Use a vacuum coolant system filler(airlift) the right way 

This guy's attention to detail and thoroughness is what's missing in most shops.

Finally! A person that uses this tool and primes the feed line. I cannot tell you how many videos I watch where people use these tools and I watch the air in the empty line get sucked into the cooling system when they open the valve to refill. Thank you.

Best video on the internet describing how to use this tool. Thank you.

Good concise video, perfect amount of good info without any fluff

Thank you for the tutorial. Where has this tool been all my life?

Nicely done. Thank you for sharing your knowledge.

Well explained Mario. We have a similar one at the shop. That weight is a great idea. Makes life easier. Thanks for sharing! 👍

Great video! Thanks for sharing

Got the OEM Tools version of this. Cant wait to use it. Thanks for the video.

Fantastic video on this tool. Thanks

AWSOME! Demonstration, great info 👍

Thanks for the awesome demonstration Mario! That is the only way to fill cooling systems, because it is so clean, quick, and like you said, the only way to make sure it doesn't have any air in the system; especially when filling up the newer pressurized systems. Our shop has an Airlift, but it doesn't have the ability to setup the vacuum and feed hoses simultaneously; so that's really cool to be able to prime the hose as you showed and prevent that bit of air from getting in initially. That's a really great tool for the price and I think I am going to pick one of those up so I have my own.

Awesome video! The weight at the bottom of supply hose is a great idea that I will now implement myself , thanks!! One thing I did notice I do differently is turn the vehicle ignition on and set temperature control to hot and fan speed on Incase of any temperature control valve in the heater hose. I can’t take credit for that idea though as it was isn’t the instructions of my air lift , lol. Keep it up!

Super mario thank you for the informative presentation and tips !

A very useful tool for today cars. Nice demonstration.

I always look forward to your videos. A very nice presentation. Thank you for sharing.

Super. Great teaching!

Great video very helpful! Thank you!

Great video. I love your professionalism and attention to detail. I once had a Mazda that used coolant once a week. I couldn't find the leak but got a small whiff of coolant occasionally . Eventually, I parked it on all kinds of angles and squashed the hoses as much as I could. A tiny spot of green appeared at the bottom of the timing cover. Water pump bearing was leaking but only when parked just right and only for a few minutes as it cooled and sealed. It was the first time I'd seen a pump behind the timing cover. It had been pooling slightly in the bottom of the cover and evaporating without dripping at all. Now I've seen it often as they are mostly like this these days. First time had me going crazy!

Thanks Mario, another great learning video. Happy holidays.

Vaccum fill is an awesome tool. Use it every day.

Great video Mario! I love schwaben products.

Awesome video bro very well explained. I like to make sure my thermostat opens, and fan turns on before I test drive if possible then after a good test drive I let it set for a few hours top it off drive it again double check my work and ship it.

Its on my list of things to get, just did a t belt WP on my civic and got air pocket ( maybe head gasket and I will use the pulse senor in radiator to check). Those airlifts were becoming very popular as I left the in shop scene in 2011. Thanks for taking the time to show how to work it.

Thanks Mario, have a great Christmas

2:04 & 6:58 Best advices on this video. Thanks a lot!

Thanks...nice tips on pulling vac before tightening and filling hose.

I bought a cheapo filler off amazon & was not happy with it. So I put money down & got the Marvac from Cornwell. Day & night. If I woulda saw your video earlier I might have bought this one. You primed your hose a lot cleaner than I did. The weight is a slick idea. Thanks for your info!

Thank you Mario. Good job. Have a blessed and safe week. Merry Christmas to you and your family.

Great video

Awesome tip on prime in the system first. Just bought the Schwaben tool to do a coolant swap in my Porsche Cayenne. It’s a system that is extremely sensitive to air in the lines so am a little apprehensive but sure it will come out fine. Only crappy part is the cayenne doesn’t have a drain plug in the radiator so I have to pull the lower hose off and drain as much as possible and then vacuum the rest out of the system.

