Not sure what you're asking here. The system just is what it is. No different really than most cars. It usually takes me a few attempts to get it burped completely. can get most of it done, but after a good drive I can usually get a little more coolant in the next morning after things have cooled off again.

I will say there are some fancy systems that help bleed a system, but they aren't technically necessary to do so.

To "self burp" the 3.6l engines is simple. Run the engine up to operating temp (thermostat opening) then do a shut down and let the engine cool down, then repeat the process and adding coolant after each cool down. It's a little time consuming as you need to let the engine cool back down.
