does my car have a timing belt or timing chain

What is your car??

1996 olds cutlass 4 cylinger

Chain

Cutlass supreme? You sure that it's a four cylinder? I am only finding a 3.1 or 3.4 L v 6 in any of these cars. And the 3.4L is a belt and it's also an interference engine.

I ran it threw autozone on a 4 cyl.It showed as chain,but that said dandy is right all so,depend,s on year and model,ciera or cutlass.

Agreed.
