If I wasn't in sort of a bind I wouldn't consider it. There is an illness in the family, and I need to pick up some stuff in that town (WA). I just replaced my front rotors and brakes, changed auto tranny fluid and filter, putting in a new O2 sensor and TPS today or tomorrow. Would be nice to put off the radiator thing a bit longer. I recently drove it about 400 miles over a week or so, and while the coolant did get a bit low, it was not dangerously so, so it seems that the leak is very tiny. My welder neighbor, a really good mechanic, thinks that the Bars approach would be good enough. But I am torn between the two schools of thought illustrated above.
