UView550500 Airlift II Economy Cooling System Refiller

Works just fine

if your a mechanic this is a must when refilling cooling systems. most later model vehicles require a complicated bleeding procedure. with this all you do is put this over the hole for the radiator cap then hookup your shop air and it vacuums the entire cooling system and then fills it back up with no other special bleeding procedures. its super easy to use and it pays for itself in no time. this is our second one, our first one crapped out after a few hundred uses here at our shop. you just cant beat this for the price.

I used it yesterday to fill up the cooling system of a 1990 525i with the M20 engine. Pretty soon after pressing the button, the hoses collapsed as expected. However, I was not able to bring the vacuum down to -25 inches as instructed. I am guessing that my 50 foot 1/4 inch hose is the culprit. I increased the line pressure to 100 PSI and the vacuum improved a bit. Since the tool takes 90 PSI maximum, I decided to continue with 90 PSI per instructions. The vacuum hose sucked almost two gallons of coolant and distilled water in no time at all. It is a good idea to keep an eye on the level, so the tool doesn't suck in air. Being one of BMW's finickiest engines to fill up with coolant, I still had to open the reservoir and thermostat bleed screw to let out some remaining bubbles of air. Overall, It worked very well and I am happy with the purchase. I wish the form factor of the tool was more compact, because it takes a lot of space in my tool box.

This tool is awesome. Perfect for refilling the cooling system after a water pump, hose, or thermostate change, or for flushing your coolant system. You attach it to a strong compressor (really need about 120# of pressure for this tool to create the proper vacuum level), place it in your overflow reservoir and create a vacuum on the cooling system. You then turn on the intake valve and refill your entire cooling system in minutes from a bucket of pre-mix with absolutely no air in the system. Not only a time saver, but a must when working with modern engines where trapped air in the system will cause overheating and damage the engine. This company makes two versions of this tool...this model which is made of plastic and a professional model made of brass. If I were using it on a daily basis, I would probably go with the more expensive brass model, but both work the same, and this lower priced plastic model is perfect for home mechanics who will only use it occasionally.

The vacuum works well, but when you fill the needle stays stuck, so you don’t know if it’s done filling. Other then that, no air pockets in any of the cooling system jobs I’ve done. I also would prefer a ball valve, so you don’t have to hold the button the whole time when vacuuming.

Considering a shop charges up to $90 for coolant system flush and fill, it made sense to buy this tool. There are 13 quarts of coolant in my truck between the engine block and radiator. The coolant was pretty old and I needed to change it all. I drained the radiator, re-filled with distilled water in about 3 minutes with this tool, ran the motor (heater on) until the T-stat opened for about 15 minutes. Let the motor cool down, then drained and re-filled the radiator with water, run motor, etc. 4 times until the coolant was clear water. After the final radiator drain, I re-filled with 100% coolant to mix with the water in the engine block for a 50-50 mix.The tool works great in preventing air pockets in the system and I also found a few flat band hose clamps that leaked when the tool pulled a vacuum on the system.There were other similar tools for more money, but this one worked fine for me.

Audi owners can verify how difficult it is to purge the cooling system of air after a coolant flush or timing belt job. It can be a royal pain and cause a loss of heat in the cabin due to pockets of air in the cooling system. This little miracle worker completely eliminates any worries about getting air in the system, and it's easy to use.This is one of the best tools that I've ever purchased for my A4 and S4. It's worth its weight in gold!

i purchased this same re-filler about 8 years ago from my local supplier...when it went bad i ordered the exact same model from your company....the first one right out of the box would not hold vacuum...i returned it for a replacement which was expedited.....it worked great for about 4 uses then that one would not hold vacuum either...so i decided to purchase from a local supplier for a higher price and so far that one is working fine
