I didn't think about the possibility of sucking air while cooling down, but should't the O ring avoid rom the to happen?

 

yes but the o-ring is also suppose to stop coolant from coming out and that's not working to well.

 

you should trust that I won't. I just cross my fingers and turn the key.

 

true....good point.
still bleeding every day.
When its cool in the mornings there is a ton of air coming out and then refilling...not much but even the noise is not going away...
I will keep trying...

 

Have you driven for more than a short while with temp control full hot to help get air out of the heater core?

......

 

sure tried that, it always helps but hasn't gone away yet.
I still need to replace one hose, and i think that for some reason it may be coming from there.
Planning on doing that Sat morning and posting a follow up.

 

Quit hacking with that stupid brass cap bolt and that fitting.
Just bypass it.
You don't need the bleed screw or the fitting.
Put in a brass pipe and clamp it tight.

To bleed it correctly --
1) Unclip the coolant bottle.

2) Take the cap off of the coolant bottle.

3) Fill the coolant bottle to the fill mark.

4) Run the engine at 1,800 RPM.

5) If coolant blows out the top like mad - stop. Shut it down. Replace head gaskets.

6) If coolant just goes down a bit - keep adding it.

7) run the engine like this for about 7 minutes.

Then take it from 1,800 RPM to idle..

With the engine idling - replace the cap on the coolant tank.

Put the tank in the clips again.

That's it.
Should be rid of the water fall sound.
Do not use the bleed screw.

Take that out and get a hammer, smash it and put it in the garbage can so it will not bother anyone else.

 

Note - you need to keep the coolant bottle UP as high as possible the whole time.
One way is wedge rags under it or 2X4 boards or something.

you could try to put a penny or a dime or a quarter into the throttle stop to keep the rpms up.

This is how I did it twice on my 2001.
