Blazer cooling system

I need help with 3 problems on my Blazer's cooling system.

1. after I've been driving and then come to a stop, the coolant returns to the reservoir boiling and making a lot of noise

2. the fan does not keep running after I stop, it only runs when I drive

3. I have been having to add a lot of coolant/water every 2 or 3 days, but I can't find a leak anywhere

Year of Blazer & engine size would help. Do you see white smoke out the exhaust, is your oil milky looking? Could be a number of things. Need more info!

I live in Brazil, so the engine size is different than in the states. It's a 1996 Blazer, but it has the 2.2 4cyl engine that the standard S10s have in the states.

There is no white smoke coming out of the tail pipe, and the oil appears fine.

How is the radiator flow? Condition?

Condition of the belts and hoses?

When's the last time the cooling system has seen service?

the radiator flow is good, cooling system hasn't been serviced for about 2yrs, belts are all new, hoses are 3 yrs old

I'm probably going to have a mechanic's shop due the repair, I just wanted to be educated on what might be the problem. Mechanics here in Brazil get their mechanic's licenses out of cracker jack boxes and often don't have a clue.

The first thing I would do would be a coolant pressure test.
You may not always see a leak while driving.
It may be something as simple as a bad radiator cap.(wouldn't be the first time.)
The pressure tester can also be used to test cap.
