Hey guys I have a 95 302, i recently deleted my smog pump (which I was very pleased with) and I purchased the ford performance air pump idler pulley in hopes of keeping the stock belt size and routing. The original belt “works” but it is looser than it should be. I was wondering if anyone else has done this with the use of the additional idler rather than just rerouting the belt and has a belt size they’d like to share.

thanks.

Did you replace or check that the belt tensioner is still functioning properly?

Get the Dorman 419-644 Drive Belt Idler Pulley and put it on in place of the Mustang idler that comes with the idler kit. It is the exact size of the Bronco / F150 sag pump pulley.

yes my idler is still functioning properly, it was replaced about a year ago so i know that is good. I ended up playing a guessing game at orileys testing out different sizes and I was most happy with a 98 5/8" belt over the stock 99 5/8" belt. thanks
