I don't understand the coolant bleeder/tank system

[mikesz]

I have a 99. I replaced coolant when I replaced the first water pump, thermostat, front engine mount. I purchased a UVIEW device and gave up trying to use it and sold it. I thought it was a PITA. I did what others have done on this forum. I jacked up the rear of the car, filled up the system, open the bleeder valve and drove around my neighborhood. Worked fine for me! I did it again when I added an "S" center radiator and again never had any problems. Just speaking from my experience.

In other words, what Meir said!
