Okay so I had an issue, car was getting hot on short freeway drives.
So I bled the coolant system. Air came out.
Drove down the freeway, still getting hot (right under the second bar by the H)
Bled it some more, more air.
Went to the store, bought water wetter, poured it in. Poured in distilled water,
Still getting hot.
Bled some more, more air, twisted it a little too much and I had a coolant geyser.
Filled up the reservoir. went to the Max on the res, no big deal.
Drove the car, car runs great.
No over heating, hot air works just dandy, at idle/running, no funny idle.
Went to bleed again to see if there was anything left, no coolant, no air.

Res level is still at max, radiator can't except anymore fluid.

I am assuming the thermostat works because I the lower radiator hose gets warm/hot

So long story short, no coolant, no air from bleed valve. I am assuming this isn't good. What is going on?

Similar issue, no resolution. Help me out here fellas.

Edit. Just remove the bleed valve cap, added distilled water to replace any air that is right there. Will heat car up tomorrow and take for a test drive to see if this fixes this issue

 

I wasn't having the overheating issue, but I wasn't able to get coolant to the bleeder screw when I first was bleeding my radiator. I squeezed the hose to get it to fill up to that point then tightened it down, ran the car to bleed, and filled the radiator.

It's covered in this guide also:

It also goes over the bleeding air process which takes longer than how I usually bleed but it works, and fixed my issue I had. (Heat wasn't blowing hot at idle, and could hear water in the dash)

Report back with if your edit worked.
