It is to your advantage to remove all of the air out of the coolant passages. That said you probably will never get absolutely ALL of the air out..ever. If you try real good though and do it well your truck won't overheat. Thats also why I said to keep the heat on for the next couple weeks because as you go up hills and have to downshift at times it will, in a way, do the burping for you, as long as you keep an eye on your levels (both in the radiator AND the reservoir). The way this could affect your performance is your engine's computer reads hey..this engine's running hot, lets go conservative here for a while to keep from blowing up. When the sensor's reading everythings ok then it'll let it run right.
I truly appreciate the links, I will first try cleaning the IAT and ECT, since that won't cost much. I already bought a thermostat, they're to cheap not to replace. As far as the tires go, they are brand new with the nipples still on them, so they will have to stay for awhile.
That's a good point. I didn't think that it running a little warmer than usual might throw the computers off. It has never reached the red or even past the "L" in "NORMAL" and since I burped it now it stays within the "ORMA" so I'm not worried about it overheating. I would just like to get it running as efficiently as a 4.0 can (even though efficient may not be the best word to describe a 4.0)
