PAG oil capacity

AC Compressor crapped out. I am replacing:
Compressor
Condenser/dryer
Expansion valve

Only old component I am keeping is the evaporator under the dash.
I have flushed it several time to make sure all contaminates are out... as well as the main lines.

Can somebody please confirm the PAG oil capacity of the entire system? (My underhood sticker showing capacity came off several years ago when I was pressure washing the engine....)

FSM says:
5.6 in compressor
1.4 in condenser

But I can't tell what else I might need to add to the evaporator.

 

Assuming this is on the '11 in your profile, since you are in the 2nd gen forum?

 

YES. Sorry.
2011

 

I show oil type VC-100 PAG 5.5oz
refrigerant capacity is 22oz
Clutch compression gap Minimum 0.012", Max 0.024"

Also make sure you "vacuum" the system before recharging it.

 

Page 112 or so shows 5.5 oz of PAG 46, 22oz of R134a. For the whole system.

Are you looking at an FSM for a '09-'12, or an earlier version? 1st Gens appear to have the 7 oz range you are quoting.

Give me a vin number and I can get you every capacity you need. As for "flushing the evaporator" you might have done more damage than good. Passages in the evaporator core and condensor are wicked tiny. Flushing has become a thing of the past. It use to be ok when you could fit a 10mm socket through the passages. Not anymore. Evap core isn't hard to do. Just extremely time consuming. I've done 3 this past week. 1 in a f250 took me about a day. A 2004 exploder took me about 4 hours and a 2014 highlander took me a day. Make sure you add the proper amount of pag oil. Lube all the o rings at the connecting points with pag oil. Pull a very deep vacuum and charge it with the proper amount. If you don't have a vacuum pump or a way to charge it properly I recommend taking it to a shop.

 

Great post....

Shouldn't he also as part of the vacuum hold it to test leak down to make sure you have a "sealed system" otherwise you will contaminate everything and have to start over.

 

Of course. My recovery unit does this automatically after a vacuum. Slipped my mind since I'm use to the automated life

 

The "four seasons" link above states 5.5 oz complete system. But then it states you should still "Always refer to under hood decal as the primary source for refrigerant and lubricant information." (which I DO NOT HAVE)
Since this is an aftermarket chart... I do have my doubts.

This contradicts other info I have....
Per "2005+ Toyota Tacoma OEM Repair Manual" at link http://www.customtacos.com/tech.old/files/05FSM/repair.html
It states the following on different pages:
COMPRESSOR AND MAGNETIC CLUTCH
AC
INSTALLATION 1. ADJUST COMPRESSOR OIL (a) When replacing the compressor and magnetic clutch with new ones, after gradually discharging the refrigerant gas from the service valve, drain the following volume of oil from new compressor and magnetic clutch before installation. Standard: (Oil capacity inside a new compressor and magnetic clutch: 150 + 15 cc (5.1 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed when replacing the compressor)

AND

14. REMOVE COOLER CONDENSER ASSEMBLY (a) Remove the 2 bolts. (b) Lift the condenser up, disengage the fitting of the condenser lower bracket and remove the condenser from the rear side of the vehicle.
(c) Using a screwdriver, disengage the claw and remove the condenser upper bracket LH. HINT: Tape up the screwdriver tip before use. (d) Using a screwdriver, disengage the claw and remove the condenser upper bracket RH. HINT: Tape up the screwdriver tip before use. (e) Using a screwdriver, disengage the claw and remove the condenser lower bracket LH. HINT: Tape up the screwdriver tip before use. (f) Using a screwdriver, disengage the claw and remove the condenser lower bracket RH. (g) Remove the condenser. HINT: At the time of installation, please refer to the following instructions. If installing a new condenser, add compressor oil to the condenser. Compressor oil: RL-897 or equivalent Add 40 cc (1.4 fl.oz.)

So this would be 7.01 oz and then what ever else might need to be added to the evaporator????

FYI: my new compressor came pre-filled with 5.6 oz (I know I need to drain and refill it just to spec to make sure....)

Sorry for the doubt of the above posts... just trying to make SURE I get it right as I have different information from different sources.

THOUGHTS?

 

Remember.... Your compressor came pre-filled with oil for shipment purposes and in case some dummy operates it by hand. Once installed and vacuumed it will not

 

But then vacuum is not supposed to remove much oil from the system?

 

Vacuum removes little to no oil from the system

 

Yeah, that's what I read.

I came here because of this: I had A/C evacuated and recharged today (2012 Tacoma). The machine pulled around 3 oz. of oil during recovery (I was standing next to it and saw it). The guy said that's too much and it was probably overfilled - and he put back less (1oz? Not sure how much, should have asked). Should I be concerned?

The backstory is the compressor was replaced by a Toyota dealer 2 years ago after suddenly seizing up. It has been working ok since but never quite as cold as before. I have zero confidence that they did it correctly since they even did not bother to put port caps back. I noticed it only months later and replaced them.

 

Also - they recovered 1.2 lbs. of refrigerant. The specced max is 1.39 lbs. and that's what they charged it to.

 

So I just installed a new compressor on my '13 Tacoma but did not drain the new compressor of oil before installing. I am currently pulling vacuum on system before adding PAG46 and charging system. According to the parts distributor the compressor came with "some" oil for shipping purposes. Is there a way I can add an appropriate amount of PAG46 at this point without removing the compressor and draining it? I'm inclined to just add 5.61oz but realize that will be too much. How close do you have to be to correct amount of oil?

 

Bump, in need of some advice here. Reading around on these forums has me unsure.

From what I've read, 5.61oz is the total system amount of PAG oil for my '13 Tacoma. My old compressor did not drain anything. I would think that would mean I add 5.61oz less whatever volume came in the new compressor.

That being said....

My new compressor (which is Mahle brand, who I believe bought out Denso) says on it's label that the oil volume is 150ml or 5.0721oz. I'm not sure if that means that's how much oil came in it or if that's how much needs to be there after adding more. Also, Denso website seems to indicate their compressors ship with the correct amount of oil:

https://www.denso-am.eu/products/au...-compressors/practical-tip-on-compressor-oil/

So I am honestly unsure whether I need to add oil at all, or how much oil if I do in fact need to add oil.

Can anyone help me out?

 

Check your PM I responded to you in detail.

 

Thank you all for the advice. I have a 2010 tacoma, 4X4 V6 double cab. I am about to change out my condenser and the evaporator. It says to add 1.40z of the oil to each one the condenser and evaporator. The manual says (Oil capacity inside a new compressor and magnetic clutch: 150 + 15 cc (5.1 + 0.51 fl.oz.). I am a little confused because I though the total amount was supposed to be 5.6. Please help. Do I need to remove the compressor to drain and add the oil? Also, any advice to or issues that you ran into? Thank you in advance.

 

Hey, what did you end up doing?
I just installed a Mahle compressor but didn't check if it has any oil. I'm going to call dealer who i bought it from to see if they know if it comes pre-filled.

 

I BELIEVE that there is a typo in the manual on page AC-74, which is leading to all the confusion in this thread. The passage on capacity should read;

"Oil capacity inside a new compressor and magnetic clutch: 150 ± 15 cc (5.1 ± 0.51 fl oz) [variation of 10%]."​

Put another way; the compressor should be filled with between 4.59 and 5.61 fluid ounces of PAG 60.

Prove me wrong!
