Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone. Every now and then when I start my Car up the day after I parked it, mostly when cold outside I get a squeal / screech from the engine area. Sounds very much like a belt on a pulley. The aux belt is new and tight. Any ideas ? Could it be something the belt powers? The alternator is new. Does not screech once started Thanks[/b]

POST 2Original post

Mine was doing this and it was a dry bearing in the starter motor. Replacing the starter cured the issue.

POST 3Original post

Yep, sounds like bendix throw gear/bearing is dried up and not returning on startup, my 996 does this sometimes on hot start :grin: Whip the starter motor out and give it a service :thumb:

POST 4Original post

Yep definitely the starter. Build up of dirt and clutch dust get in and the teeth don't retract fast enough when the engine fires so the starter gets a good spin from the flywheel, hence the noise. General consensus is to thoroughly clean but not lube as this just collects dust and dirt causing the same issues further down the line. Its simple to remove on a Boxster, not sure about the 996

POST 5 / ORIGINAL POSTEROriginal post

Thanks everyone .. much appreciated

POST 6Original post

If its the starter .. which i expect .. it's a very loud whining screech that happens for 2 seconds just after you let go of the ignition key. If it's more a squeal that lasts say 10 seconds then its belt related . It is possible to remove the starter , clean and free off the bendix and refit .. i would consider the cost of a new starter motor though as if not huge then replacement might be best .
