Does a 2003 Buick century have a timing belt?

Welcome to the site. First, is it a 2003 or 2004? It says both in the title/question.– kyle_engineerAug 21, 2017 at 21:58

This car has a timing chain. No timing belt worries, then. Also, no chain worries according to the link. Some cars with timing chains have a chain system that isn't good for the entire life of the car, but apparently your car doesn't have such a poor timing chain system.

The chain on those 3.4 and 3.8 engines will more than likely outlast the life of the car.– BenAug 21, 2017 at 23:06

FWIW wikipedia says its a 3.1L. In case others come across this, where you need to worry about GM timing chains is on overhead cam motors (which he sure doesn't have in the Century)– agentpAug 22, 2017 at 13:29
