Timing Belt

If you're certain you have a timing belt (I thought the 2.5 was a 4 cylinder and it may have a timing chain), it may be about time. A while back, a lot of manufacturers recommended 60k. Now the belts can go a while longer (my 98 Pathfinder says to do it about ever 90k). If you do have a belt, I'd probably start planning for it. It'll be an involving project and you'll probably need another car for one or two days (and this is if you have a shop do it). But I'd say you probably have at least 10k to go safely. And once you get the front of the motor taken off, you may just want to have them change the water pump (right in the same area, and the motor would have to be taken apart to do that too). But you should still have a little time left on that belt.

It has a timing chain, you shouldn't ever have to replace it.

It has a chain and a chain is good for the life of the car generally. You don't have to do anything if it is running fine and there is no noise coming from your engine.

i just bought a nissan altima 2016 and the dealer said the timing chain never has to be replaced, which is the reason why i'm here looking it up.

I'm getting ready to pull the trigger on a 2017 Altima. A HUGE factor in picking it instead of another Mopar is because it has a timing chain and NOT a belt. Love these cars. Quick, economical and fun to drive.

I have a 2008 Altima. I don't know if the belt has been changed. it has 186 miles on it . what do i do?

If your car has around 60-100k miles it’s good to change the timing “belt” the timing chain should not have to be changed. And this is on any car typically, you should really look at your car engine manual to be assertive of when to really change it.

I know a guy who drove his altima very hard, ended up sounding like a diesel, had to replace the timing chain, drive sensibly, timing chain should last the life of the car, if it sounds like a diesel, beware
