Did the job.

Does not fill entire cooling system like it should

It may seem like a lot of money for a simple tool, but If you value your time then you should get this if you ever want to do coolant flush. It will be a pain without it. I was doing a radiator replacement and coolant flush and this makes it so much easier! I was able to dilute the old coolant down to 1/512 of the original concentration in a few days without much effort. Then I pulled in new 100% concentrate. Running great so far. Not that if you have a powerful shop vacuum, make sure the vacuum does not go pass the yellow zone! Take a minute and read the manual.

Used first time on 2015 Jeep Cherokee with 3.2l V6 after replacing radiator. Worked flawlessly, took 15-20 minutes to change coolant. That includes waiting 10 minutes to see if vacuum decreases. Wouldn't have wanted to fill rad any other way.Tool appears to be well made, as well ad the case. Would buy again

This cooling system evap kit is simple to use and makes filling a closed system so much easier. Not only is it easy, it takes only a short amount of time. Would recommend to all.

Tested on a couple vehicle. Work as advertised. What more needs to be said?

satisfaction a 80% je l ai essayé disons qu' il est conçu pour un remplissage a 100% mais jai réussi a 80% le remplissage j ai eu pareille une poche d aire peut être vue que ces la premiere fois que j'utilise ce système j ai un manque d expérience pour le fonctionnement j ai amener le cadran sur le bord du jaune la prochaine fois je vais faire un remplissage a moytier puis refaire le vide car il manque un peut pouvoir pour un remplissage complet .

easy to use and well manufactured

Doesn't disappoint. Simply place tool in radiator neck. Tighten the expanding seal nut. Supply shop compressed air. Open valve to pull cooling system to vacuum. Close valve. Leave under vacuum a few minutes to leak test system. Then attach supply feed tube to gauge assembly, place end in coolant supply and open valve. Coolant is sucked into vehicle system. No worries of air pockets or damaging head gaskets. Fills system in one shot.

I use this kit to fill my Ford Edge 2007 and a Nissan Versa 2012, It work beautifully , No air on the system, verny set for a reasonable price, I highly recommend. I have a small pancake compressor , so you don't need a big compressor to use this kit.

Very nice, heavy, and well made for the price ($59.99 in my case). It fit snugly in my old Chevy truck's radiator filler neck using one of the 3 adapters, which are more like neoprene than just plain rubber. Would be nice if the scale was in "inHg" instead of or "bar" and "cmHg".

Works as advertised, it is quick and easy to set up. Pick the correct rubber sleeve for your car, install, add compressor air and instantly draws a vacuum. Good choice for the pesky tough to bleed cooling systems. I would buy again.

I found out about cooling system vacuum refiller kits while researching how to change the coolant in my car (which is notoriously difficult to change due to the tendency to get air bubbles and air locks upon a coolant change). Some people were reporting spending 8 to 10 hours doing ALL KINDS of crazy things to try and fix a hard to clear air bubble in my type of car. So, after a ton of research, I found out that these kits make changing your coolant literally a piece of cake and it only takes a couple minutes. This would be a huge advantage because I'm going to do a 'home flush' with distilled water, which means draining and refilling 3 or 4 times to dilute all the old coolant out (then refilling one last time with 100% strength new coolant).After researching, I found out that there is a leading brand of these vacuum coolant kits that costs approximately double what I paid for the OEMTOOLS 27066 kit. That brand gets great reviews, but I didn't want to spend well over $100 for my coolant flush. So, I picked the tool that seemed like the next best quality, and I was NOT disappointed. This thing worked GREAT! It literally took 30 seconds to place the cooling system under vacuum, and another 1 minute to fill a gallon and a half of distilled water back into the system. And NO air lock afterwards.Here's some things I learned:1) Pay attention to the reviews and closely look at the pictures of the kits you are considering. A number of cheap kits (not this one) look the same and get consistently bad reviews. The OEMTOOLS kit (and other branded differently but identical kits) get pretty good reviews. Also note that some of the kits do not have different expanding rubber bushings to exactly fit different sized radiator necks. They just have a tapered rubber 'cone' that you cram in there and hope it holds. I really prefer the custom fit of the OEMTOOLS style kits.2) When I first tried to use this kit, it did not work at all and would literally draw no vacuum despite running my air compressor for several minutes. I knew that my cooling system was solid. I knew that I had the tool well sealed in the radiator neck. Honestly, I thought I possibly had received a defective tool, or maybe my air compressor was not big enough to create the vacuum. I slept on it, and figured it out! My overflow hole is very low in the neck, and the tool was not able to seal that passageway. Simple fix was to remove the hose to the overflow tank and use a standard rubber vacuum hose cap to plug it. Once I did that, my small compressor created the required vacuum in literally less than 30 seconds.3) I have a very small pancake-style compressor. I think it is 2.7 CFM at 90 PSI. It had NO TROUBLE AT ALL pulling the required vacuum. I did not need a huge shop-size compressor.4) The other reviewer is right...the air compressor (male) fitting that comes on the kit is not the standard 1/4" quick-disconnect. It looks like it is bigger...maybe 3/8"? It definitely did not work and I had to temporarily rob one from another tool. FYI, in case you want to purchase one in advance.Hope this helps....this was a great tool and made this job super easy.
