How do I bleed the cooling system?
I think there may be air trapped in my cooling system since the heater seems to blow colder air when idling and only gets hot when the engine is revving. I tried searching the forums and apparently there's supposed to be a air relief screw near the rear passenger side of the engine bay, but my 2004 coupe doesn't seem to have the screw that everyone seems to be referring to. Instead it has what looks like an air valve that you see on tires with a green cap on it. Can somebody let me know what exactly I have to do to bleed/burp it?

For those that have changed their coolant, what's the brand/spec you used?
For the OP, you might try putting the front of the car on a set of ramps and open the radiator cap. Air should slowly work it's way out. Not sure if have to have the car idling or not. You might blow water out that way

Our cooling systems are notorious for being difficult to bleed. I recently used a funnel that I borrowed from rookie and it worked great.

I'm getting ready to change my coolant before the climate gets any hotter here.

You can squeeze the top or bottom radiator hose as you pour coolant in the radiator neck to get the air out. It's how I always did it on all the cars I owned including 2 4th gen Maximas.
You can also remove the lower radiator hose to drain the coolant out.