My co-worker has the snap-on version of this tool, I used it once on a 6 cylinder mustang worked perfectly, great tip on the supply step so we don’t introduce air into the system. Feliz navidad Mario

SUBSTANTIAL Super Mario Diagnostics Sharing what you know with us Thank you very much Super Mario Diagnostics From Nick Ayivor from London England UK 🇬🇧

Nice ! Just voted ! Your right by bringing it up to temp then letting it cool back down. When it cools down everything contracts leaving a void in the cooling system creating a vacuum allowing the coolant in the reserve bottle to be drawn into the radiator. After cooling down it Is a good idea to top off the reserve bottle too, to the appropriate level. Take Care !

great job just goes to show only when hot leaks amazing

Ur the only one I saw purging the fill hose Good job and advice The company should use u on how to do this correctly EVERYONE says that fill tube is minuscule U did the air evacuation the correct way CHEERS MERRY CHRISTMAS THANKS 🙏

Thanks for the info and video sir. Just bought one myself but i don’t believe i got my car drained as good as you did.

If the vehicle can sit overnight or 8 hrs or so, i always prefer that. I have topped off after test drive and letting cool off, but check overflow/degas the next morning and its a pint to a quart low. But of course you don't always have that luxury or time. Good video man and good job on finding the leak. I love that tool myself!!

Good idea on the weight. Thanks for the tip

Nice demo Mario. I was just thinking yesterday I need a coolant vacuum tool. Merry Christmas to you.

Thanks Mario

Good job. I have the same tool.

Great stuff Mario. I was looking for a link to the tool in the description

good job thanks 🤠

Pretty cool tool, especially for the price. A coworker of mine turned me on to the Matco one and I love it. No more filler funnel and waiting for bubbles to stop in the old school coolant funnels that screw on the radiators! Also, I'm stealing your weight idea, as well as priming the filler hose. I never thought about small amount of air making that much of a difference. The directions on mine didn't say to do that, but it makes total sense. Good tips on finding the coolant leaks too! Voted for ya dude

Awesome kit you use!! I use the snappy one , it amazing especially for the hard to bleed systems and I do the same I test drive 5 to 10 miles and recheck for top off. Big big help on Camaro's

Thanks!

I have this tool but never thought about priming the tool good tip. I might have to redo this on my s13 as it keeps overheating even after doing this.

Good vid

excellent

Great video, as usual, man. The only thing that I would add is that I find that it's beneficial to place the coolant supply container higher than the fill point of the car. Helps it fill more completely. Also, it helps to _completely_ drain the cooling system. At my shop we specialize in Porsche where many of the models have the engine in the back of the vehicle. This means they have to pump coolant through lines underneath the car to the radiators up front and there is are many opportunities for air pockets to form. There are also several points that require hoses to be pulled off to drain out all of the coolant. Failure to do this causes incomplete filling and overheating on the test drive. Also, some Porsche's require a scan tool to run a function to help bleed the cooling system, so always check the repair information. Most cars do not have these kinds of issues, but I thought it was worth mentioning.

i use one too, they are great.

Voting for you. Hope you win....

You guys are lucky to live in USA 🇺🇸, we here in Australia get screwed by the government, then businesses and individuals. Everything here costs at least 3 times of what you pay in the USA 🇺🇸.

That tool or similar is required equipment if you work on VWs or Audis. It is nearly impossible to get all the air out of the heater core without the airlift. The vehicle may run fine and the engine temp will be normal, but there will be no heat in the car because of an air pocket in the heater core. Thanks for the video and tips.

Gone are the days of using a garden hose to fill a radiator. But I don't mind buying a tool if it does the job correctly. Now with this video I have no reason to fail. :)

Really good video with the OEM coolant tool. Is it possible to explain how to alter the tool to also pressurize the system as you stated at the beginning?

i fucking love this video man, i feel way more comfortable about doing this myself! thank you!

Does the thermostat open under this conditon?

Place the bucket ontop of the engine, makes it easier then at the end dont clear the line use it as a syphon to top it off! Works awsome that way

Interesting. I've never used one of these. How much do you typically have to add after filling with the tool? Have you ever had the vacuum cause issues components of the cooling system? I'm imagining it cracking brittle plastic barbs or sucking in RTV from a fresh gasket. But I suppose those things are all rated for pressure, so vacuum is really no different.

Should the bleeder valve be opened during this procedure?

Can you make a video of you using that to pressure test a system and also how you made it

gracias

What psi should be at the compressor VS the psi at the top of the tool gauge? I tested a similar tool but I never saw the heater core lines compress only the bigger lines at the radiator and pressure help at 24psi. Makes me wonder is the thermostat never opened.. thx

Voting for you too win.....

What if we use the tool to vacate the anti-freeze is that alright to do? Versus draining and collecting from the petcock valve.

so i need to drain the coolant first before pulling vacuum? i can't just use the tool to drain the coolant too?

