Refill Coolant Systems the EZ Way! OEMTools 24444 Airvac and Refill Kit

- Refill coolant systems the right way with the OEM Tools 24444 Airvac and Refill Kit. Servicing the coolant systems on vehicles a couple of decades ago consisted mostly of just removing the radiator cap and topping off the coolant. Todays car engines and systems are not only pressurized, but they also have many other components included into the system. This not only provides more opportunity for failure of the system, but it also provides more places for air to become trapped in the system. Trapped air can cause catastrophic damage to your engine. Removing the air (burping) from the coolant system isn't the easiest thing to do nowadays. The best way to service the coolant system is by removing most of the air to start with. The OEM Tools Airvac system quickly pulls a vacuum on the entire system to start with, then the coolant draws into every crack and cranny on its own.

Most manufacturers recommend this as the service procedure. You should put your coolant mix into a 5 gallon bucket so you do it in one go. Doing it your way you allowed air into the system swapping between containers so pulling that last vacuum actually helped you. Id also swap that short hose on the venturi out for one you can put into the bucket so you dont get coolant mist all over the vehicle and motor bay. Great video
Does this pulls out all other coolant inside the system? I just drained the radiator
@@bernabetijerina7104it can. It's a coolant filler/evacuator. But to use it like that, you will need to modify the tool and add a fitting with hose on the vent side, so you can properly pull the coolant into a receptacle. Otherwise, you're just going to be shooting coolant everywhere out of the vent tube.
Every time you close the valve, the suction hose remains under vacuum and the air you introduce into the line swapping containers is has no effect on the coolant system. This is the way every dealer in the nation does it. These systems are not entirely air free. You just can't have big pockets that obstruct flow.
Am I wrong here? Did he hook that thing up to the overflow tank instead of the radiator directly?
@@matthewsalomone3800some cars are different. His tank is pressurized. Mine for example, RAM 1500 has a pressurized radiator cap. My tank is just a reservoir.
This is the best tool review on UA-cam
These are the bees knees for vehicles with EGR coolers! I work on heavy equipment and they require the cooling system to be refilled like this or you risk air locking the EGR cooler and burning it up. Not mention it voids warranties. Great video and demo!!👌🏾
On city busses too. My buddy that works for the MBTA here in mass said if you dont use one of these it can take 6hrs+ to do a coolant flush in them trying to get all the air out
Great video, but one thing I'd like to add is to use a 5 gallon bucket and dump the coolant into it, depending on how many quarts the cooling system requires. That way, you're drawing from a bigger container and you don't run the risk of sucking air into the refill hose. These vacuum pumps are the ticket!
Great video, no unnecessary content.
Straight to the review and demo.
Thank you.
I got same kit, never used it, thanks for explaining everything
very good sir. excellent video. I just came to that realization today. I replaced my Radiator on my 2006 3.5L malibu maxx. I did not prime mine line AND fortunately there is a coolant bleeder valve on the Malibu. I opened the bleeder valve and no coolant came out. I took the cap off the surge tank and poured in about a pint more till coolant came out then bleeder then closed the bleeder. so it was the air I drew in. Actually vacuum filling the coolant is the same practice as pulling a vacuum on an AC system. After you have the vacuum, you attach the tank of refrigerant then you purge your line to the regulator of air.
Thank you very well "how to use it" explanation, just ordered mine
Thanks for the video. It explained how to use it much better than the directions that came with it. They sucked. They referred to the same valve with two different numbers. How hard could it have been to stamp a number on the plastic handle. I realize I am on a tirade here but nowhere in the instructions the manufacturer gave did it say you needed a vacuum pump. It referred to "shop air." Thanks for clearing it up.
Thanks for the demo and tips!!!!
These things are awesome. I got an older snap on one. Makes coolant flushes so much quicker and easier. The older snap on one i have seems a lot smaller. Its basically just straight across with a guage in the middle of two ball valves and hoses. No adding the extra venturi since its part of the tool already making it a lot more compact. I usually jus put all the coolant and water ina bucket so dont have to keep stopping to switch the bottle
Yes, most people do just use a bucket or larger container. We thought putting the smaller jugs up in the camera shot would be more effective in the video. Thanks for watching.
Do you use this tool to evacuate coolant for the coolant flush ?
@@4Jackson yes
Might have to invest in this.
Thank you very much excellent video. Just bought one from Amazon and I’m getting ready to do my car. And one of my concerns was the collapsing of the hoses.
Did you use it on radiator or reservoir?
