It’s not an interference engine, but it does appear to have a timing belt as opposed to a chain. I’d replace the belt now, rather than have it break at an inopportune moment. marta, the water pump is usually replaced at the same time because you have to remove it to get at the timing belt. The pump is not all that expensive.
