I think my idler pulley is getting ready to die Video

SilverBullet00 · Feb 28, 2008

My car has only made this sound in the past when its cold. Today it was 50* outside and still making this sound. The best I can tell it sounds like its coming from the idler puller, but I have only been around a vortech for the past couple months....

What do you guys think? If it is the pulley, does anyone make a set of billet alum pulleys to replace all 3 of them????

Listen for the pulsing squealing sound ..

It's the belt tensioner for sure. About 90% certain. Mine made that same noise, and it only made it while the car was cold - took about 15 mins of driving to go away. But would still show up when warm once and awhile.
Make sure you buy a ford one to replace it.

Damn! thats going to be a whore and a half to change... isnt there a stronger one that the supercharger guys run??

If I have to take off the supercharger, I still might as well look at getting billet pulleys, as well.

Ford OEM pulley FTW.

You wont have any problems with the Ford replacement tensioner - it costs a good deal cuz it works - i dunno why the stocker goes out

the blower wouldnt make that noise would it? Its now getting worse

CobraRed_96_GT · Feb 28, 2008

you should be able to tell if it's coming from the blower or not - doesn't sound like it is. But use some hose and put it up to your ear to check

SilverBullet00 · Feb 28, 2008

I dont think it is coming from the blower, but my paranoia does ha!

AdRock · Feb 29, 2008

Find a long screwdriver or prybar or something like that. put one end on the tensiner and your ear to the other end. You might have to hunt around a little with it but this will make it much easier to pinpoint where the moise is coming from.

It was the blower

SilverBullet00 · Feb 29, 2008

The blower still makes the ice crushing sound and still whines perfectly, it just has that pulsing, squealing noise. It sounds like a bearing in something..

SilverBullet00 · Feb 29, 2008

Im out looking at it now, I swear to God I hate this car some days.,,,,

SilverBullet00 · Feb 29, 2008

UPDATE:

To make a long story short my tensioner seems to be maxed out and something is squealing pretty loud under the hood. I think its the idler pulley between the blower and the alternator. I called vortech and the said I should be using a 107.5 belt instead of a 107.3. So tomorrow I am thinking about picking up a new belt, tensioner, and idler pulley to help the problem.

Pics of what I found...

Anyone?

BennyBlown2v · Feb 29, 2008

It's probably the bearings in the pulley. Also, a 1073 belt is the part number suffix, not the length of the belt. Just take the blower off and check all the pulleys and make sure they roll smooth etc....

SilverBullet00 · Feb 29, 2008

Im not sure what you mean about 107.3 not being the length of the belt.
i have been reading posts at MPH and they say to run a 107.3" belt with a 3.2" pulley. Vortech says I should be using a 107.5 though... what should I do?

There have been many threads pertaining to the 107.3 thing... It's a NAPA part suffixt, which is 107-5/8th which is the 1073 part number. a 1073 belt works fine! I really don't know of anyplace that sells a 107-1/3" belt anyway

Best bet on finding the right size belt is go into the store and have them take you to the belt rack and let you look, because they will take forever to find the right one if you go hunt/peck style (looking in computer, walking back, lather rinse repeat lmao).

IMO.......fix the idler, and then order an 8-rib

SilverBullet00 · Feb 29, 2008

yeah, I have the napa belt now, and the suffix is 1073. I did a search and everone on MPH said to use a 107.3 inch belt. You are say I should really be asking for a 107 5/8" belt?

The 8 rib kit seems to be a little more than I need right now. I have no slipping problems with the RR pulley.

Btw, how easy is it to change the tensioner pulley? I have never done one before

It's just a single bolt through the middle, then the whole assembly pops off - some years have a 3 bolt though I think?

SilverBullet00 · Mar 1, 2008

Well I got all the new parts - minus the belt.

No one can tell me what size I need. I have heard 107 1/8 - 107 7/8.

Any Ideas?? My tensioner has next to no slack in it, and all I can read off of it, is its a NAPA 25-061073.
