It not only you there were others on the same day that did the same thing, joined and started multiple conversation on different thread with the exact questions?
Honestly on any forum even none vehcle related there are some things just not done or accepted well.
but back on topic some appreciate your effort to direct your query in the best direction!

For the 2005, if you follow the hoses from the heater core, one of them leads to a split/restriction (made of plastic) near the throttle body.
This split directs core water to a metal tube sticking out of the throttle body, water goes through the throttle body and back to the other side of the restriction/split. The idea is to heat the throttle body with hot water...well, that pipe through the throttle body became plugged and reduced the amount water flowing through the core. It was crusty/corroded, but I did manage to unplug it; not an easy thing to do....but that solved the problem.
Given the age of your Tribute, if you can't get the tube cleared, you could just cut out the split and forget about running hot water to the throttle body. Prestone makes a flush/fill kit; in that kit is a plastic T with a cap...you could cut out the restriction and install that T in its place.
Checklist:
1. Forward and backward flush the core. If the system/core is old and crusty, Disconnect both hoses and use a shop vac to suck out the water. Then pour radiator cleaner into the core hoses, elevate them and let sit overnight or according to directions. Then forward/backward flush again.
2. Clean the pipe running through the through body and forward/back flush it. You could also pull the hoses off both sides and fill it with radiator cleaner too as described above.

The service recommended last should not be done except by at least a well seasoned DIY minimum!
Aside from posting one wrong thing you never do to an aged cooling system
NO reputable service shop would do that misdirected and incorrect method to solve a problem.
While I tend not to post to much in threads when there are DIY with good advise and experience I tend to get more adamant when I see a really bad service suggestion.

So this post states "service recommended last" but is not clear on what service is referred to.
The post states "Aside from posting one wrong thing you never do to an aged cooling system but it is not clear what "wrong thing" is referred to.
Same with "NO reputable service shop would do that misdirected and incorrect method to solve a problem." It is not clear what "misdirected and incorrect method" is being referred to.
In relation to those comments, the reason why or consequence of those "wrong things" or incorrect method is not provided.

linda2006….You have 5 posts and are a new member so understand your questions . However to be frank I don’t have the time to post every reason why some response and service advise and recommendations from some members and especially a DIY also a new member are not advised.
In the end it’s your choice .

good luck with your choice of service and service advise.
