Been bleeding for 25 mins and fluid is still bubbly!
Lessons learned: leave motor off, use small clear pipe lol, pinch return house...I'll add a pic for any other newbs attempting this like myself lol
Thanks Shardul and Alvin!

Coolant bleeding help
I am trying to bleed air out of the coolant system and I cannot seem to get it to work. I have the hose after the nipple clamped off and the heat on 100%. however, no coolant or air is escaping... Help??

What is your line doing to ext reservoir? Or did you mean the coolant res?
Is the pipe(hose) too large? My coolant wouldn't bleed before because the hose was too big in ID and length. So I got a clear one from home depot that just fits INSIDE the bleed nozzle!
If still nothing try squeezing more on the pinch point on the return.
Leave motor off. Run pump. Report back.

I tried yesterday the clamping method and water came out with pretty decent force. Heck, I could shoot it at the walls of my driveway if I wanted to. Kinda makes me wonder if you guys have pump problems.

Tony, what size hose is that? and I discovered my old pump IS working, so i looked at all the fuses and found a lbown 15 amp, but temps are still up there after I replaced it.. and is there any way to jump the pump with 12 volts without jacking up the car and removing the skid plate?

1/4" (OD) x .170" (ID) x20 ft
Cut it down to the smallest length possible to the res. tank.
Gotta jack the car up unfortunately to get to the pump. I took power directly from the rear battery with a long wire. You can use a 12V DRILL battery as well.
