This was very easy. I am not a mechanic and this only took me 30 minutes. I would put the complexity not far above doing an oil change. Sorry that I mostly t…

Hey John, thanks for the video. I am not a mechanic either but between
your video and talking on the phone with my best friend (who is a mechanic,
but lives 4 states away) I was able to replace my idle pulley on 2002 wrx
wagon. A very simple job and saved me about 80-100$. The part was 32$.
So thanks!

I have the same problem, but did you lose any performance when you drove
the car before you replaced it? I kinda feel that with mine. I’m just not
one hundred percent sure it’s cause of the faulty pulley. Great
instructional video man!
Hi. A bad pulley would not cause a noticeable drop in performance. If it
did the bearing would heat up and melt and you would know all about it. I
have had loss in performance in my car due to the knock sensor, low octane
fuel, 02 sensor. Being a highly strung turbo the computer is pretty fussy.
If you dont have a boost gauge, get one. This will tell you a lot about
what is going on.
I have an 02 wrx and it has a boost guage. Im gonna replace the pulley
tomorrow but that probally wont fix my lack of performance. My CE light
isn’t even on so its hard to say what it could be. Somtimes when i go into
first, it almost feels like it misfires and takes off but without as much
pull. It’s only sometimes though. Not really sure what to do. Maybe i
should just take it in to get it checked by a tech
Well done video including the closeups of the belts/pulley. My subaru has
the same whining noise and I’m hoping it’s this Idler Pulley.
Thanks. It makes a pretty bad noise. I was pleased when it turned out to be
such a simple fix. Good luck!
what part number was the roller you used?
My 04 wrx is making that same noise the whine.. And it gets louder when you
rev.. I hope its the Idler pulley and not the Timing belt tensioner.. Even
though I have already had the timing belt replaced
