Injecting Oil in a Auto Air Conditioning System

[@nalvarez3505]

nice video sir thanks for that, how you check the oil level?

[@FireHorse11291966]

Rich, I was looking through your videos and thought, you have such a great library of videos. Oh yeah, and I still tell the guys up at the auto parts store that your my mechanic. I can't remember the last time I've taken our cars to the shop lol

[@RichpinTv]

Wow great story, thank you for watching my videos.

@@RichpinTv Hey, Richpin, had a question. Is a 2002 Saturn SL2 DOHC 5 speed manual compatible with a 1995 Saturn SL2 DOHC? I found one for sale for under $2000 and I want to swap transmissions from the Automatic to a manual, thanks. I always appreciate you're informative videos. :)

You put more oil in the injector than you need, extra to purge the air. Put the hose over the original container, holding the injector and hose as vertically as you can, screw the injector to the 1/4 oz mark. Hook it to the low port and screw it all the way in.

[@VeritasInsights]

Very smart to bleed the air with your special setup there. Wondering how I can so so without an old line. Either way you gave me ideas.

[@Swenser]

After the oil gets sucked in, you are left with vacuum in hose and container, right? After switching off engine, the gas will flow into the vacuum part, right? Would it be better to detach while running to avoid gas loss?

If I’m replacing the evaporator on my car, do I install everything, vacuum the whole system, then inject the oil? Or can I inject the oil into the evaporator once installed, connect the lines and subsequently vacuum the system? I ask because the service manual on my car states to add oil to the evaporator when replacing it, but it doesn’t say when..

[@roadstar499]

What about using the oil in a pressurized can with a ac manifold vs this method? I already have a manifold...I just want to add a little to keep compressor working..its just a little low. Thanks

[@pomdigz9893]

Nice! Thanks for your wisdom... More please?

[@RichpinTv]

You got it!

[@petar443]

U said in a previous video , that after injection oil you will again test the volume with the autel oil tester to see if the oil amount is correct. You said that again. Are you goint to make part 3 then? This tool, and the tester look good tools.Seems to do the work

[@RichpinTv]

I should have tested it and included it in this video.Now that it is getting colder the A/C is not on my radar but i will see what i can do..

[@fredf.5901]

Thank you for this AC hack. how do you know that oil is low in the system, how do you measure oil in the system? Q: my Denso type: TSE17C system leaked and charged r134a and working but I'm hearing low rattle noise coming from ac compressor , do you think it is because of low oil or something else? and if so how much oil can i add? Thank you

[@JetFire9]

Replace your compressor now.

[@khaledq8bloshi306]

Try first to add 20ML to 30ML of PAG 46 oil when the ac is running... If the noises gone then you are fine otherwise unfortunately you must replace the AC compressor

[@thisisyourcaptainspeaking2259]

Specified ounces of oil charge is a volume, not weight.

[@enigmasvids9615]

All a bit too complicated if you want to add dye to determine leaks. Note that If you're injecting dye into the system...then there's obviously a leak. If so, it would be advisable to inject the dye when the system is depleted of refrigerant. As well, don't worry about injecting a small quantity of air with the dye as you will have to vacuum the system down prior to adding the correct refrigerant for the particular system. You then require a UV light and the appropriate glasses to view the leak. Most of the equipment required is available on the net at very reasonable prices for the DIYer.

[@Mike_44]

One last question, this oil you’re injecting into the low pressure side, it goes back to the compressor or through the expansion valve to the evaporator?

[@khaledq8bloshi306]

The low side port its Return line from the evaporator directly to the compressor. That's mean the oil will going to the compressor frist.

[@Mike_44]

@@khaledq8bloshi306 Thank you.

[@casperguylkn]

How can I get that tool? the stuff I bought doesn't charge as quickly for my Saturn 99 SW2. I bought a cap and a hose with the gauge on it. Like you, I started small with a 3oz can but it was filling really slow. Thanks. Love your Saturn videos.

[@RichpinTv]

I bought the tool on Amazon if you can not find it i will see if i can find the part.

[@CesarGarcia-zf5ce]

Great job, sir... 👍

[@jasonbradford1053]

Good job nice idea with the fitting

[@RichpinTv]

I'm glad you like it

[@olenaerhardt7725]

@3:45 Just brilliant idea to remove air fm the injector. I need help w/amt of oil. Can someone solve this arithmetical puzzle from the Shop Manual? It states in the Manual (car is 2001 Saturn SL2): The Saturn air conditioning system requires 150 ml (5.07 oz) of PAG compressor oil. Service compressors have 65 ml (2.20 oz) of PAG oil installed. New oil quantities must be added to the system during component replacement and conditions stated as follows: With no signs of excessive oil leakage, add: Compressor: Remove, drain, and measure oil. Drain the replacement compressor. Add the same amount of new PAG compressor oil drained from the removed compressor to the replacement compressor. Evaporator: Add 67.5 ml (2.25 oz) of new PAG compressor oil. Condenser: Add 22.5 ml (0.75 oz) of new PAG compressor oil. Receiver-dehydrator: Add 30 ml (1 oz) of new PAG compressor oil. Open the R-134a source valve(s) and allow 0.50 kg (1 lb) of liquid R-134a to flow into system through low side service fitting. As soon as 0.50 kg (1 lb) has been added to system, start the engine, set the mode control to vent, the temperature lever to full cold, the blower speed on high, and push the A/C compressor button to the On position (A/C control button light On). Slowly draw in the remainder of the refrigerant charge 0.23 kg (0.5 lb). The total system charge is 0.68 kg (1.5 lbs). I'm reading all that information in my Shop Manual and don't get this: If the total amount of refrigerant oil is 5.07oz and 2.25oz goes into compressor, then for Evaporator, Condenser and Receiver Drier is left only 2.82oz (5.07-2.25=2.82oz). But if to add what is recommended for Evaporator, Condenser and Drier it will add up to 4.0oz (2.25+0.75+1.0=4.0oz), with the total in the system 6.25oz (4.0+2.25). How much oil on total is in the system: 5.07oz or 6.25oz? Where I'm wrong? I'm replacing everything besides the Evaporator and Compressor (I'll remove it and flush w/solvent though), those I'll just flush with solvent. No info on Refrigerant Oil under the hood or in owners manual, or in Haynes book. Thank you.

GOOD JOB riche KEEP making THIS Nice videos it is sumer is over but falls is here from now on we going to need the heaters keep us nice and hot haha have a good one see you on the next one

[@RichpinTv]

I got one more A/C video then we will think about the heater....good idea.

[@georgekopsias9159]
