how to fix belt slipping
 

when i get about 4k+ i can hear this high pitch sound coming from the main drive belts. And i also notice the temp rise to halfway right after i get off it SOMETIMES. I have a dual alt. belt pulley and one seems to be a lil looser than the other which might be the problem, but what are the negative effects of this..waterpump etc, any ideas on how to fix it? btw i dont have an airpump. any advice is appreciated thks!

i assume with your dual belt set up you used the old belt and bought a new one. if it is this the old one is streached out longer than the new one.

buy two brand new belts so they'll be the same length
