Timing belt? Hi i have a 2003 nissan xterra se 4x4 v6 and i was wondering what kind of timing belt i had and if it has 0% clearance if it breaks. i think that is what my friend said to ask. thanks also i have 91,000 miles on it and its never been changed

No, a 4.3 liter V6 is not a compatible replacement for the 3.3 liter V6 in a 2003 Nissan Xterra. The Xterra is only built to accommodate engines up to a maximum of 3.6 liters. It is important to replace an engine with one that is compatible with the vehicle and meets its specifications. A reputable mechanic could advise on the best replacement engine options for your Xterra.

Hi Slim Jim,Here's a link to a pic where your oxygen sensor is. 2000 2004 Nissan Xterra Oxygen Sensor O2 Sensor Location V6 Engine Here's another link to some new oxygen sensors.Get the exact fit ones. Oxygen Sensor

We're is the camshaft sensors on a 2002 Nissan Xterra SE.. trying to replace both sensors

You most definatly ned to purchase a repair manual, they are not very expensive, auto parts store onlie down loa or a cd on ebay. 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.

The only cure to fix squeaking belts, is to replace with the new one. When the belts start squeaking noise, then it is the time to check the status of the timing belt or chain, depending on the size of the engine.
The 2000-2004 Nissan Xterra was offered with the choice of 2.4L 4-cylinder or 3.3L V6 engine.
The 2.4-liter 4-cylinder DOHC engine was a pretty good reliable engine, but for this truck, it was underpowered. This engine has a long-lasting timing chain - there is no timing belt to replace.
The 3.3-liter V6 SOHC was also a bit slow on pick-up, but for daily use, it was pretty good, durable, simple engine. This engine has a timing belt that needs to be replaced at recommended intervals. The SE model offered a supercharged version of the same engine with more power.

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

do it before the 1 in there breaks and smash's ur valves into the pistons.
there only good for 80,000km not miles .anyways if it's weather'd a few years then god only knows, that's extra wear. change it now before yours breaks.

Normally YES, I would have a new belt fitted and try it just in case. I have had several 'interference' motors break a belt and not damage any valves. Its worth taking a chance before running the expense of pulling the heads off for inspection.

The 3.3liter motor requires 3.8 quarts of oil. 5w30 should be a good oil for the extreme conditions required in your climate. Most new car manufacturers now recommend 5w30w so that says volumes - hope this helps!
