THANK YOU! I just replaced the low side Schrader valve and condenser/drier in my '01 Highlander, and I thought I made a mistake adding the appropriate amount of PAG oil before purging the system and adding coolant, but you answered my question! My AC held steady -29 vacuum for over an hour! 20 min left on the purge, then fill with 24 oz of R134a, which is according to official capacity specs, and my AC should be better than it's ever been since I bought this car 3 years ago.

This is sheer beauty. Glad I found it!! FYI,. I don't think this will work well on systems with TXV vs. orifice tubs, because a TXV system may not equalize well or at all, but I suspect on an empty system of any sort, if you can feel a vacuum at any specific port, you can use it to pull oil into the system using this method. I have a few bottles of PAG46 oil with dye and 2 R-134a systems I need to work on, but my father-in-law's Cadillac has so much crap covering up the engine guts that I am really not looking forward to digging into it, but I know it has a slow leak, and needs oil, 'cause his "mechanic" just keeps adding R-134a every few months, or when there's a complaint, saying that the real problem is too hard to fix, or won't be worth fixing... I'll get some dye into it (with oil), and see if I still agree with them about that part. Either way, the system will need much more than Freon if no one ever adds oil to it, so I'll try to save the compressor from an early death without taking everything apart. To all the armchair QBs who are ranting about bringing moisture into the system, go read a book, and avoid AC repair, 'cause you don't get it. The system was already open to the atmosphere, so the damage is done, and that's why you pull a deep vacuum on the system, and let it sit for a while - to evaporate the remaining moisture and remove it! And also why you do that AFTER doing this! I nearly bought one of those fancy oil injector tools from Amazon before I saw this, and I'm really glad I did!

That's one way of doing it but some units come stating the amount of PAG in the compressor. You drain what's residing in the old compressor then remove the residual from the new compressor to balance it out. Also, if your system had a freon leak, you must add oil to compensate. Around 1 to 1.5 oz. If replacing components like the condenser, accumulator or evaporation, you need to add 1 oz for each. As a general rule, you want to error on the side of more oil then less.

What I mean is this, using your way of adding oil on the high side: - close the high side at the manifold - close the high side at the port valve - disconnect the high hose at the manifold but leave the port valve in place but closed such that the high side hose is now just a loose hose connected to the high side port - run the vacuum, open the low side at the manifold but leave high side closed at the manifold - put the open end of the loose high side hose into a container of pre-measured oil - slowly open the high side port valve to draw in the oil, then close then valve once the oil is sucked in Did you add oil on the high side (instead of the low side) because it was closer to the accumulator? Thanks again!

Unless you have your vehicle hooked up to a professional auto HVAC machine, there's no way to suck it out. Easiest thing to do is replace the accumulator/dryer which holds a lot of PAG oil. Weight the different between the old dryer with the new and you'll know how much oil it contains. Figure around 1.5 oz or less of residual oil for the condenser, evaporator and lines. With the accumulator removed, you can blow compressed air through the lines to get even more oil out. Good luck!

Can buy 3 oz freon cans with oil. Noise may be your clutch wearing out.

My method is this using the small 2-4 ozs charged cans of oil. After the system is evacuated I introduce the oil via the HIGH side. Since the system is iin a vacuum it sucks the oil in fairly rapidly. This is with the engine NOT running. Similarly I introduce the first can of freon this way. Sometimes , depending on the car, you dont have to jumper the low pressure swith which usually prevents the clutch from engaging due to low system pressure. I then start the vehicle and introduce subsequent cans as a vapor ( can right side up) into the LOW side.

@hardlymovingpro

Thanks for sharing! There's nothing wrong with the way that you're doing it. The only suggestion I'd recommend is to introduce the oil via the low pressure service port that feeds into the compressor.

Before charging the system with refrigerant, you can buy 12 oz refrigerant cans with 1 oz of oil already added. The problem is, they're more expensive and you don't know what the oil weight is (PAG 46, PAG100, etc.).

The way I do it does not require removing the Schrader valve. Just leave both lines connected. Remove high pressure hose at the manifold and pull vacuum on the low side. Use the high pressure line to suck the pag oil. Then reconnect and continue vaccuming to satisfied

How do you know how much oil exists in the entire system if the system had a leak and was losing oil? Do you have to remove every single component one by one and pour out the oil to measure? Is there an easier way?

02 avalanche condenser damaged in fender bender. Replaced the condenser and accumulator. Vaccumed down for 1hr System holds 8 oz oil 26 oz 134a. I saw online that for my truck the condenser needs 1.5oz and the accumulator needed 3,so I put 4.5oz in. Is that too much? I haven't put refrigerant in yet it's not too late to drain it but that seems like more than other people?

I usually put in from 1 to 1.5 oz of oil for each component being replaced (i.e. accumulator, condenser or evaporator). 4.5 seems excessive. You can also weight the difference between the old accumulator and the new one to determine how much to add.

Auto ac units are designed to constantly circulate oil through the system. That is, the oil both lubricates and cools the compressor. The oil gets cooled when released with the refrigerant via the expansion valve.

Viscosity: PAG 46 has a lower viscosity rating of 46 centistokes at 40°C. Viscosity: PAG 100 has a higher viscosity rating of 100 centistokes at 40°C. Protection: This thicker oil provides more protection at higher operating temperatures. This is of what I found on the tech data about these two.

I'm assuming your replacement compressor came pre-oiled ... meaning that the additional oil you added to it compensated for lost oil in the condenser and accumulator. If you added around 1 oz, you should be okay.

No additional oil needed unless you replaced other ac components (i.e. condenser, accumulator, lines). Around 1 additional oz per component.

Have to hooked up with a professional ac evacuation/recharge machine to accurately purge and reinstall oil and refrigerant

I just replaced my compressor and forgot to pour the pag oil in before recharging. It requires 14 ounces. The new compressor has 3 in it upon purchase, and I added 4 cans of what I was told was pag oil and it should have added up to what I needed. After reading the back of the can, I found that it only contains 1 ounce of oil and 1 ounce of 134. So I only have 7 ounces in the compressor but need 14. Will this method work if it already recharged or do I have to evaluate the refrigerant before doing this method?

@hardlymovingpro

3 жыл бұрын

You may be okay. The 14 oz is the capacity of the entire system. So you have residual oil held in the lines, condenser, accumulator and evaporator. Approximately 40% of the oil is in your compressor. That would be 5.6 oz. As a general rule, add extra 1 to 1.5 oz of oil to compensate for leakage. That means add 6.6 oz to 7.1 oz for the compressor replacement. So 3 oz in the compressor + 4 oz from the 4 cans = 7 oz. You're right on the money IMHO!

Do you always replace accumulator when your replace Compressor and do you ever need to add oil to a none leaking accumulator when compressor is replaced?

@hardlymovingpro

3 жыл бұрын

With a compressor replacement job, I find it good practice to replace both the accumulator and condenser. If the condenser has any impediment in it's tubes, that'll prevent the normal pressure levels between the high and low side. Many condensers now have integrated accumulators. Accumulators prevent moisture build up in the system which can destroy your compressor. Good practice to replace them when the system is opened up.
