Tool Time: The Coolant Air Lift System

44 thoughts on “Tool Time: The Coolant Air Lift System”

1. Mr. O, I have a 21 Acura ILX. I drained the radiator. Filled it back up with spill proof funnel. Now I’m only getting hot air on HI setting? Not the fan setting, the temperature knob. I bled this thing for 3 days, to no avail? Any suggestions? Thanks👍

2. Does the system need to be drained to use this? Can it be used on a mostly full system to draw out trapped air pockets?

3. Does anyone know if you can use this to bleed a coolant system if it is already full with coolant?

4. Thanks for pointing out the “Venturi “ effect (1:18). No vaccuum pump needed to suck the air out.

5. Used one of these tools on a '88 Acura Legend. They're amazing.

6. There are so many people that are worried about the air in the hose. If you're that worried about it redo the vacuum and put more coolant if needed. Also there is no such thing as a perfect vacuum so there is still air in there. Even in space there is air, not very much but it's there

7. Could've used this today, had a Chevy Sonic 1.4L airlock on me, SOB!

8. I assume you must drain your cooler system am I correct

9. Can you use it on partially full system?

10. I never see anyone purge that gulp of air in the filler hose..hmmm..great video👍

11. What psi should my air compressor be when using the vacuum tool 🤔

12. How much air pressure is needed?
    Need to know if a portable air tank would work,
    or is a certain size portable compressor required?

13. I was today years old when i found out they say cripe in Avocado New York. Though it was just something us Northern Midwesterners said.

14. I'm noticing from all the other You Tube mechanics out there you my friend are the only guy that goes to the engine and back to the camera lens to speak to you viewers eye to eye. Very personal and effective way of communicating to your viewers. Makes me think that you are talking to me directly. Allows you to connect to all your thousands of fans on a one on one platform. You are a smart Youtouber. Cheers.

15. I’ve been a Heavy truck mechanic for years I wish I woulda found this method sooner 😂 no more bailing coolant from the pan and dumping it in

16. Isn't there a way to prime the coolant filler hose so the air in it doesn't get sucked into the system?

17. Thank you for explaining the venturi effect. you're the only one that has done that. Now I know I have to rent an air compressor.. or shop-air w/e since I'm doing this on a Mack dump truck. Thank you

18. Are you sucking air or pushing air in? I don't see any machine for doing this job.

    One sucks the best .
    One sucks the most .
    One just sucks .

20. Rocket Surgeon. Classic!

21. Does the vacuum hold the thermostat open

22. May try this tool on my 1990 ZR-1. Thanks, cool tool. 👍👍🏁

23. Does the bleeder have to be on/open?

24. Is the Ford 6.7 PSD a troublesome vehicle needing the air-lift?

25. may never see this post but really thank you mr o and your family dang good people . I am or now live in west tn. even though I was born in Ithaca the last child born in the old hospital across the lake then they moved it I drove by you town a lot visiting family never new a 3 bay shop could produce the quaintly of work and family life as your shop as produced over the years my cousin runs phoenix in Lancaster Pate Neff super guy may have towed you some cars any way thank you and thank your family.

26. thks I buying it today

27. Antifreeze always tastes like the coffee my wife makes me

28. I've got a '92 Camaro with the TBI 305, and only 97k miles…every time I'd have to drain the coolant for whatever reason, it gets what I'm assuming is an air pocket in it, and it seems like it takes forever to get it to burp enough to finally finish topping it off…and yes, it makes a huge mess as well…would ya have any ideas what could cause it to do that, and what can I do to get it to stop?

29. Where do you get those jugs?

30. What about the air that's in the hose before the first drop of antifreeze is drawn through? I feel that just introduced an air pocket into the system (similar to purging/drawing a vacuum on a/c hoses.) Is there a way to evacuate the hose before beginning?

31. I drain all that extended life antifreeze out of my vehicles. I like to use the John Deere coolant.

32. Does thermostat position (open or closed) affect this process?
    Great vids EO!

    Stay gold.

33. 3:49. Is it necessary to turn on the heater before doing the vacuum?

34. Aren’t you fancy with your little factory tool truck tool! I made my own “air lift” with an old radiator cap and some brass fittings/valves. I can use my Robinair Venturi style vacuum pump, my Mityvac, my electric HVAC style vacuum pump, or even a Milton siphon-feed blow gun. I would only ever use the Mityvac in a “post-apocalyptic don’t waste the fuel scenario” lol manual pumping is for the birds. The downside of using the electric pump is the oil needs to be changed immediately afterward (which you are suppose to be doing after AC evacs anyway, according to the manufacturer, but who does?). The Venturi pump works fine, but I hate hearing a compressor run, so the electric pump is my go to. If I have more than $20 in the whole setup I’d be surprised, probably closer to $10. I used R12 style flare fittings so it would work with the HVAC pumps. The only other thing I had to buy was a ball valve. Had I been thinking ahead, I didn’t even need the ball valve. The setup works perfectly with an old set of manifold gauges. It’s just like charging an AC system and has the vacuum gauge and valves built right in!

35. Eric I use it all the time it is a time saver great Video.Use a 5 gallon pale with a fittlng at the bottom helps keep air out the line at start up

36. Could you use an ac evacuation pump with it? Cause a diyer might not have shop air.

37. What brand coolant do you use generally, Eric? I saw you used Zerex in one vid.

    Recommendation Eric?

38. Will this work with coolant in system or do I need to drain

39. I don’t think that it would buy a vehicle that would require that because if I cannot fix it in the driveway or a parking lot then I don’t want it to blow a leak in a radiator hose late at night or a Sunday afternoon because the shops are all closed so I will just find another hose and fix it right there and fill it with water and get home and make it right there with a new hose and coolant for it if it air locks inside the engine I will sell and get a older car

40. So you still have to get under the car to drain out the fluid first right?

41. do you have to make sure all coolant is out?

42. Maybe I don't understand this tool but when you open the valve to add the coolant, if the line is filled with air before the coolant starts flowing, aren't you putting air back into the system ??

43. Could you use it to pull the coolant, and pull a vacuum in the same step?🤔

44. I had that same air lift and it sucks. get the uvw550500 it is a wonderful tool. you will use it every time you have coolant loss on a repair.
