Small whine when I slow down and brake

Recommended Posts

When driving i do not hear the sound but when I am slowing down and about to brake I hear a small whine that sounds like a power steering pump in others cars but it is in the front. I have no idea what it is. I has been raining like crazy here but I do not know if that has anything to do with it.

Did this prolbem continue? get worse?

Have you taken it to anyone?

I am working with a 2000 Boxster that has a tremendous howl/squeal when the engine is slowly decclerated from above 3000 rpm.

The sound seems to be emitted from the crankshaft - engine front. It occurs without the serpentine belt on the engine.

It continues to emit the sound even after the engine has reached and settled at idle.

It continues briefly - after key off and the crankshaft stops turning.

Mine's squealing - only does it when the engine's at temperature but is really slight - can only hear it at low speed with the hood up. Someone suggested taking off the engine cover and spraying each of the pulleys in turn until the squealing stops. My problem will probably be one of the belt tensioner pulleys or the water pump - doesn't sound like your problem but it is difficult figuring out where these noises come from.
