Cas Noisy (23731-5L300)

[bentwagon]

Start the engine, grab a hose and lightly start spraying water on and around all belts/pullies and see if noise changes/stops.

Finally managed to do this the other day - noise stops for a second then continues.

Quick q - does the cas on a series 2 require the cas seal?

kind of, in the seal are 3 brass standoffs, they space the cas out the correct distance to stop you loading up the thing and breaking it

When the noise stopped for a second, where were you squirting the water ?

Just randomly at the belts...

Over tensioned belts..simple as that

Hopefully, might have to loose them off a bit and see. Cheers.

With engine off see if you can twist a A/C, PS or Alt belt more than 90degress with one hand. If you can, tighten it up. It May also be too tight and back off a touch if necessary.

Can you isolate it to a single belt perhaps ? Using a glass of water just slowly dribble it onto 1 belt and listen for change. If no change, move to next belt.

So, took it to the mechanic - needed brakes done - and they said the noise may be power steering needing a flush, either that or its the pump. Tightened belts a little but noise still there. Now to research how to DIY power steer flush...

drain the res and refill

repeat every weekend until the fluid stays clean?

Have you tried yet what I mentioned earlier about narrowing down which belt made the noise ? Get a plastic drink bottle and drill a small hole in the lid. Just do one belt/ pulley at a time and wait 20 seconds before trying next belt. You know the sound went away when you hosed the belts. How can this then be caused by PS fluid ? ones internal, the other is external.

Did you twist the belts and see how far they twisted ?
