When a failed Saab air conditioning compressor is replaced by a new Saab a/c compressor, it is so important to have the lubricant
distributed evenly across the Saab air conditioning compressor and the a/c system before engaging the system for the first
time.

If this is overlooked and the Saab air con compressor is engaged immediately after is has been charged with
refrigerant, it may happen that all the oil in the Saab a/c compressor will be pushed out all at once while there
is no oil yet to enter the Saab air conditioning compressor on the other side. This is caused by the fact that it takes some
time for the oil to spread across the system and mix with the refrigerant. Eventually the Saab ac compressor
may be damaged because of a lack of lubrication during the first few minutes of operation.


This will of course be more problematic after the system has been flushed, this will mainly be the
case after the Saab air con compressor has suffered a catastrophic failure with metal particles from the Saab a/c compressor
being spread across the entire system.


A rule of thumb guide when installing a new Saab air con compressor is to manually turn the Saab a/c compressor pulley
to make sure that the oil is distributed through the Saab air con compressor evenly. Experienced engineers will
normally turn the Saab ac compressor 10—15 times to ensure that oil has been pushed around the system.


There is still more to do to prepare the Saab air con compressor, knowing and following the procedure will be of
great importance if a newly installed Saab air conditioning compressor should fail after a short period of time and within
its warranty period. There is no bigger disappointment than having a warranty claim denied because
something as simple as the following procedure has been overlooked.


Generally new Saab a/c compressors are supplied charged with oil, but it is always recommended that you
check this by draining the new Saab air con compressor to check the amount of oil in the Saab air conditioning compressor.


Then once you have removed the old Saab a/c compressor you should do the same again, empty the old Saab ac compressor
of oil to see how much oil was in it and then fill the new Saab air con compressor with the same amount
this is to avoid over charging the system with oil.


After this has been done and the Saab a/c compressor has been fitted, you do not engage the Saab air con compressor with
the engine running until the following steps have been followed.


1, Open all air louvers at the dash board, 2, Start the engine and let it stabilise at idle speed 3, Set the
blower at maximum speed, 4, Engage the a/c system and operate it continuously for 2 minutes at below
1500 rpm.


After the two minutes the Saab air con compressor oil will have distributed evenly throughout the Saab a/c system.
