Nope! I know when I changed my thermostat last year I did it the way CIVICSIRACER mentioned. After a week or so my car would still over heat only every once in a while. I had to bleed it using the valve several times before it permanently stopped. I don't see why they'd have the the bleeder valve if the resevoir performed the same purpose.
It's my first day.

What's this bleed valve look like? Is that by the valve cover?

Thats the best I can explain it. Just loosen it until you see bubbles coming out. Tighten it back up after no more bubbles are coming from the tip. Should be a small steady stream of coolant.

The pressure cap only bleeds off excess pressure, it doesn't necessarily allow air to escape. The bleed valve will be located at the highest point of the colling system - an air bubble will tend to settle there when you shut the car off (of course let it cool before opening).

I DID read the thread - you asked why the reservoir doesn't automatically bleed off air bubbles, I explained why it does not. It's not my fault you don't understand how the cooling system works.

thats not what you explained. Youre talking about the pressure cap, the cap on the resevoir is not pressurized.

The overflow cap on the RADIATOR is pressurized (spring-loaded valve), this bleeds off excess coolant through the overflow tube to the reservoir when pressure gets too high (it releases at 12-14 PSI on most cars). It will not selectively let air out, unless the air bubble just happens to be sitting next to the pressure cap when pressure gets high. This is unlikely, since the air bubble will circulate with the coolant as long as the water pump is running. The bubble will rise to the highest point when the car is off, which is where the coolant burp valve should be located.
