I'm going to start my own thread instead of tagging on to Joe Blow's, but I hope someone can gain some knowledge and help me out at the same time.
I'm replacing my compressor with a Denso (at least made in Korea and not China) that's supposed to come prefilled with oil. The instructions provided with the compressor say to empty and measure the oil in the old compressor and new compressor and adjust the oil in the new compressor to the level of the old compressor. It also instructs to turn the compressor over 10 revolutions, to get the oil out of the compressor head, with the service port UP. I've cranked and dumped and cranked and dumped for a LONG time and all the oil I can get out of the new compressor is about an ounce. The system is supposed to hold 9 ounces (266 cc) total. Am I supposed to pour 9 ounces directly into the compressor??? I'm a little confused here. It happens to us older folks sometimes. Can someone help me with my quandry, please?
The oil is in the remainder of your system If you look at the chart from super cool products, you'll notice the site gives you an approximate of oil left in the system in each component (evaporator, accumulator, condenser, lines and pump). If only one ounce of oil came out of your pump then put on ounce or maybe a tad more in.
I put in 7 oz of oil in my NEW pump but only drained 6 oz out of the NEW pump to replace with higher quality PAG 46. The rest I dumped in the condenser and accumulator. The new OEM pump claimed to have 7 oz in it, but I could only squeeze out 6.
When I removed the old pump, I did not check how much oil was in it and since it came out with both lines attached nothing leaked out.
ONE BIG PIECE OF ADVICE....absolutely replace your orifice tube filter/valve while it is open. This is the major cause of headaches in this system.
I have only been able to squeeze about one ounce out of the NEW compressor. I haven't gotten the old one off yet. The new one was supposed to come prefilled. After reading your next post, I'll wait until I get my old compressor out and measure what comes out of it and go from there. Thanks for your reply, Joe.
What's in your new compressor is oil to protect from rusting or dry rot. That just gets dumped; it doesn't matter how much is in it.
In general, the AC system has a set amount of oil, and the manufacturer, during the design process, takes a system apart and measures how much oil remains in each component. Often an amount is given for each component that is being replaced. Or they tell you to drain whatever is in each removed component and put the same volume into the replacement part, which I have for our Lincoln LS. If you add all the oil volume designed for the entire system, you will have excess oil.
I agree with replacing the orifice tube and accumulator while in there.
My accumulator starting coming apart internally and I believe that led to my hot temps only while climbing. The system worked well until I held constant RPM's and raised the system temp....or it would just flat out block the flow.
Use this chart (or interface with your specific year) to clarify how much oil is left in each component after disassembly. This along with what comes out of your OLD compressor should put you in the ball park IMO.
TBH - I am surprised that anything changed in the hardware. I guess that is why I saw it to read (at first) as an update for 04 and up (knowing that Tim has an 04 like you do). In fact, like Tim, I previously thought it was for all years. I had to expand the file view to clearly see it stated for 05 and up (these old eyes have seen better days, lol).
After detaching both of my retinas I am lucky if I can see my glasses to put them on.
Really not that bd just fuzzle some in the left eye. The right one is nice and sharp.
The left one took most of the damage.
I am looking for some A/C parts for the 2012 Escape I have while the truck is waiting on the engine.
It seems that the condenser took a hit and needs to be replaced ASAP.
I was looking at prices and hoped that someone might have some discount codes that they can share.
Also any recommendations for good quality parts. I wil get the receiver/drier from Ford as that is not a
high ticket item. The condenser is silly priced on the MSRP and not much better for the dealer.
Then when the engine is getting close to it's time for install I will be putting a mostly new system
back in. It will be getting a new compressor and drier along with a fresh orifice tube.
Thanks for the help.
P.S. Some Of These Small Jobs We All Seem To Have Going On Would Cost Us An Arm And A Leg At Full Price.
Ad that is not counting orifice tube coolant leaks or other itens.

It's safest to baseline (flush) any system when you have a situation with indeterminate levels of PAG. Overfilling doesn't "harm" the system per se, but will reduce the refrigerant's ability to cool. The problem many systems out there have is people dump dyes (typically suspended in PAGs) into their systems over time and the effects (buildup of oil) are like getting radiation (effects accumulate over time) -- A/C system loses efficiency over time.
Baseline first, then remove the high side service port schrader valve, use vinyl / poly tube (approx 1/8" or so) connecting one end into the high side service port, the other in the PAG container, then pull a vacuum on the low side and the oil will flow into the system.
