ZJ 4.0L Serpentine belt remove and install help

Hi I just did all the maintaint on the car, that I can think off. I take car to car care clinic for 28 point inspection, they told me that I need Serpentine belt and 2 rear tires . Good to know that everything arite . So here I am, just bought a gator back from autozone ( the reason I chose this belt its, because I been using it on all my family car for over 5 year now, none need replace ). I usualy pay some one to do it, but I want save some money atm. How do you remove and install this belt and the way its look, do I need to remove the fan ? thanks

The 4.0 has the serpentine tension adjustment built into the power steering pump bracket. All you have to do is loosen the idler pulley bolt below the power steering pump and loosen the tensioner adjuster. Reverse for installation.

And just be patient and make sure you get the routing right.

And maybe I'm just "special", but I had a heck of a time getting mine back on...it kept getting snagged on the fan. I had to walk away from it and come back later to finish it, I was getting too aggravated and needed a cooldown.

My new belt seems to short

Can't get it on the final (power steering pump) pulley, even with the idler in the bottom position, or with the belt off the idler. I think it's routed correctly.

Have I got the wrong belt? It's an Infinity brand, DY923K6, 5060923 (6PK2344).

Yes. And getting the old belt installed again is no problem. Comparing the belts the new one is clearly shorter than the old one. About half an inch longer and it would fit.

belts stretch over time, that's why the old one appears longer. You need to loosen the tensioner as much as you can to get it on.

The gator back might last a while, but what you really want is a GATES belt on that 4.0. It costs more, but worth it. Broken two of those gator backs on mine. Never again. The Gates is a much stronger belt.
