When I start my truck in the really cold weather I hear a real bad screeeeeeeeetch - sounds like a warn out fan belt sound. Then it goes away after 10 seconds or so. I took it to my local mechanic and he said it's not the belt it's the clutch plate or something like that? It will cost about $200 - $300 to fix. Funny thing is when its above 30 degrees or so I don't here the sound. I have over 116k on the truck and can deal with the sound if I have too. $300 seems like a lot. What if I ignore the problem : O ? Any help is appreciated. Thx.