You are awesome! Excellent video!
went and bought one second i saw another tech use one 😆 such a nice tool
The vacuum is wonderful at showing SOME leaks. We have had a couple situations(both with F150 pickups) where they hold a vacuum perfectly with no loss. As soon as you do a pressure test… the leaks rear their ugly heads. 👹 We usually just go ahead and give attention to that joint closest to the bottom of the coolant reservoir… that joint is always a headache. On my personal F150 I noticed a slight coolant smell. Yeah it was a tiny leak at that joint. It was the first place I looked. 😂 well… I grabbed and wiggled the joint and the leaking stopped. I was on a road trip at the time and didn’t have time to worry about that leak and fixing it properly. Well about every two days on this trip it would start to leak a tiny amount. I would just wiggle the joint and it would seal back up. After about a week and a half of doing this… the joint never leaked again. It’s been three years now and it still doesn’t leak. Not sure if the O ring just need to seat properly… or maybe it had a twist in it. Idk. But she’s been perfect and I’ve always wondered if those customer vehicles could be fixed the same way. Unfortunately I don’t have that kind of time with a customer vehicle and they get fixed properly. Just always remember to also do a pressure test along with the vacuum test. Pressure can show things vacuum doesn’t… and vice versa too. Cooling systems are crazy nowadays. I miss the old systems it basic connections. These newer style connections can be a huge pita.
Vacuum is a terrible method for leak detection. Especially on a system with collapsible rubber hoses.
Always have a pressure tester on duty for a final leak test when you fill the system. If you own this Venturi tool, no worry about losing coolant if you have to open the system back up, because you can just suck it back out without leaking a drop. 😉
Awesome Video!
Excellent. Do they make a unit that removes old coolant as well? Thanks.
I'm getting one of these 👍👍👍👍
What a great video! Nice tool.
I'm worried about the vacuum damaging the radiator core or hoses.
Havw you ever had any problems when using a vacuum refill tool like this one?
Do manufacturers give a safe vacuum pressure limit?
Thank you in advance!
This is a very helpful review of the tool. Very thorough, and helps me in my decision to purchase one. One observation. Instead of drawing the coolant from the 1 gallon jugs, would it have been helpful to premix the coolant in a 5 gallon pail? Then, you could avoid sucking air between jugs. Plus, it would be a little less messy.
Thanks for the review. I'll be ordering one soon.
Yes, on the 5-gallon bucket, and I believe we even mentioned this in the review. It makes much more sense to just premix and pull it all in at once. Thanks for watching.
That is the kit that I have...🏁👍
6:00... glass fiber-reinforced handles on the ball valves...she's a stout unit TJ
When you use your compressor, obviously turned of, and filled first, do you change the air amount on compressor lower?
Great video, question will this extract coolant when pulling a vacuum?
Looking at this or the Airlift. Which one you highly suggest. Base on Quality
Do you drain coolant out first?
hii let me give you my trying experience with many times i never had any problem with it and it is great 👍 turn the engine on and try to press on hoses after 1 minute start fill up slow and try many times to press on hose until nerly filled up wite until it get normal temp try to add mor if it need drive slow next day try to check and go fo ever
I bought a crappy 35$ version of this tool on amazon last week. Total garbage, but I knew the concept was good. returned that one and bought this one. All good now
How did you drain all the old coolant out? It seems the initial vacuum won't draw any old coolant out. If only draining from radiator, only half of the coolant comes out. My approach was to fill and drain the radiator several times using distilled water. At the very last drain, at least the half still in the engine are basically water. Then use this tool to fill the 100% coolant to top it off and purging the air in the same time. Does this sound good to you? Thanks.
In the case that you over fill can't you just suck the access out instead of vacuum and fill again? Nice video
I've had two of them they work great but the vacuum gauge on them is on the cheap side and if you push down in it by accident it bends the if you pop it back up sometimes your ok other times it bends the gauge my only problem is I wish it had a nice heavy duty gauge
What do I do if I want to empty the current coolant with this?
hi, can i use this Vacuum out the old coolant or i need to drain out coolant first than vacuum tne system.
Can you use this system to top off the coolant by not pulling as much vacuum. Or is this only for completely empty systems
Curious, when draining coolant for a vehicle usually the coolant in the block remains, is this tool capable of pulling that coolant out?
You need to turn on the heater mode before you drain the coolant, so that coolant in the block also gets replaced
Some people commenting on can it take all the coolant out or empty the system totally!? Im not sure it can !? But if you empty your system & flush old coolant out the original way with water until it the system runs clear & clean , you will of coarse have a little water left in the system but that will only be a very small amount which will just mix with your coolant mix when you add this tool to the system, so you wont have any possible old or contaminated coolant running around the system .
The old saying is good preparation is key to a propa job completed well!!
I always totally clean the system out always & this helps prolong the life of new coolant your putting in . 👊🏼✌🏼
Wouldnt the vacuum step pull out any old coolant left in system?
I agree with you totally. In his demonstration, he did not show how he emptied the system.
What is the psi setting for the air hose connected to the venturi?
About how long does it take to draw a vacuum down to 24? I used this for the first time on my Explorer and it took about 25 minutes, the system held the vacuum so I don't believe there is a leak.
Can you drain the old fluid using this thing?
purchased and used tool, having issue where when trying to create vacuum, the needle bounces like crazy as opposed to a smooth gradual increase any idea why
Can I ask a stupid question? Why can't you just warm up the engine, then disconnect the tank return line and take it to a big bucket. Start the engine and keep topping up the tank with distilled water til the return runs clear. Then start adding concentrate until the correct amount is added, and run a bit more until the fill level is correct, then stop the engine and reconnect return line.
How do you use this to burp an already full system, without pulling up all the fluid already in there?
