The serpentine belt pattern for Nissan Frontier 2005 / how to replace belt

If it's the timing belt you may have it a tooth or two out. Take the cover off and turn the engine till the timing marks are on and see if they are all on their marks. Sounds like you have it out of timing, If what you changed it the serpentine belt .... that's a different story. You may just have something unplugged you never put back.

It has an automatic spring loaded adjuster.

Your Frontier has 2 possible engine sizes, the 2.5L and 4.0. Both diagrams appear below.
Best of luck!

You probably have a frozen belt tensioner arm on you serpentine belt that runs to your air conditioner. Check the tensioner arm for free movement , if it is frozen replace the arm.

When did they start putting gold in a serpentine belt? The serpentine belt only cost about $40 dollars tops. Who told you $4000.00 for this? If it was a shop or a mechanic PLEASE finds a new shop or Mechanic. You could replace the whole front end for that amount of money. I recommend 2 things. 1. Find a different shop or mechanic for doing your repairs the one that told you this didn't give you the whole story as to what they think is wrong. 2. Get a Haynes or Chilton's repair manual on your vehicle model and year from Auto Zone or Advance Auto so you have a better idea of what the problem could be based on the symptoms you are seeing.

As another option, you could post a description of what was happening that made you take the vehicle to a shop to begin with and we could possibly narrow this down to a specific problem that could be fixed. Fact is for 4k I can replace an engine or rebuild one and pocket a lot of money. Even if you had to replace the Alternator ($200), Water Pump($140), AC Compressor ($400), Power Steering Pump ($200), Harmonic Balance Pulley ($50), and Tension Pulley($60), which is essentially everything that is pulley driven on the front of the engine you only come to $1040 in parts add another $1000 in labor and you still don't get to $4000. The serpentine belt itself only cost about $40 in most areas and depending on what has to be removed to replace it about an hour in labor so depending on where you live, to have a shop replace the Serpentine belt would cost about $140 max.

Belt is loose or worn out. If it is a serpentine belt the belt is worn out or the tensioner is defective. If it is a Drive Belt just adjust the tension or replace the belt if it appears to be worn out.
