Serpentine idler pulley

[LAJ]

Got a 94 3.0 ranger with 180K on it. Idler and tensioner have never been changed. Bought a new idler (Dayco 89003-only thing available anywhere) but it is 1/2 inch smaller than the original. Looks like it might not be a problem but the tensioner will have to take up more belt. Has anybody else run into this? Thanks.

Try this number, I have an 01 3.0 Ranger and this tensioner is spot on to stock, not sure if they changed designs between the 94 and 01, nice quality part though, check it out.

Need help with idler

I think I may have a 4.0 idler since it is a 1/2 inch bigger than the 3.0 replacement idler. Those guys at the plant must have been swapping parts when the engine was built. The replacement tensioner pulley seems to be correct. So I'll probably need to change my belt even though the present one is only about 2 years old. Thanks.
