Yes, Because it won't work right if you do not oil.
No it can't. The compressor breaks internally and that is why it locks up
Recently, my air compressor broke down and I'm wondering if there's parts to repair them or do I need to buy a new one?
You should not put any oil in a Ford air conditioning compressor. The air conditioning compressor runs on Freon. The system should take about one pound of Freon.
You are better off replacing the whole compressor. You can purchase a remanufactured compressor for $30 more and it comes with a 1 year warranty. Also replace the dryer/accumulator with this. It only has 4 bolts that hold the compressor on and it's a one for one swap. First, remove the hoses from the dryer SLOWLY!!! This will allow the system to depressurize. Once the air stops hissing, remove the front and rear connectors from the dryer. Remove the 4 main bolts from the compressor and the one bolt holding the hose connections. Remove the serpentine belt and lift off the compressor. CAUTION****** Drain the oil from the compressor and fill the new one with the same amount of new GM AC oil. Install the new dryer and the new compressor. After installation, I suggest taking the vehicle to a service shop and have them vacuum the system and recharge it. You just saved yourself approximately $400 anyway, so having a professional perform these tasks is only a few dollars. This could save your new ac system in the long run.
One of my air compressor broke and where can I find a great place to buy a new air compressor?
Empty, 8 oz. If you're replacing one major part such as a compressor, condenser, evaporator or accumulator, add 3 oz.
if your uing air tools on the compressor then you will put one or two drops directly into the inlet where you connect the compressor hose
You would need to add pag oil to system if you lost some such as when replacing the compressor, condensor, receiver dryer, evaporator or a blown hose. Replacing any one of those items you would add 1 to 2 oz of oil into each item during assembly. You didn't mention what vehicle you have but most systems use aprox 8 to 10 oz of oil for the entire system if it was brand new and bone dry. If you want to add oil because you want to, you can purchase a can of refrigerent with oil and suck it in thru the low side with pump running.
The oil is there for one purpose ,thats to lubricate the compressor ,but it also traveles with the refrigerant through the system and when you have a leak it will be forced out the place where you have the leak ,thus after awhile you will lose some oil ,generaly the leak will be around the seal in the compressor.
I'm in the process studying for my epa test and this is one of the questions and their answer is foaming occurs in the compressor.
Oil starvation is one possibility. The refrigerant is what transports the compressor oil through the system - an insufficient amount of refrigerant won't properly transport the oil, and it'll starve the compressor of lubricating oil. And insufficient amount of compressor oil in the first place could also be a cause, especially if you're charging a dry system. If you did add oil, did you spill any on the compressor? Because I've seen that cause what you're describing, as well.
I am retrfitting ac on 93grand am and the refridgerant cans to recharge it say "includes oil". I have to have the ac system evacuated and was told this would pull most of the oil from compressor out. One guy said the oil weren't compatible so I should remove compressor and dump the oil out the back of it. Hope this helped
