What Year is it? If you did not hear any loud crunching/knocking it probably is a non-interference engine... Many claim my rodeo is a non-interference engine (95) I disagree with that because I heard loud crunching and I think my valves are bent. They say the rodeo became non-interference in 1998.
I bought my belts from different sources over the years, napa, pep boys, etc. My pep boys pump went over 100k without a problem. I felt better with the gates belt under the hood. The last belt was from NAPA and that failed, well, it slipped and I am not sure it was the belt that caused it.....
