Cooling System / Timing Belt Questions - 1995 Honda Passport

I just recently flushed my cooling system in conjunction with other work being performed on my 1995 Honda Passport. After flushing the system, I added a Radiator Anti-Rust bottle to my system. It's white in color. The
coolant is green in color.
Originally, and before I added the Anti-Rust, the car would overheat after about 2 minutes of running. This ended up being a mis-installation of the thermostat and, therefore, the system was re-drained, the thermostat installed correctly, and now the overheating problem has disappeared.
However, it seems that the coolant in the system isn't flowing through the radiator.
Question: When the car is running and the radiator cap is removed, shouldn't the coolant in the radiator be flowing THROUGH the radiator rather than remaining still?
The color of the fluid in the radiator is still a milky white. There was enough fluid in the rest of the cooling system to offset the white color of the Anti-Rust and all fluid should be green, or at least a very light green. The fluid is white.
It would seem that the fluid beyond the radiator is not moving through the system. Yet the car is not overheating.
Does this cooling system have an air pocket in it which is preventing flow along the system lines? If so, how does one remove the air or, in other words, "burp" the system on this vehicle?
Forgive me being long-winded, but my wife just brought up another idea:
Also re-did the timing belt during the work process. It now turns out my idea of re-using the hydraulic tensioner for the timing belt was a bad idea. When I first start up my car in the mornings or at various parts of the day where the car has been sitting, there is a very nasty squealing sound which is heard until the car idles up. I believe this to be the timing belt being either too tight or too loose because of the faulty tensioner unit (a new one is on order).
At some times in the mornings, the squealing is so bad that the car shuts itself off. I would tend to think the car is shutting off because the tensioner is causing the belt to be too tight. Any thoughts?
On the other hand, is the tensioner too loose and, therefore, the water pump isn't functioning properly because of this? Yet, the car is not overheating. Or is it overheating, just not at the point where a temperature sensor picks up this fact?
Final question, it seems at some point during my work the idler pulley was discovered to be pretty loose. I do not remember loosening it. My mechanic friend re-tightened the bolt to it. Did THIS get tightended too tightly and is this causing the car to squeal and shut off (I doubt this)? What is the correct torque for the idler pulley on this vehicle?
After reaching a good idle, the car runs great. Been driving it for about 250 miles post work being done. The squeal's got to go, though. It's pretty annoying.
Thanks for any advice/input.

would have to sit at idle a quite some time to get it hot enough and if its cold outside it may never open. Take the cap off and hold the throttle partly open for a few minutes.

only when the engine is hot enough. No reason for the water to flow through the radiator if the water in the engine block isn't hot.

would overheat....period!!

3 strikes and you're out. You messed up 3 out of 3 jobs. Take it to a mechanic. I may end up costing you dearly.
Try draining the coolant and flushing the sytem with water alone and then putting in new coolant.

No way!!! I'm way ahead of the mechanic game at this point. Besides, where I live I wouldn't trust ANY of the mechanics in town with my car. This is just a simple problem which needs a little more attention than it got in the first go-around. The car runs great, except for the squeal when it starts, which goes away. Gas mileage is way up already. Power is increased at least by half of what it was before. Installed a new air intake which has produced this result as well as the work I did in the heads themselves.
The work is not easy, but very straightforward. It doesn't take a mechanic to get it done, either. But a friend who is one helps. :)
I'm still on base.

Are you sure the timing belt is the one making the noise? Maybe an accessory belt is not tight enough and it's slipping causing the squeal.

yes you are supposed to "burp" the coolant. on the couple hondas i've worked on theirs a bleeder screw near the throttle body. crack it open and then fill till it starts squirting out.
also the squeal is probably from the other belts that loosen when new. their is a "new" tension and a "used" tension when installing the accessorie belts.
even if ur timing belt was too tight/ too loose i'm sure as heck it would be spinning the water pump.
no idea on the car shutting off. any engine codes?
good luck,
jay
