Mastercool 2cfm A/C vacuum pump,July 31, 2007
By Lang1234from Omaha
Pros: Quiet running electric motor, oil level sight glass, on/off switch,and easy to acess fill/ drain valves Cons: None - I have used it 3 times so far
"The first time I turned the switch on, I could not believe how quiet the motor ran. Other ones that I rented before from rentall places sounded as loud as a 747 jet. It pulled the vacuum on my 1996 Chevy Blazer down to 29 " after just 10 minutes, but I let it run another 20 minutes like the book says. Setting it all up to work was a snap - add the oil and double check the valve setting, and your good to go. Features that I like are the oil level sight glass that is up front and easy to see, the on/off switch on the electric motor housing, and the easy to access drain and oil fill valves. I have used it on two other cars and it is humming right along."
