How much should it cost to replace a timing belt on 2003 Nissan Xterra. 3.3L 6cyl?

yes there is is the small wheel with a nut in the middle just put a socket that fits and turn on the tighten position it is gonna take tension of the belts good luck

it is a belt....recommended replacement interval is 105,000...but its rubber and it is8 yrs.old might be time to consider it.

Need to replace the Knock Sensor, Very Common issue with these vehicles, quite costly too, depending on where you are located approx. $600-$800 plus.

On a 3.3L engine V-6, Nissan recommends replacement every 105,000 miles, note that this is an interference engine, that piston to valve damage will happen in the event of a timing belt failure.

Xterra with 2.4L and 4.0L have timing chain only, no timing belt.

It has a timing belt, not a chain. Easy enough to check your owners manual. From memory, belt is to be replaced at about 100,000 miles or 160,000 km give or take.

It's has a timing belt, also it's an interference engine, if belt goes bad it will bent valve's .

I recommend 60-90K Cost depends on the dealerships labor but usually when your doing a timing belt, radiator hoses and fan belts are removed and should be replaced while your in there. Its about 3hrs, more if other things need to be replaced while in there. So you looking at $300+ for labor only

If it's the water pump there should be water leaking, if it's the steering pump the noise  would change as you turn the steering wheel left to right. If it's constant, it could be just old belt and bad idler and tension pully. Start buy praying a little water to the belt while the engine is running and if the noise goes away, the belt is in time to be chaged. If the noise is still there, then most likly it's the ilder bering or tension bearing. Good luck

Hi there.What he is probably meaning is you have an interference motor to which means if the belt breaks it will bend the valves or if changing it and not getting timed right will also bend the valves. So if your doing it your self use extreme caution and make sure befor removal of the belt that the timing marks are aligned and the gears do not move until the belt is back on.Rotate motor over slow by hand with belt exposed 2 full revolutions to see if your timing marks a in fact dead on.. The mileage on the truck are close to time to replace.You dont want that thing breaking the belt while its running.You know the facts now.I hoped this helpes you and have a great day...

Yes it is an engine that can and in most cases bends valves if the timing belt brakes
