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.

Diagram? I don't understand your request. Are you replacing a drive axle or a driveshaft? One is easy, one is very difficult. Both are tough if you've never done one. Be careful.

I have a customer with a 2000 Nissan Xterra 3.3 liter V6 with 180k miles. He stated that while driving on the highway the vehicle is fine. Once he exits the highway and drove on surface streets the engine stumbles, sputters and shuts down when he stops. The fuel pump is located under the right side rear seat. I removed the inspection cover to view the electrical connections. No problem there. I drove the vehicle for approx 20 minutes and it hesitated a little but not enough for me to come to a good conclusion. I needed the engine to heat up some more so I drove to Panda Express for lunch. I got my lunch to go, return to the vehicle and started the engine to eat while the engine idled. After my lunch was over I drove back to my customer's house. On the way God bless me with what I was searching for...the engine started to sputter. To shorten this story I replaced the distributor with a brand new assembly from AutoZone($233.65). Once I removed the factory distributor I spun it by hand and that's when I could feel that bearings were rough & worn.
Problem solved and my customer is happy.

Hello the sensor is located under your intake manifold you will need to remove the intake manifold to gain access to it here is photos of what and where your looking for this

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.

Did you ever find an answer to this problem? I am interested because I also have a 2003 V6 4-Motion Passat and am having similar issues. I only have 86,000 miles on it, but I'm sure if I have to end up replacing the transmission it would not be worth it. I'd be interested to hear what ended up happening with yours. Thank you!

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

try disconnecting the MAF (mass airflow sensor) - it is located after the air filter, usually a black box in the intake tube. Could also be the IAC valve which monitors the engine temp, that can be disconnected but will cause high idle if removed, dont know where it is on your car though.

If the MAF is faulty, disconnecting it will make the car idle and run again, but will generate a CEL (check engine lamp) on the dash just because the MAF is not seen by the ecu, but it will run on a default map till you get another one fitted.

inner timing cover y shaped oil gallery gaskets..make your own or order the complete cover..costs from nissan are 500 canadian for the cover and around 1500 total for the replacement.oil pressure goes back up immediately after the install..alot of work to replace a cheezy piece of paper...
