| However I have seen techs do a 60k and move right to using the tool to pull vacuum on the system, only to find out that they don't have vacuum because it just pulls the fresh silicone out. The great thing about the tool is that it allows you to make sure there are no leaks in the system by allowing you to hold the vauum to make sure it doesn't leak back down.
