Just a heads up...a few years back I installed one of those Prestone inline tees that goes into the heater hose. You know the one...it lets you hook up a garden hose to it to flush the coolant system. Long story short, out of the blue it split in two on the freeway doing 80 and needless to say temp shot up quick, and nearly all the coolant left the building fast. Fortunately I stopped quick too, and had to bybass the tee. I carry a couple of gallons of water in my truck just in case, and it got me home without further incident. Lesson learned...tee is temporary...comes out after flush.
