I just wanted to know if anyone had any idea how long/labor intensive the timing belt replacement on the '04 Sentra takes? Anything I should be aware of or special procedures before taking this job on? Also, what mileage interval is this usually performed at? Thank you.

i thought they all had chains?

I honestly don't know. I have been a domestic engine guy and the '04 Sentra is my finance's. If it has a chain, what is the service mileage for it then? Procedure? Time involved? If it has a chain, I would imagine it can go at least 100K miles right? Anyway, any help or suggestion would be appreciated. Thanks.

I should probably mention that it is the 1.8S as well, should that make a difference or help in determining what it has.

im pretty sure its a timing chain...hold on lemme check for sure.

yep chain. alldata says 5.9 hours for the job. thats average for a mechanic. so if your not a mechanic figure a bit more.

but you dont need to. as far as i can tell nissan has no interval. meaning the chain lasts as long as the car. but im sure you could call a dealer and get that confirmed.

Nah, thanks. I just thought it had a belt and usually they would need changing around 75K or so. I just happened to notice her car had 90K when I was doing her oil change this weekend so thought I would ask what was involved. But if it has a chain I would have figured at least 150K before I would have to worry about it on this car. Thanks for the info. though.

120k id at least check it out, if anything the tensioner might need replacing, or the guides
