belt tensioner

[herzog racing]

I brought my 02 wrx in to have it looked at for the belt becasue it started making noise and they said it was the belt tensioner. I am confused as to what belt tensioner I need because would this be considered the timing belt tensioner like this one shown here? or would it be considered a serpentine belt tensioner?

It could be either. Ask the person who told you what it was. Or check out the belt tensioner, as it connects to the ac belt and is easy to check.

I will take a pic of it and post it in an hour. I can't find serpentine belt tensioner

I have seen both of them make noise, def. find out which one they are talking about...

[herzog racing]

I am almost positive its not the timing belt. I think its the a/c belt tensioner

took a better look at it and found this. Where can I buy this?

A\C tensioner. You only have to buy the pulley though, the "tensioner" is fine, the pulley is bad, very common on these cars

Go to the dealer, the are about the same price as aftermarket, usually dealers will stock one or two of them, while you are there make sure the little plastic piece that the adjuster bolt goes through isnt damaged either.

Hey guys im kind of having the same problem.... my belt (timing) keeps comming loose and i bring it to the dealer and they tighin it up and everything but it keeps happining and they dont know why???? They keep fixing it for free but is kinda a pain in the a$$ to keep bringing it back there. Is there something there missing or not telling me? has anyone had this problem? By the way it's an 04 wrx Thanks.

Sorry I don't understand how the timing belt could come loose, how to tighten it, or why. Are you sure it's the timing belt? Do you have an invoice from the dealer listing the repair done, and what parts were involved?

[craighardy1313]

Yes it's was under warantiy so there was no invoice's for them tighting the timming belt but i had the timing belt replaced then it started a few months later and they just kept tighting it for me.

[SD_GR]

Again, I see no way literally and physically of tightening the timing belt. The tensioner is hydraulic. Once the grenade pin is pulled it simply expands and tightens the belt. Tension is then maintained for the life of the belt.

Are you sure it's not an accessory belt we're talking about? If it's an accessory belt, replace it with an authentic unit, and replace the roller(s) too if need be.

[craighardy1313]

Alright thanks! I will defantly take another look at that!!!! maybe i just miss read what they did. Thanks again

[craighardy1313]

Yes i just check it out and it was my drive belt due to the alternater pully going bad. so here is my question we had the pully and the belt replace in march on 2010 and its now having the same problem if they had replaced everything the first time then why is this happening again just a year later?
