Just bought an 01 xterra with 77,ooo . Manual says change the timing belt at 105k BUT should I be concerned over the age of the belt ?????
Thanks in advance for your help.

Yea, it could be a problem. I wanna say it's 105k or 5 years but I need to check that.

BTW, welcome to CX! Go post up an intro in the new member section! :)

Ouch! That is bad, bad, bad...........................


And, a belt missing the cogs like that on an interference fit engine like the Xterra will get you valves like this:

My Xterra has 72k miles on it, and it was put into service in March 2004 (when the original owner bought it). So I plan to get my timing belt and water pump job done this coming Spring or Summer; just to be on the safe side. I'm not too positive about the "5 year" thing, but I know it's 105,000 miles or before that it should be changed along with the water pump. So I'm just going to do it this Spring/Summer regardless of the mileage. Might as well right? It can't hurt anything, and it helps me avoid an unexpected valve workover like the one pictured above.

Timing belt is 105K (spec from nissan) and Gates says anything over 7 yrs and they should be replaced not matter what the milage.
Thanks Ian...that's the answer I was looking for. I still think I'm going to do it maybe by next winter (Dec-Jan '09)...just to get it out of the way...hell, I've already changed out so much crap on this truck last week...but it was all preventative maintenance stuff (with the exception of the leaking power steering hoses...those had to be done). Might as well make this my project for next winter's maintenance items, and do it during the vacation time I get for Xmas.

Knock Sensor - A lot of first gen Xs have that code active - mine included. It will not turn the check engine light and from what I've read doesn't have any ill effect unless you're supercharged. Not exactly a cheap part but it looks like a huge pain to change out.

HUGE PITA. Gotta pull the upper and lower intakes. Bad spot for a part that fails allot.
