How often change the timing of the Nissan Altima 2.5 from 2009?
chain...be safe about 100 thousand miles ..engine will retard and power will drop off as it stretches.but Nissan has used timing chains on the 4-cylinder and 6-cyliner Altimas since 2002. They are designed to last the life of the engine but, unfortunately, sometimes they don't. just like anything else.The good news is that they are not prone to just snap like a belt and they normally give you plenty of warning before failing as they will start making progressively more noise.
