5 teaspoons will do it,just put 3 in the condenser and 2 in the receiver/dryer.Put the receiver dryer on last as it absorbs moisture like crazy as that is part of it's job in the a/c system.MAKE SURE you vacuum the system VERY well before adding factory approved 134A refrigerant.DO NOT add any refrigerant with an EXPLOSIVE sticker on it.These after market refrigerants are usually a mix of butane and/or propane and you may not want these products in your a/c system in an accident situation where your a/c system is ruptured and the flammable gas enters your passenger compartment.Fire is never a good thing in an accident.

The correct way to do this is to drain the compressor and add the amount to the system shown on the label under the hood give or take a bit the oil is hydroscopic and retains water and all needs to be out of the system and then evacuated to get all moisture out what remains and then and only be recharged water in a ac system makes ice not what is wanted you should use a registered ac engineer to help

Testimonial: "I've read it online that 1oz in the AC condenser and 1oz in the AC receiver drier should be good enough. The system will be evacuated and recharged anyway."

AC compressor noise


it will not eliminate the noise. you'll need to replace the bearings.besides from the knocking noise is the air coming out from the vents cold? when you recharge the freon is it totally empty? if thats the case you probably have a leak in the system . check all the lines and connections for leaks using liquid soap add a little bit of water to make it bubbly.start the ac and use a sponge.normally when there is a leak the oil will leak together with the gas so ypu'll need to add some refrigerant oil as well pag oil is best..but i'll need more details so i can help you out

How much pag oil a/c was vacumed


Probably none, or very little. Most of the oil stays in the compressor and the condenser, so the normal procedure is to add an ounce or two unless you are replacing a major component.

How much oild to put in the ac compreeser


unless you are changing a new compressor you should not have to add any oil in there. Do not put oil since the compressor already has enough oil in it. If you put oil in there and it already has oil, the AC system will not function properly because it has too much oil. How much oil to put in there is determined how much is already in there.

A/c clutch seized


Sounds like you may have debris in your a/c system. From what you describe your going to need another compressor but before you hook the lines to it do a couple of things. Remove the reciever drier. remove the expansion valve. With the all the componants removed flush the lines and system. Flush kits are available at most parts stores. Install new expansion valve , new reciever drier, hook up new compressor. (make sure you add pag oil to the system, Check how much the system holds and add accordingly) Evacuate and recharge and you should be good!

How to replace an ac pump?

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.
