Draining/Refilling compressor

wesleyn on Tue July 08, 2008 10:00 PM User is offlineView users profile

Year: 2002
Make: Ford
Model: Focus
Engine Size: 2.0
Refrigerant Type: r134a
Ambient Temp: 90
Country of Origin: United States

So since I need to remove my old oil to refill the system how do I go about that? Also, how do I find out how much and what type of PAG oil I need? Doesn't some go in the compressor, and also in the condensor? Thanks again for everything!

2002 Ford focus need 26 Oz r135a and 7Oz PAG46 oil.

You need totally flush the compressor and add 3.5 Oz PAG46 in compressor and 3.5 Oz PAG46 in new drier.

Pull a vacuum and recharge it.

good luck.

And I put oil in the reciever/dryer, but not the condensor? Just pour 3.5 ozs into the drier before I install it?

Sorry , it is R134A not R135A.

The whole system need 7 Oz pag46. half in compressor and half in dryer.

You do not need put it in condensor.

Okay, and if I had just a pinhole in the system for a month or so, do I HAVE to replace the reciever drier or can I change the compressor oil and the drier oil and pull a good vacuum on the system? I wish I could just replace the condensor, and then vacuum the system and charge her up, but I guess I want it done right the first time! Thanks again for your help!

If it was me, I will replace a new dryer since the system is opened for one month.

"I want it done right the first time! "

If It was me:

1: buy a new dryer.
2: buy new condensor(you can not re-use the pin-whole one,, right?)
OR go to JY and get used one for 20 bucks and FLUSH IT TOTALLY.
3: Buy a new O-ring set(Advance part have it for 10 bucks.)

Then:
4: flush the compressor using PAG46 for 3 to 5 time untill you see the new frssh page46 oil out the compressor. Then put 3.5 Oz in it and replac the old 2 O-ring .

5: replace the condensor and O-ring.

6: FINALLY, take the old dryor out and put 3.6 OZ pag46 into the NEW dryer and install it quickly.

Now the whole system is closed and ready to pull a vacuum.

You can do it youself OR ship it out.

If you want DIY,

7; pull vacumm for 40 to 50 minutes. Then close the low side and high side and wait 10 minutes to see if there is any leak.

8; IF leak, .......:-(
9: if not leak, Just open the low size and add 26 Oz r134a .

!0, let the engine run in 2000 rpm, and chek the low size (around 20-30 psi )and high size(around 200 psi)

good luck.

I am sure you want to kill me by now, and I do appreciate your help. Do I just turn the compressor over and over until the oil is out, then fill it up and repeat, etc? And I do not need to put any oil in the condensor? Thanks again.
