UView550000 Airlift Cooling System Leak Checker and Airlock Purge Tool Kit, OEM Approved, Universal Connectors, Minimum 90 PSI/60 Bar, Used for Leak Detection, Purging Airlocks, A/C System Refill

This tool is an absolute "must have" for anyone who performs cooling system repairs on a routine basis. Instantly increased my productivity by reducing long drawn out air bleed procedures to mere minutes. There are many variations of this tool available in the marketplace. But the old adage holds true..."You get what you pay for". Now owning it for a few months, the solid metal construction of the Airlift shows no wear with everyday use, has proven to be a valued resource, and perform s flawlessly. I love tools that pay for themselves in less than a week! The only regret I have is that I didn't buy it years ago!PROS:Solid construction, ease of use, minimal moving parts, consistent performance, increased productivityCONS:Basic single compartment storage container is not padded. With all the loose parts free to move around, the vacuum gauge could potentially get damaged at some point.Adding my own protective foam inserts wasn't a big deal, but it would have been nice to see that keeping your tool investment free from damage was a higher priority.

Worked perfectly. Pulled vacuum very quickly, even with a small compressor. High quality tool, my only concern is the case seems a little flimsy.

This is a really nice, high-quality vacuum coolant filler. Not cheap, but you pay for quality of which I have no doubt this will last for many years. Its construction is all heavy-duty metal, brass I believe, and all the valves are solid, high-quality pieces as well. I've seen some made of plastic or cheap metal which would probably be fine for occasional home DIY use but not for repeated, professional use.There are a few rubber adapters included but I've found the cone adapter is all you really need. I have used some of the other adapters but that usually requires pinching off the overflow tube which isn't a big deal but it is an additional step.Filling is a very satisfying process! The radiator hoses get vacuumed flat and the coolant just flies into the cooling system. Very cool. Once the needle reaches zero, you're done. Quick and easy. You may have to top up the coolant a bit. Also, if the vacuum gauge moves (before filling with coolant), then you have a possible leak somewhere. It's an excellent system and product.

This product worked great for my application! My truck has a rear mounted radiator which is a PITA to purge air out of the system. The included instructions were great and the packaging/tool are of quality.This tool made changing out the water pump easy! My system holds 5 gallons of coolant and was filled in under 5 minutes. Not only does this fill your system, making sure there are no air pockets, but it’s also verifying your systems sealed (if it holds a vacuum).

This tool is a must have. I bought this specifically for my ls engine after researching about changing the coolant and finding out air pockets can be common. Not wanting to risk overheating I thought I would try it.Super easy to hook up, draws down all of the air in the system in less than a minute with a small homeowner air compressor. Worst case you could always close the valve and let the compressor cycle before drawing more vacuum if your compressor is really small.Switch to the fill attachment after you have sucked some antifreeze to fill the tube, connect it and open the valve on the head and then the tube and it will fill the system on both sides of the thermostat in less than a minute. After the gauge reads zero, remove the gauge heat from the overflow, replace the cap and you’re done.No air in the system. This tool is worth the cost just for the time savings alone, not to mention no mess, and no risk of an air pocket by your thermostat possibly causing overheating and possible engine damage.The tool is very well made with brass ball valves and a nice gauge.If you’re reading these reviews, just buy it.

So yes this is an absolute time saver when doing cooling system work. You can fill and bleed the cooling system in under 2 minutes. So that's what I love about this. What I hate about it, is that you have to switch hoses after you put the vacuum on the system, to then, fill the system with coolant. Maybe that sounds fine to you. BUT, before I bought this I have been borrowing co-workers' Vac Fill tools similar to this. And they all had single hose setups. All you had to do was turn a valve. So I don't like that about this one.Other than the slight inconvenience, this is an absolute great tool. Make sure you have a big bucket to go with this. I got a 5 gal bucket from Home Depot for $3. Because, if you run out of coolant before the system is full, you just defeated the purpose of using the tool. So get a big bucket and keep several gallons in it.You will also need an air fitting because this set does not come with one.Highly recommended time saver for flat rate techs!
