Just buy one already
First off, I was in search of a kit that would fit my truck and I had been to 2 different stores to which nothing they included fit or produced a proper seal. Then I found Four Uncles and was pleased to find that it fits my 2018 F-150 (3.5 v6). I was able to run a small test (will have to do a more in depth test later) but my initial impressions are that this little kit is well documented (on amazon and in the manual), very diverse with the adapters (and it even includes more than I'll ever need to use will the refill kit included), the quality of the adapters feels slightly higher than mid-level but also sorta cheaper, however I'm fairly confident that they won't break that easily especially if you don't abuse them. The pump is a pleasure to use with no issues found yet, in fact I love how the pressure release button doesn't feel stiff and it seems to work well. Remember you get a lot with this kit and it's priced just right. If you are a do it yourselfer you need to try this kit. I bought it with the intention of keeping it even if it didn't fit because it was priced very well but I was also amazed at how nice this kit was. It feels like Four Uncles really care about their product so give them a shot if your on the fence. Thank you Four Uncles, I am happy I can finally stop chasing down the right tools!

Another great tool from Four Uncles!
Had tried two competitors and returned both units because they did not work as advertised. Then realized Four Uncles offered this product…it worked flawlessly!! I wish I had come across this kit first. From the hardshell case to all of the different components included, this is a great value for the money, and really demonstrates the quality of the product. Simple to use and easy to follow instructions included….would highly recommend!!

What you need for the new century!
I've used this unit on several vehicles now and have found that it is a necessity for the newer vehicles. I would rate is as good for a weekender rather than a high production shop with multiple users. I loved my old Stant but there are so many variations now, a kit like this is a necessity.

Vacuum fill is okay. Hand pump leaks right out of the box
The vacuum fill part works well although it’s very noisy and uses a size and thread pitch for the compressed air inlet that makes it impossible to connect to shop air. Also, the pump leaks at the hose fitting where the adaptors are meant to attach and although it supposed to come with a one year warranty, customer support doesn’t respond at all. //// UPDATE //// Customer service took a few days but did respond and instead of sending one part to fix my issues they sent a whole new kit! Very pleased now! Would give 5 stars but noisy vacuum filler and odd thread pitch are the only draw backs.

It save me $2000 in mechanic shop labor repair
I recently used the Radiator Coolant Pressure Tester & Vacuum Refill Kit, 28-Piece Universal Cooling, and I couldn’t be happier with the results. By using this tool, I saved a whopping $200 in mechanic labor costs! The kit was incredibly easy to use, even for someone like me who isn’t a professional mechanic. The instructions were clear and straightforward, making the process of testing and refilling my car's coolant system simple and stress-free. What impressed me most was the comprehensive nature of the kit. It included everything I needed to get the job done, and all the components were of high quality. The pressure tester helped me identify a small leak that I wouldn't have noticed otherwise, and the vacuum refill tool made it easy to refill the coolant without any air bubbles. Overall, this tool has paid for itself in savings and convenience. If you're looking to take care of your car's cooling system without a trip to the mechanic, I highly recommend the Radiator Coolant Pressure Tester & Vacuum Refill Kit. It’s a fantastic investment that has already saved me $2000!

The quality of this tool is unbelievable.
This product comes with EVERYTHING you could ever need to test any automotive cooling system. AND I MEAN EVERY AUTOMOBILE! You can even test the radiator cap. Not only test; the kit includes all necessary components to correctly refill the coolant system without the introduction of air. That feature alone should be a separate tool, but it's in there! This test kit should sell for 4 times the price. I'm certainly glad that I got one now. This is a gold mine! The quality is obvious, the user manual is very detailed. Buy one for yourself and don't let anyone use it! Everything is top shelf with this. Trust me. I've been throwing wrenches for 55 years. It's so beautiful, I don't want to close the lid. Going to take it in the house and just look at it for a few days, LoL. Thank you Four Uncles - you did good 👍.

essential flows on a non-working product
a long time passed until I actually try to use it for vacuum bleeding and two things became very apparent right from the start. instead of creating a vacuum, it actually put pressure in the cooling system, initially i thought operator mistake, but nope, it didn't work. furthermore, when checking with your finger, the vacuum is not that strong at all. second important issue is that it doesn't have an on/off button to manage the airflow; hose on and its running -- this compared to its competitor products. lets forget the noise levels for a moment, but only by removing the hose one can check or test what's actually going on. the hand pump was also leaking and not holding pressure; the reason i can say that is because when the "vacuum system" put pressure in the cooling system, pressure stayed and didn't escape vs the hand pump. because such a long time has passed between purchase and actual first use I'm not able to return it! irrespective, fortunately I previously bought another system of different design, rubber seal and flange put inside expansion tank -- it all worked! -- update: i have to acknowledge that the company reached out to me and apologized for the poor quality and performance, wanted to work to improve product and issued a refund. something not very common nowadays and a positive experience dealing with a chinese business.
