I have a 2004 Buick Century (V6 3.1L autom. transm.), and the owner’s manual speaks of it having an “Engine Accessory Drive Belt,” but does NOT mention anything about a “timing belt” or “timing chain.” So does this mean that the car has an “Engine Accessory Drive Belt” INSTEAD of a timing belt/chain?
Also, the manual does not mention the car as having a “fuel filter,” but I’ve been told that it does have one. How often, if ever, does the fuel filter need replacing?
