Friday I changed all the belts (Except the recent power steering belt). Also changed the AC tensioner bearing,
Did a quick trip to the Waterberg .
Then on Saturday afternoon on a cold startup had a bit of a racket, sounded like a belt slipping but goes away after about 5 seconds. same Sunday morning , think I woke up the valley.
Last night checked belt, all ok, noise is on startup and disappears after a couple of seconds, lot louder with bonnet open
Spray belts with soap - just to see if one disappears - no - do notice something funny .....
take power steering belt off, noise still there
slacken alternator, noise still there
remove alternator belt, pulley spins without noise .
refit belt - noise back
It's a challenge to start , get back to engine fast enough to put a stethoscope and listen - thus can't really isolate pump or alternator.
took the alternator to get it serviced
However when I sprayed the soap water, the alternator pulley steamed, and when I touch it after startup it feels hot, not scalding hot so I think it might be the bearing spinning?
I hope they find the fault, else there is 2 things left, visco fan and water pump.
