Happy New Year to Everyone, Prestone also makes a coolant recovery system that you use with the flushing tee. The tee goes in on the heater hose and this plastic hose goes over the end where the pressure cap goes. When the garden hose is attached to the tee and turned on, the old coolant is pushed out into the clear plastic hose and into a large clear plastic cube. You then take that to a recycle center. I have picked up two of these as close outs at stores, but have not used it yet. I believe that the cube holds about 5 gallons of liquid. It will be months before I try to use this, so if anybody has used this system, let us know how it went. Thanks, Gary Masie
