The Chiltons mentions it and the GM Service Manual mentions is specifically for the 2.4L but I can't seem to find it and there's no useful diagram.
I've just done a coolant flush. Opened the petcock on the radiator and drained it. Filled it with water and ran it until it got hot, then drained it again.
Now, on filling it, I only got a about 5 quarts into it and the manuals seem to think I should get double that. I've let the car run and it went down a little but not much. I'm worried that because I can't find the bleed valve, I'm going to have air bubbles in the head and blow something.
Can anyone give me some better instructions on finding this thing? Or tell me why I didn't get 10 quarts into it?
I just drive the car for a mile or so, then top off the coolant.
And I don't know where the bleed valve is on the 2.4, but that picture looks like an older model 2.2L
you should be able to squeeze the upper radiator hose several times and get the bubbles to circulate to the resevoir, or pop while in the system. I usually do that and keep an eye on the level for a few days.

if u just drain the coolant out of the pe cock, u still have about 2-3 gallons in the motor. if u wanna drain it all, u have to pull the radiator tube off, on the back of the motor where the thermostat goes. and as far as i've ever seen on my 2.4, there is no bleeder vavle, the 2.2's were the only ones to have it
Theres a little coolant line thats at the back of the motor above the header.....I usually just take the hose off the hard metal line.....and wait until coolant starts comin out there.......works for me everytime

As I said, there's mention of a bleeder, even in the GM service manual, referring specifically to the 2.4L engine. I just can't figure out where it might be.
Hopefully all is well. I'm gonna drain and add fluid again in a week or two, just to get as much of the old out as possible.
When i changed my cams i had to drain the coolant, was told to leave the cap off while running, tends to help with bubbles, same with squeezing the hose, definitly agree though, think i've added 8 qts total since the drain, and had a low coolant light the other day (small top off fixed the deal), i'd say just keep an eye on it. If the temperature gets high in the city, then you have an air pocket, (what happened to me).
I take the same rubber hose off the metal line, and squeeze the upper rad hose until the coolant starts pumping out of that line.
Never had any issues, and I've done it 5 times now.
i have never seen a bleeder screw on a 2.4L.......just fill with coolant and run it.....that line in the back is a bleeder hose, you could say..... eventually the air will bleed out..
THERE IS NO BLEEDER SCREW ON A 2.4l TWIN CAM. IT HAS BEEN KNOWN THAT CHLTON'S AND HAYNES MANUALS HAVE MISSPRINTS, THIS IS ONE OF THEM

Right... but it's specifically mentioned in the GM service manual. The section refers specifically to the 2.4L.
I feel better now though. Thanks guys! If all your engines haven't cooked themselves yet... then I should be fine as well.
