Installed my 2.85 on there,and ever since tensinor is making a noise like if its loose or something..there is no belt slippage,just makes noise when idling..stock tensinor pulley..i can move the tensinor pulley left and right with my hand..any fixs?

 

sounds like it might be going bad

 

do i need a new tensinor unit,or can i buy the kit from cobalt-addication..says its perfect for 3" pulleys or smaller

 

bump?

anyone have a answer..its starting to **** me off and my belt is slipping

 

zzp adjustable tensioner should do good

 

had the same problem...its just the cheap casting from Chevy and now the tensioner pulley has some freeplay bc of the journal that the pulley rides on.....nothing you can do...I replaced mine....problem came back.......I even went back to a stage 2 pulley from a 2.85" to see if that would help....try ordering just a new pulley.....i.e. just a new pulley with bearing not the tensioner bracket........On an unrelated note: I recently went back to 2.85" bc now I have better cooling mods and I rebuilt my s/c.......but I'm used to all the rattles and knocks that the ecotec design, and even the eaton, makes......As long as she runs and is reliable I wouldn't worry too much........

 

i got belt slippage,and its gay

 

well then you do have a problem...as the others listed above...you need an adjustable tensioner brakcet to take up the slack...........

 

well i just ordered the zzp adjustable bracket..does it come with the pulley as well or just the bracket

 

its just the bracket...to get the pulley u can go to your local auto parts store and order it...and it'll arrive there at the store the next day no charge...........

 

cant i use the one from intense website site..

its only 20 bux,i bet its prolly the same price at a local auto store

 

u mean the oversized tensioner pulley...I'm not sure...and..I'll tell you why...I bought that and shaved a tensioner bracket for it to fit with a bench grinder...and first off the tensioner bearing still seemed to have a lil play in it...even though it was brand new.......also, when i went to put the belt back on the car; it wouldn't fit over the stage 2 pulley...I even tried swapping back to the stock belt instead of the shorter stage 2 belt.......didn't work...I never tried getting it to work for a 2.85" but from how much more belt I needed I'd say u'd probably have to run a 2.7" pulley for that oversized tensioner pulley to even work.......your best bet is the adjustable bc I you want to go back to stock you can adjust it there...3.0"-2.8" adjustment is there, and if you want to run smaller the adjustment is there....its an all around win/ win situation since there are 3 hole adjustments and you need to make sure you eliminate belt slippage........anyways merry christmas I'm gettin' my ass off here.....good luck

 

i bout both,it was only 20 bux..hopefully it will work out fine
