I have a 1990 Lexus es250 with 149 k on it, and I am the second owner. I don't know when the previous belt was replaced. At what interval should I replace my belt? Also, I was told i have a non-interference engine. Can someone confirm this?

 

Im pretty sure these early engines required a timing belt every 60k miles. And to my knowledge, it is an non-interference engine, but i will try to check into that and post back.
