It should come off. The pulley does not come off on a chevy but i,m not shure about the GMC although GMC engines are not babbit pounders. Try spraying some penatrating fluid on it & tap it with a hammer or wedge something in behind it. If the belt is still on you can try turning it.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
