Review on Robinair 75700 CoolTech Automotive Coolant Exchange Machine by Shane Black

I'm not a professional, just a "car guy" with too many cars in the garage! This is a luxury item for me, but I'm sure glad I bought it. The build quality is excellent, the directions are simple, and it comes with all sorts of connectors and adapters. The fluid levels of the tanks on the machine are all clearly visible, as are the quantity markings. So it's very easy to tell how much coolant was removed and how much was put back in. Draining, refilling, and bleeding the system are all very easy. No more crawling under the car, fighting petcock valves, dealing with drain pans, etc -- all of that is eliminated!1 feature I especially like is that this machine is capable of completely removing all the antifreeze in a system, so u know that none of the old grungy coolant will be mixed with the fresh new coolant.I've only done 4 cars so far, and I can already do the entire job in about 10 minutes without even getting dirty! And I expect to get more a lot use out of it to do family and friends' cars.
