SOURCE: crankshaft and camshaft sensors location in nissan altima 2003

You are incorrect sir. There is a very good Youtube video showing you exactly where it is that is how I changed mine. The Crankshaft is located behind the engine block below and around from the cam sensor which is easly spotted looking at the engine. The crankshaft is in a difficult spot but once you figure out where it is it's easy...ish hope this helps

First of all, you'll have to clarify which belt it is you're talking about. Is it a SERPENTINE drive belt or a Timing belt? Two totally different belts.
If its a timing belt, you're in luck as Nissan Altimas have timing chains on the engines which shouldn't need replacing for at the very least 100,000 miles. If you're talking about the serpentine drive belt on the other hand, there's really only one way it can go over the pulleys. One side of the belt it grooved, and one side is smooth. There's only one way it can go over all of the pulleys while having the grooved face sitting on grooved pulley surfaces,... should be really easy to figure out.

SOURCE: engine is misfiring. 2.5L 2003

one of the small screws that secure the plates to the shaft of the swirl control system inside of intake manifold mostlikely fell out and wound up in the cylinder of the damged plug causing the damage to the plug.there was a recall by nissan to remedy this by replacing screw with threadlocker.contact your local dealer for info.

Hello and thank you for using FixYa!

The knock sensor is located on the back side of the engine block by the oil pressure switch, under the intake, but accessible from underneath the car.

2003 Nissan Altima 2.5S, Check Engine Light Problem.


this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.
