Recommend radiator flush??

What is your question?

3.4 L replaced thermostat after it suddenly stopped blowing hot air. I believe I got all air out of system. Still not working correctly. No obvious leaks etc. Would changing belt do any good?

Don't think replacing the belt would help. Try bleeding the system of air and adding engine coolant.

Ok..what is best way to do it? I have service manual it just isn't very clear on doing it step by step. Not sure if cooling fans have been turning on either. Manual mentioned something about marks on tensioner, that indicate the belt being worn out. Thanks for the help
