I have a '00 VW Jetta with more miles than I can count (but a new engine, thanks to a JiffyLube faux pas). Each time I start the car, just after the engine catches there is a “whirring” sound - like a belt slipping. The car starts just fine, and runs normally. Anything I should worry about?
Thanks!!
Try and isolate the noise for us.
Stand by the open engine compartment while you have an assistant start the engine.
The ‘whirring’ sound may not be a slipping belt as those usually squeal.
There is a slight possibility the starter (Bendix) gear is hanging up.
If the noise is consistent and you don’t find the noise source right away, have your assistant re-start the engine a few times only, letting the starter rest (cool off) for 10 to 15 minutes after the third try, before trying again.
Post back what happens, ok?
