Idler pulley noise (Ecotec)

[VYMAD]

I know that it's possible to squirt some Inox or similar stuff into the noisy idler pulleys which I have done, however this tends to dry out rather quickly. What are your thoughts on injecting a small amount of high temp grease into these?
I thought this might last a bit longer. Or would it thin down too much with the engine heat and spray grease on the surrounding areas/serpentine belt. Cheers.

Why not just replace the pulley? They're less than $30 each i think from Holden and problem solved. Saves messing around with grease and such.

Well I will replace them, but in the meantime, as funds are low I would like to lube them up. It's just that I've only read about using spray lubricant for this and thought grease may be better.
I will replace them when I can because I like to keep everything in tip top condition, as said, it's just for a while until I can replace.

Dont go and be the only ecotec out that that does not have the same rattle as everyone else lol
Any high temp grease should be fine, cant hurt to try is only a bit of grease after all.
Know what you mean with low funds lol, i could buy a few of the bearings from the part but not complete lol

I used a quarter of a can of silicon spray from Repco

Been over a month now of a nice quiet pully

Thanks for replies, guys. Just got to invent something that will squirt a thin stream of grease into the small space. I thought about using a medicine syringe with a small tube attached to the end, so that it will inject the grease right inside to the area where the bearings are. I'll let yas know how it goes.

silicon spray will b ur best temp fix as its oil based so shouldnt dry as quick but saying that its only a temp fix till u get ur pullies replaced. i bought a pack of all 3 pullies from ebay 4 $60 and fitted them myself easy as.

By all three pulleys, do you mean the tensioner pulley as well? Also with 135,000 k's on the clock, is it a requirement to replace the tensioner pulley when replacing the belt?
EDIT: tensioner pulley arm?

As far as I know my tensioner has never been replaced 215000k.
I put a new belt on the other day and could hardly get it on the tensioner is sweet.
Cheers Pete.

Just turn up the stereo that seems to work

as wrx said give some Silicone based spray a shot,,. its worked with mine, lasts alot longer than the WD40/Inox stuff that dries out after a day or 2

Well I made up a gizmo and injected grease into the pulleys. I think my belt might need replacing as it's making a sound that the nearest description I can come up with would be "pinging" coming from belt/pulley area.

If they are the metal type pulleys,you can buy new bearings for them for around $7 each, and just replace them instead of replacing the whole pulley . I replaced the two idler pulley bearings and the tensioner pulley bearing on my ecotec,all for around $20.The plastic type pulleys are throw away once the bearing is stuffed in them.

I`ve got a can of 3in1 but never tried it on pullys.
It saids pullys on the can.

sorry mate if im high jacking your thread but...

Whenever i start my car (VX S) usually for the first time, one of my pulleys squeeks, not constant but i think there is a particular part on one of the belt that when it goes through the pulley it squeeks and then goes away after about 15 minutes, any ideas?

cheers and sorry lol Jonesy

You can take the pulley off and then use a precision screwdriver to hook the seal out of the pulley. Push a bit of grease into the bearing and then push the seal back in. The seals just click into place again.

Yep thats correct if u replace 1 pulley u may aswell do all 3 so u dont have 2 do it later on down the track again. 2 pullies r metal and 1 is plastic. ive done over 250,000kms and they only just started making noise so they should last the rest of the life of the car so a small price 2 pay really.

after i did this i found my alt bearing needed replacing as they were gettin a lil noisey aswell so an extra $15 from an auto elec i now have a quiet motor
