Orange dust and intermittent squeeling noise

Hi Guy's,

My partner drove the car on a 180m round trip today and when she got back she noticed an intermittent squeeling noise that sounds like front right of the car. When I had a look under the bonnet noticed some orange "dust" around the front right under the fuel filter and around the area with all the belts.


My dad's in Spain at the moment but thinks its a walter leak of some kind any other suggestions?

I think its optical it is straight in the car. I think it might be coolant that has dried hence the powder look?

I think mine is the alternator clutch have a new alternator coming as some other problems I have like intermittent high revs seem to relate to that. Did you have to go through the wheel arch for the aircon pully?

New development today. The Alternator Clutch Pulley fell off today and the inside is completely corroded. Can't get the remnants of the other pulley off so have bought another alternator which is coming tomorrow. I'll get some pics up in a minute.

Any one that has the squeeling noise check out the alternator pulley. As soon as I put the new belt on it the pulley fell off. Ultimately I bought alternator cheap (£84 quid) but if you get there in time you could just change the pulley before it falls off!

Sounds very similar. If you google alternator clutch pulley and look on youtube there are plenty of videos. Does your car ever have a slightly higher rev when still in traffic?

No worries. Do you have any orange powder showing? The belt comes off really easy if you need any help let me know and I'll email you pics of the relevant parts...

No worries, good luck!

I guess if its lower down it could be the aircon unit as someone had above or the power steering pulley?

Good luck getting it sorted hope its nothing too bad!

Sounds very painful, were there any signs of poor shifting? Otherwise thats expensive to look for a noise?
