Refrigerant Type: R134a
Country of Origin: United States
I will flush my a/c system today. I will install a new compressor, accumulator, orifice tube and condenser. I assume after the flush all of the oil has been cleaned out. When I hook everything back up, the new Motorcraft compressor came filled with 7 ounces of oil. The specs on my climate control system shows 6.6 ounces. Sorry to ask what might be an obvious question. I ordered the Motorcraft part specific to my car and it came with 7 ounces. Is that too much for my system - would I need to remove enough to get to 6.6 ounces?
Thanks in advance.
This is not too much lubricant for the vehicle...however, how do you KNOW there is 7 oz of lube in the compressor? I would not trust a label on a compressor for this very important aspect of the repair. Suggest to drain the compressor....discard all the lubricant from the compressor. Obtain a quality lubricant and add back the correct amount of lube....3 oz in compressor suction side....the remainder can be added to the inlet side of the accumulator. A bottle of lube will contain 8 oz...go for it all. This extra will not harm the system.
The key is not only the amount of lubricant in the system...but most important the total amount of refrigerant in the recharge.....this should be done with the proper equipment...not several cans and a gauge set.....get it done correctly...or you will loose the new compressor...new accumulator...heck..all of it. The refrigerant is what will keep all parts lubricated.
Oh, yes....when the compressor is filled with lube...stand the compressor up on its drive plate (front of compressor) and allow it to rest in this position for 10-15 minutes. This is a good method to prelube the shaft seal.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
