99 Corolla, timing belt or chain??

I purchased a used automatic 99 Corolla about three years ago with
about 66,000 miles on it. My dad is very concerned that I get the
timing belt changed, because we are not aware of whether this was done
before I got the car. However, I have heard lately that my car may
have a chain instead of a belt. I do not have a manual for the car and
am having difficulty disovering what the actual case is: belt or chain.
Could someone answer this question for me definitively? Also, if it
has a chain, is there any maintenance associated with it that I should
be aware of?
Thanks!

Your engine does have a chain, and there isn't any real maintenance to be
done. Your can expect a service life well over 100k miles
