Buen material,herramienta muy util..te evita la purga del sistema..gracias!!

After reading the reviews on various tools of this sort and an immediate need for a this kind of tool I settled on this brand. I decided to go mid range on the price and this tool had high ratings. Not using a tool like this before to add coolant to a cooling system I was a bit apprehensive as to how it would work.The application I needed it for was on a class A motor home that would not accept the fluids by gravity flow. I knew how much fluid I had drained from the system but could not inject the same amount by filling the recovery bottle, as this was the only means to get fluid into the system. The heater core being the highest component in the system seemed to create the problem. Upon a "How to" search I learned about the process of using the vacuum method to charge the system.How did it work? --- The tool is well built and the adaptors that came with the tool served me well. I had to mount the tool on the recovery bottle and since I was changing all the hoses I put a vacuum test on the system to see how the tool worked. It pulled a heavy vacuum and held it for hours before I changed hoses. I did a radiator flush and had to add water to the system and all went as expected. After changing all the hoses I put a vacuum on the system to see if all the fittings were tight and it held a vacuum for over 24 hours. This was an indicator the tool sealed well to the recovery bottle and that there would not be any leaks in the new hose joints. The screen on the charging hose was not an issue for me as the fluids were sucked into the system in short order. This was about 4 1/2 gallons in a 5 gal. bucket. There was still a vacuum in the system when the system was full. Because the gauge is on top of the unit and my recovery bottle is elevated I had to use a mirror to read the dial which was not a problem.i have a 5 horse compressor in my shop and air pressure set at 125 psi. Using 100 ft of air hose to the RV it pulled the vacuum down in about 2 min. This tool uses two hoses. One for the vacuum and one for the fluid transfer. I found no problem with the interchange of the hoses and the ball valves worked well. I did elevate the 5 gal bucket with the antifreeze to the proximity of the recovery bottle to help the transfer.The directions were plain enough to get the job done and after playing with the tool a bit it all fell into place. Mission accomplished!I would recommend this tool for the quality and ease of use. Unless you break this unit it should last a long time. I am glad I bought this one.

It is a good product for system leak check and coolant filling...checked in Heavy duty vehicle truck ...

I seldom write reviews but for this tool I'm happy to. Used it to purge an air lock and flush the cooling system of a 2001 VW Passat. Worked extremely well. Evacuated the air in less than a minute, then sucked in fresh coolant within the next couple of minutes. I'd tried to eliminate the heater core air lock a few times before using other bleeding techniques. None worked. This worked first try. Also, tool is sturdy and well built.
