So yes, this is an absolute time saver when working on the cooling system. You can fill and bleed the cooling system in less than 2 minutes. I like that about it. What I hate about it is that after evacuating the system you have to switch hoses and then fill the system with coolant. Maybe that sounds good to you. BUT before I bought this I was borrowing Vac Fill tools like this from co-workers. And all had installations with a hose. All you had to do was turn the valve. So I don't like it. Aside from one small inconvenience, this is an absolutely great tool. Make sure you have a big bucket to go with it. I bought a 5 gallon bucket from Home Depot for $3. Because if you run out of coolant before the system is full, you simply lose the purpose of using the tool. So get a big bucket and keep a few gallons in it. You will also need an air fitting as this kit does not come with one. Highly recommended to save time for fixed price technicians!
