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

[@andrewbaughn1738]

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

[@bernabetijerina7104]

Does this pulls out all other coolant inside the system? I just drained the radiator

[@LynxStarAuto]

⁠@@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.

[@LynxStarAuto]

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.

[@matthewsalomone3800]

Am I wrong here? Did he hook that thing up to the overflow tank instead of the radiator directly?

[@mannyfresh8504]

@@matthewsalomone3800some cars are different. His tank is pressurized. Mine for example, RAM 1500 has a pressurized radiator cap. My tank is just a reservoir.

[@fasteddie8225]

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!!👌🏾

[@jacksmith2315]

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

[@4663David]

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!

[@mcfly6667]

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

I bought this tool on Amazon about a year ago and did it on two cars - it was actually fun! No mess, and filled it right up! I only had a 5 gallon pancake air compressor but it worked just fine!

[@lazykbarranchoutdoors]

Dude i bought this years ago, was aboht to go buy a purge funnel and for i even had this thing. Watching this to learn how to use it first as i think this is what is causing my 2001 f150 ifs overheating issues. Youve earned a sub here, excellent and i mean EXCELLENT HOW TO USE VIDEO

[@TsunauticusIV]

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.

[@LynxStarAuto]

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. 😉

[@richphero106]

Curious, when draining coolant for a vehicle usually the coolant in the block remains, is this tool capable of pulling that coolant out?

[@freddyherrera8823]

You need to turn on the heater mode before you drain the coolant, so that coolant in the block also gets replaced

[@LynxStarAuto]

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.

[@jacksmith2315]

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

[@Shoptoolreviews]

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.

[@4Jackson]

Do you use this tool to evacuate coolant for the coolant flush ?

[@Mr.NEStalgia]

​@@4Jackson yes

[@Networkprofessor]

This is the only video on youtube that shows you need to empty the air from the hose going to the fluid. Every other video shows the stupid people running the air into the radiator. I don't understand how those people are not taking the time to make sure they are telling me the right things like this video. Thank you.

[@juliewoods6534]

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.

[@seaworthing]

hi, can i use this Vacuum out the old coolant or i need to drain out coolant first than vacuum tne system.

[@meTimetraveler]

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.

[@pw5192]

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 . 👊🏼✌🏼

[@pleach3921]

Wouldnt the vacuum step pull out any old coolant left in system?

[@DuckTomato]

I agree with you totally. In his demonstration, he did not show how he emptied the system.

[@RGV2300]

Between this one (oemtools), ares vac refill kit and the other one with a lot of radiator cap adapters, which one is the best? Maily looking for simplicity and how quick it is to get the job done. Im prone for the simplest ones with universal adapters because they are cheaper, and the tool sits over the filler neck. Which is better? Which kit is the life changer one? Im sick of refilling coolant the old way, is a waste of time, actually im now facing an intermittent overheating issue with an ecosport with the 1.5 3cyl dragon engine, which im pretty sure, is just an air pocket problem, because leaks are non existent.

[@JMSynthetics]

Great video, question will this extract coolant when pulling a vacuum?

[@robertclymer6948]

Oh God! How I wish! on my f-150 2.7L ecoboost, can only remove about half of the coolant or 7 qts at best if you jack up the back end of the truck.

[@robbiesz]

does it need high CFM shop air or does it work with the small home (2 gallon/ ~.9CFM) air compressor?

[@trappking8626]

Do you drain coolant out first?

[@robertclymer6948]

Yes, he did. Wish the tool would pull out old coolant as a closed system, you are only get about 1/2 the coolant out. The rest is in the Block etc.

[@DuckTomato]

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.

[@indiomechudo1]

Thank you very well "how to use it" explanation, just ordered mine

[@mondohamster5702]

Seems many unanswered questions re vacuuming ALL old coolant from system. My feeling is no, not all. Coolant in collapsible lines (hoses) will exit due to collapsing hose walls squeezing (like toothpaste). But coolant in hard spaces (block and metal passages) will not exit unless swept along by the remaining incidental air exiting a gravity predrained system. Have you ever seen a top mounted vacuum suck up liquid at the bottom of a glass container?

[@Michael-uo4jj]

went and bought one second i saw another tech use one 😆 such a nice tool

[@ax5017]

Looking at this or the Airlift. Which one you highly suggest. Base on Quality

[@burnetthopkins9583]

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.

[@Shoptoolreviews]

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.

[@RALTBOB1]

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.

[@brianreeves4309]

[@miq5000]

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

[@isaiahpalo2797]

Do you need to remove the thermostat before using this tool?

[@Hello_its_me_mario]

Yes and make sure to remove radiator also

[@butchtherhino8202]

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.

[@toolman1962ful]

Any idea what the shop air pressure should be ?

[@waltersweet4595]

At least 90 psi

[@SchwartzBOSS]

Can you drain the old fluid using this thing?

[@paulwary]

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.

[@OfficialDSFN]

What do I do if I want to empty the current coolant with this?

[@robertclymer6948]

I think it would only pull from the reservoir bottle if it evens does that.

[@mattiaconti8885]

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!

[@MegaNardman]

Cooling systems are designed to hold varying amounts of pressure already (depends on the radiator cap), pulling 24PSI of vacuum shouldn't be an issue for a healthy cooling system.

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

[@jontansgarage]

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.

[@ericmills6]

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

[@alyte11]

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.

[@jamalcole1985]

Did you hook it up to the radiator cap?

[@LynxStarAuto]

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.
