My father wants me to replace the belt on his 02 4.2 litre f150. Can anyone let me know how to remove the tension from belt. I have not seen the truck yet just trying to get info ahead of time many thanks :santa:

 

Should be able to just put a 3/8" ratchet (no socket) into the square in the end of the tensioner and pull up. Not sure where it is on the 4.2L, but it should be labeled in the belt routing sticker under the hood...

 

If you have ever in your life removed one serpentine belt off of any engine for any reason whatsoever, then you know how to do it. Pretty much every engine using a serpentine belt utilizes the same style tensioner and they all work the same way. I've worked on Frods, Chevy's, Saturn, Honda, Mazda, etc. and every belt tensioner worked the same. Kinda like the childproof cap on a bottle of aspirin, every brand works the same.

 

Breaker bar works best, usually longer and you don't have to worry about the ratcheting mechanism, be sure the new one is correctly on all pulleys, otherwise its will just destroy the new belt. An extra set of hands helps the most.............Also don't forget to post your "watch for flying ratchets" sign.

 

Thanks for the info guys, I have done Pontiacs and Chevys not Fords just wanted to make sure.
