your chirp is your alternator pulley. the pulley's half against the alternator is moving. replace it with a CB billet one and your noise goes away. a little white grease on the belt also helps
Thanks for that, Anthony. You seem pretty certain. If the front ( fan belt side ) pulley nut is on as tight as it should be, are you saying the back half of the pulley is " wobbling" causing the chirp noise with the belt or are you suggesting it is loose or what, please ?
Further, how much deflection should be in the belt when all is warmed up ? Thanks.
David, regarding your question about how tight the alternator belt should be when warmed up, I can tell you from my research on exploding fans that general wisdom is that a little bit loose is much better than too tight. The John Muir bible says to shoot for 1/2" to 3/4" deflection in the belt.