Great video! Can this tool be used to simply bleed all the air out of a filled coolant system without having to drain and refill?
not if there is a air pocket trapped in a part of the system that is higher than the point from where the vacuum is being pulled
Is this after the coolant system has been drained?
I have used mine a few times. Older and a little differant
Will you recommend it to me?
Do you have to get to 25 psi? I pulled vacuum and only got to 22 but the system held there.
I just used this for the first time and it is a wonderful tool. My only concern is this, when using the tool at the reservoir, it fills the jug past the"full" mark. I've watched a few videos and haven't heard this mentioned. My car was fine for two weeks after using this tool until I decided to syphon the jug down to the 'full' mark when cold, after syphoning my temp gauge would get close to overheating in traffic (guess I somehow introduced air while syphoning). I did it all over again and left the jug alone.
Did you hook it up to the radiator cap?
On vehicles with a degas bottle it's common for it to fill it to the top. This is because that empty space is also under vacuum. Either cut the tool off as you reach the max line, or use a syringe and set it to the proper level once the tool is finished.
Vacuum pumping coolant and heater core system out of your car cooling system
Vacuum is a terrible leak detection method when you're dealing with collapsible rubber. Pressure test is still the sure fire method. Outside of that, these refill tools are awesome.
What machine do I need to provide air flow to the venturi? Can you drain the coolant first with this tool before refill? Thanks
1. air compressor. 2. Not sure.
needs to have a shut off valve in plastic line from plastic gallon of antifreeze so you dont draw in air when jug runs dry while filling
I’ve used mine multiple times on multiple vehicles. Have you ever had a problem when refilling where the gauge doesn’t make it to zero? Vacuum holds great, starts pulling in coolant and will pull down to a little under 5 psi and holds there. Coolant seems to be full and running properly but I hate that I can’t get this thing to hit zero psi.
its because of the vebturi beung valved off with vacuum. They're still there's still residual vacuum in the little Venturi assembly if you disconnect it itll go to zero but it's not affecting you at all
Any idea what the shop air pressure should be ?
At least 90 psi
I have a different simple question, where does the old coolant go? Do I need to drain the radiator and the block first? 🙏
Yes in a bucket or suitable container
Is it possible to hook this unit up to pull air that’s trapped in the system WITH the original coolant still in the system? I can hear air trapped and cycling through my heater core and cannot get it out from the bleeder valve or opening the reservoir and running the vehicle
Did you try it out? I think I have air trapped in mine and was wondering the same thing?.
Can this tool also do a pressure test on the radiator cap?
no a seperate tool is needed and pressure check with the system full of fluid. thats how it will normally be.
I just purchased this tool to do a coolant flush on my 2014 ford f350 6.7 l diesel...i paid $120 not $80 for mine!
What I don't understand is what about the thermostat that doesn't have the little vavle to let air through
Exactly what i was thinking about! You have to let the car warm up in order to open the thermo first otherwise its useless
Do you need to remove the thermostat before using this tool?
No. If you did you would create air once you put it back in defeating the purpose. Good question though
Yes and make sure to remove radiator also
How did you make sure there was nothing left in the system?
If your car has a reservoir tank and a radiator cap do you put it on the tank or radiator?
Put it on the radiator and block the overflow hose going to the tank.
So you only need a compressor not a vacuum? (Answered yes as long as it meets the PSI and CFM rating of tool)
Do you empty the system first?
Do you have to open the thermostat first?
Also Wd-40 is not a lubricant when will people realize that
You need the compressor to create a vacuum with the venturini
@@glenduke4874 so a regular compressor works?
Yes. As long as it is big enough to supply 90psi. If it's a smaller compressor you can start then close the tools valve. Let the compressor build its pressure then start again. The compressed air blows straight through then creates vacuum on the T portion going to the cooling system.
@@glenduke4874 thank you for the reply
What i dont understand is that you used two containers to fill the system which caused you to stop & end up faffing about with the valves!
if you know how many ltrs the system takes then why didnt you just add the correct amount of coolant mix into a deep clean bucket then suck it in from the bucket?? No messing around & you get a continued flow .
People do not do the way this guy done it in respect of the two coolant containers!!
Everything apart from that discrepency was spot on tho.
it doesn’t work on my 3500 ram
This is cool and all, but how can you pull vacuum in ENTIRE system when the thermostat is going to closed…… 🙋♂️
Just use a vacuum pump. You will have to retool it no shop air
Some of the comments to this video are downright depressing. No wonder this country is falling apart.
Lol, some people just have too much time on their hands. Thanks for watching.
very poor video, the hose for extraction is to short should be long enough to reach a bucked on the floor, you only showed 2 gallons of consecrated coolant but did not show the 2 gallons of water installation on the vehicle , you said the system needed 4 gallons. you did not run the truck to see how far down the coolant went after the thermostat opened.
Video was great. You can’t fill in the blanks? Probably shouldn’t work on cars then pal.
@@edjohnson9989 some people depend on your videos to fill in the blanks because they don't know. Me I know ASE Master many years.
No my boss doesn't like those
because it charge at hour rate ?
You need a new boss.
I stopped watching this video because there are too many ads.
No good on a 2014 Civic.
