Strange noise

Hey dudes,

Took my vitara swimming in dirty water last weekend, and as you can imagine ye olde engine bay got a little filthy. When i got home my voltmeter was reading just over twelve when running. No prob, blasted the alternator with a high pressure hose with the engine running, back to 13.8 volts. Now i recently noticed what sounds like the plastic fan fouling on something when the engine is running, but if i listen closely it seems to be coming from somewhere near the alternator.

Any ideas?

Cheers fellas

I'll give ya a hint ...

It starts with B and ends in "earing" ... perfect example off why mud is bad, mmmkay.

dunno about plastic but I'm guessing the sound is dry and scrapy like ...

no not scrapy, more like when you put your finger on a fan an you get that aeroplane sort of sound, for lack of a better word(s).

Vitara alternators suck when it comes to mud/water. Went through 4 on my old Vit all after driving typical Victorian bog holes.

Might be worth pulling it apart and giving your alternator a clean inside. AC pumps also don't like mud. Neither do oil seals, wheel bearings, queenslanders etc etc

Thanks for the help guys
