the car will sometimes chirp at idle but it will squeal when accelerating all the time until the engine has fully warmed up then it will suddenly stop what could this be? power steering pulley, idler pulley, and crankshaft pulley have been replaced along with the serpentine belt

if this helps i think when the mechanic put the crankshaft pulley on he didnt clean the grease off of the pulley, could that cause my belt squeal?

Go to the thread in this Forum "N* making a purring or growling noise". Read Post #47.

There's also the tensioner bearing and the alternator bearing, less likely is the a/c pulley bearing. The tensioner pulley can be replaced just like the idler if your tensioner is still good. I've had an occasional squeak from my alternator bearing, especially if it's rained, but like yours it stops as soon as the engine starts to warm up (the grease in the sealed bearing loosens up).

The alternator bearing can also be serviced, if you can find anyone who still works on them. But with labor to remove and replace the unit, might as well just replace it.

But it should be easy to pinpoint which device the noise is coming from. A stethoscope would be handy, or carefully use a length of vacuum hose.

well the a/c compressor is in the trunk and there is a bypass pulley were it used to be so i have it pinned down to a few things the famous N* oil leak but it only leaks very little on the oil pan, a bad tensioner pulley or arm, bad alternator but the battery stays charged properly and i also checked the alternator before and its in working order, could be an over pressed power steering pulley, pulley misalignment, or the belt could be to tight since its aftermarket and thats all i can figure out

 

[mhamilton]

Well the alternator front bearing wouldn't have any affect on the alternator charging (unless it completely seized)... it's just what supports the pulley and the strain of the belt tension. It's a little sealed bearing just like what's in the idler and tensioner hubs.

The belt can't be too tight, the tensioner is automatic and would only get weak with age.

i got time today and checked out the noise, i checked the tensioner pulley and looks to have a kink in it and when it hits that the belt chirps so i think the bearing are bad in the pulley

What you need is Gates Part # 38006 http://www.rockauto.com/catalog/moreinfo.php?pk=3669

You have to discard the original dust shield when you install the replacement, the shape on the new one will interfere with the shield. Just use the bolt by itself.

 

[Mafiaman111]

now is it possible to take the tensioner pulley off without taking the tensioner arm off?

 

[Submariner409]

No, because I think the tensioner pulley retainer bolt faces the front of the engine block

 

[mhamilton]

Edit: Oops, Sub beat me too it!

It only take a minute to remove. There's nothing to it. Just remove the belt, remove the one bolt, and the tensioner just falls right off.

 

[Mafiaman111]

then when i put the tensioner arm back on do i have to do anything special?

 

[Submariner409]

Bolt the tensioner assembly back onto the block, use a breaker bar socket handle in the square hole to lever the tensioner, install the belt, and gradually release the tensioner against the belt. Make sure the belt is properly in ALL the pulleys that have grooves.

 

[Mafiaman111]

ok thanks i hope this is the end of my serpentine belt noise cause if this does not fix it then it will be down to the alternator

 

[Mafiaman111]

also does an idler pulley and tensioner pulley need proper torque or no

 

[Ranger]

You mean on the mounting bolts? No, not that critical. Just torque 'em down.

 

[Mafiaman111]

ok thanks i have been having this annoying chirp or squeal its different everyday haha for 5 months and i have went threw a good deal of money fixing problem parts and the chirp or squeal will not go away, so this time i need to find every possible cause so i can fix it this time thru

 

[Mafiaman111]

i took the tensioner off and now i cannot get the bolt that holds the pulley on to budge

 

[mhamilton]

Do you have the tensioner arm in a vice?

Worst case, just replace the entire tensioner assembly.

 

[Submariner409]

A vise is used to squash the fingers of the Vice Squad. :cool2:

 

[Mafiaman111]

well after examining the tensioner arm for a while, the tensioner arm looks bad its all covered in grease, gunk and it pretty stiff plus its the original tensioner arm on the car so i have decided to just replace the whole assembly