Para ello se requiere una bomba de vacío vd? De cuantos caballos ?

Hello Mario, I replaced water pump on my 2010 Fusion hybrid and now car is overheating, heater blowing cold air, do I vaccum both coolant fill reservoir ( EV and gas motor) thanks

Just did a Chevy Volt battery pack. Vacuum evac is required on batt cooling system,while GDS 2 does system bleed pulsing coolant pump.Takes about an hour.

Great vid thank you, just two points, thanks for dealing with any coolant left in that won't drain out (no-one else seems to) 2) How does it pull coolant/vacuum past the thermostat? Thanks

Good video, Mario. I had the snap on version, that I probably paid 3 times for. And for the most part, I only used one brand of coolant with it. But I never cleaned mine out and the coolant ended up drying and damaging it. So yes, like you said, make sure you're cleaning it afterwards!

The first vacuum filler I got was a universal type like that with the rubber plug, but the ones that use the pressure test adapters are way better. The Cornwell one is the best. You have to have adapters for every car, but it's not really that many. Most techs have their own pressure testers and fillers, but I actually feel like it should be the shop's responsibility to buy the master kit for adapters. It's really expensive and we already have to buy so many tools.

Very nice video Thank you. I know you posted the video in 2019 , and you did a great job being detailed about all steps. Someone asked you about the modification you did for pressurizing and either you missed the question or didn’t wish to respond. I am wondering if the modification included adding a 1/4” female/female/male 180 degree valve ahead of the Venturi system? Best,

Why my vacuum needle never go above 20% but when i turn off the air feed i have no decay?

That was a great video, very informative. I put a Subaru 2.5 NA SOHC motor in my 71 VW Fastback and haven’t been able to get the air out even with the vacuum tool. You explained how to prime the line and I think that’s where I have been doing things wrong? Definitely going to prime the line next time. Could I be doing anything else wrong? Thank man!!!

We test drive and recheck as well. We park cars and leave hoods up to remind everyone

Is it best to hook up the unit to the radiator fill hole or the overfill tank?

Just wondering. Would the pulse sensor show vacuum on the cooling system ?

Do you have heater on heat mode before you shut vehicle off to pull vaccum on cooling system?

Stupid question, if I want to take the coolant that’s actually now inside the system, can I use this tool to , like to pull old one/push new one?

👍👍

Try turning key on engine off and turn heat on low

can this be done with coolant in the system or do you need to fully drain it first before doing this?

Hello Super Mario! I bought this device and have a few dumb questions. 1. Should i drain all the coolant out first before using the device or this device can drain the coolant through the vacuum? 2. Can this device vacuum all the coolant out of the engine? Or should I have to do something first like warm up the engine before? 3. What is the pressure in the compressor before I hook it up on the airvac refiner? Great video. Thank you in advance for your help!!!

Need to mention one big key feature of this tool. Gauge on top. Can pull a vacuum and watch to see if it drop the vac and if it does you have a leak. This has saved my butt many times. I get pulled away from the car. And forget to tighten a hose clamp. Or a gasket didn't sea. All without oone once of coolant lost.

One thing you do have to keep in mind is cracking or pulling a seal in on radiator side or top tanks on rads or cores with age when using the vacuum fill. Sometimes you should break out the big funnel if things are looking iffy.

Great explanation! But I must say that air hose has seen better days lol

How do I use this tool without an expansion tank? All I have is a radiator, with a plastic overflow tank.

Out of curiosity, would a home compressor have enough of a tank to use one of these? :)

Great video as always. If you dont mind me adding only thing that can be done better in my opinion is to slide some fuel line over the jaws of the needle nose pliers, it seems to help the sealing process and dosnt leave jaw marks on the overflow hose👍🤙

Can I remove all the old antifreeze with this? I can only drain 4 of 13 quarts from the radiator drain. Thanks

Did you have to use a pry bar on the frame to push the motor a bit to make room for the water pump to come out? Lol I've done a few of those and that's the only way I've been able to do it. Great video btw

I use my vacuum filler on every single coolant related repair I can. So much faster that trying to bleed it out any other way.

Do you use a refractometer to check the mixture ratio?

Just confirming - it's air blowing into the device but due to the valve construction it ends up creating a vacuum?

You mention that your gauge is inaccurate ? are you concerned you may be pulling too much vacuum on the system with unregulated shop air and stressing hoses etc...

How can you vacuum and the car is cold? The thermo is closed so you vacuumed the lines before the thermostat not the whole line ..
