WhiteOut Posted June 25, 2004 Report Share Posted June 25, 2004 You can borrow a pulley removal tool from any Autozone store. Quote Link to comment Share on other sites More sharing options...

Heza Posted June 25, 2004 Author Report Share Posted June 25, 2004 why yes...yes i did! i used a vice grip on the fly wheel to stop it from moving and then popped the center bolt loose. after that, i did the other three bolts. got the belt off...after thinking about it and talking to you Shane. i went and got an offset 15 mm box wrench...took my other huge socket for something else and put a 1/2" extension in it to gain leverage. put new pulley on, new belt on, redid all that damn splash shielding and took a test drive. my observations are: for those without a FFP UD pulley on the 3.4...get one ASAP. its an easy bolt on now that ive done it. not only does the engine feel peppier throughout the entire RPM band, it actually has a little less of that infamous DOHC lag from 0-40. my next step is to get the FFP dogbone to hopefully attain better engine response.

stockgp Posted June 26, 2004 Report Share Posted June 26, 2004 just fyi for you guys, there is a little square hole on the tensioner towards the pulley end that a 3/8" drive fits into. so all you have to do is turn the wrench and the belt comes right off. of course i have never worked on a 3.4, so i am assuming the tensioner is the same as a 3.1 Quote Link to comment Share on other sites More sharing options...
Aaron Posted June 26, 2004 Report Share Posted June 26, 2004 That doesn't sound right. I used a big wrench, it is like a 18 or 19mm, and just pushed straight down and had a buddy pull the belt off of the PS pump. Quote Link to comment Share on other sites More sharing options...

That is exactly how i had to do it Quote Link to comment Share on other sites More sharing options...
Aaron Posted June 26, 2004 Report Share Posted June 26, 2004 Yah ti is tight so there isn't much room to get the wrench in good position, so the belt doesn't loosen up much, so you need a buddy to pry the thing off. Quote Link to comment Share on other sites More sharing options...
Heza Posted June 26, 2004 Author Report Share Posted June 26, 2004 the pulley bolt on the tensioner for my 3.4 is a 15 mm. the bolt for the tensioner is 13 mm. i got a 15 mm box wrench, extended it, and took the pulley off and put it on myself. maybe they made it easier in '96?

stockgp Posted June 26, 2004 Report Share Posted June 26, 2004 well like i said, i've never worked on a 3.4. it's probably different. but on my 3.1 i used a 3/8" ratchet, no socket just the square end. i was able to do that and remove the belt myself with no problem Quote Link to comment Share on other sites More sharing options...

sonyman87 Posted June 26, 2004 Report Share Posted June 26, 2004 yep, 15mm if i remember correctly. Its exactly 19mm or you can use a 3/4 and if your a little guy you want a cheater bar on your wrench atleast 20inches to make it easy simple to get the belt off. once you get the wrench on push down in clockwise motion and with your free hand grab the belt off the power steering wheel. your gonna wanna get a belt atleast 1 inch shorter then stock.. i recomend 2inches shorter to keep it from maxing out the tensioner and get the squeeling sound.

joey b Posted June 27, 2004 Report Share Posted June 27, 2004 72" belt for '94-97. 71" belt for 91-93. i have a 72" belt and it works great. Is the 94-97 pulley larger than the 91-93 or is the belt drive different? Quote Link to comment Share on other sites More sharing options...

Is the 94-97 pulley larger than the 91-93 or is the belt drive different? not sure, but i think the '94-97 might have a different accessory routing/difference somewhere.
