Squeel on start-up
 

I replaced my serpentine belt a few months ago, and lately when I start my Boxster I get a squeel. I did not replace any of the belt tensioner bearings. My Boxster has 68,000 miles and I know from previous belt replacements, something usually will go bad not long after. New belts are very tight and put a lot of stress on a part getting ready to go bad. Which part do you think it is. Me, I was waiting for it to get constant so I can hear exactly which part it is. :rolleyes:

Apart from the belt slipping (which it shouldn't as the tensioner should be - er - tensioning), the rollers usually get noisy when worn, only shreaking when siezed. The next thing to look at is the starter. Lots of people report that the starter gives a short, loud and horrific shreak for about a second as the bendix engages. The fix is to remove the starter and clean off the crud.
That's assuming the neighbours cat isn't missing......

Is this the sound your car is making? It's the starter motor then. Check out this thread if so:

My '02 S w/73k miles started doing the same thing about a month ago. 99% sure it's the starter. I was thinking I'd have to drop $150-$200 on a reman., but not any more... Yeah, baby! :cheers:

Search the forum for starter DIY. One thing I learned is to remove the interior access panel too. With long extensions, you can get to the starter bolts. Its close to impossible to get them from the top (I did but it was not fun).

:rolleyes: It is not the starter for sure, since it makes this noise after the engine starts. Sometimes it will squeel after running for a while. I know it's a tensioner or a idler, but which one is the question. I am going to run it for a while a see if it gets constant which will make it easier to pin point.

Could be the AOS going bad. Email Jake Raby about it. He saved my Democrat (ass).
