is there any way to add a spring loaded idler pulley, so that i dont have to loosen the bolts on the power steering pump and use the adjusting bolt?

And so it follows that all are? Ya... that's logical.

Most if not all 4.0l ZJ's use the P/S pump and bracket to adjust the belt. The 5.2/5.9 uses a spring loaded.

Why are you loosening the power steering pump bolts? All you do to adjust the belt tension is loosen the 15mm nut on the idler pulley then tighten/loosen the long bolt in between the pump and manifold. Takes 10 seconds with an impact.

My engine is out of a 95 zj, it has no tensioner, tension is adjusted at the power steering pump. The two 93 zjs I have owned with 4.0s as well as my dads, all the same.

Could you maybe upload a pic?

Hmm. Didn't realize there's more then one setup on the 4.0L

The first picture is the idler pulley that you loosen, then the second picture is the adjusting bolt itself.

That's how the 2.5L YJ works as well.

Ya, I kinda want to try and convert to the WJ setup hehe. It's possible that all you would really need is the alternator bracket, belt, and tensioner.
