in the compressor when shipped. Make sure that there is nothing in the compressor where the line attach. How much oil did you put in the system. Compressor are shipped with oil in them. The correct way to measure would be to drain the oil compressor and measure that amount. Then drain the new compressor and compare the amounts. Put NEW oil in the new compressor. Remember the compressor can not compress liquids. It is possible that there is too much oil in the compressor.

THERE IS NO SET AMOUNT, U DRAIN THE OIL OUT OF THE OLD COMPRESSOR AND THEN ADD THAT SAME AMOUNT TO THE NEW ONE PLUS ONE OUNCE

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.
