FSM says to bleed cooling system with rad cap on?
The common procedure is to do this with the radiator cap OFF so the air pockets in the system have a place to rise and exit from. Interesting the FSM repeatedly mentions to leave the cap on and then race the engine several times to 2500 RPM. Is there something special about Nissan cooling systems I'm missing?

Common sense says a closed system has to have an opening if you want something to get out. So the radiator cap has to be off. And that is exactly the way you do it.
Since the Nissan service manual was written on another planet in a galaxy far, far away, things get lost in the translation to Japanese and then English. Things are not always clear. Errors have been found. Keep using your common sense.

It's been awhile since I've read the FSM, but I remember bending a nail into a 'U' to hold the radiator cap open so the air would bleed out the reservoir tank.
Still I found it best to use a "no spill" funnel that attaches to the radiator, clamping the hose to the tank closed, and jacking the front end up.

They bleed super easy. It's a 2 min job.[/QUOTE]
This is the right way of doing it, the top off the radiator and the heat on full blast and rev it and let all the air out and fill if necessary. The bottom of the radiator is a bleeder screw valve that comes out all the way, this is the one that you use to empty all of the radiator out with.
