Ok, I just got my s-10, its an 01 with 26,000 miles on it, 4.3 liter v-6, superchargerd, with headers, and customized out the wazoo, anyways, when i start it i head a loud screaching noise from the side with the supercharger, i have noticed that after sitting still for 15 minutes the temp gauge reads near 260, and i have had trouble starting it now, just this morning i revved it to about 4000 and i got white smoke puring out the tailpipes, can anyone help me?

 

you have a blown head gasket, cracked head, craked block

 

^^^ what he said

it also sound like your belt is sqeaking, maybe a bent pully or somthing like that.

 

yea we have determined the smoke was from antifreeze but we cant figure out wich belt is loose

 

get a bar of soap and run it on the belt (BE CAREFUL)

you'll know what belt the squeak will stop

 

you have a blown head gastket but your worried about the belt? Just replace them when you tear into the motor and you will not have to worry about it. for peice of mind you might consider checking each pully to make sure that none are locked up
