Struggling to remove 18 MM bolt from belt tensioner pulley on 1992 Buick Century 3.3 Custom Station Wagon so I can replace wobbly pulley.
The same bolt and a socket is used to loosen tension on the serpentine belt.
So, how would you block the tensioner arm from springing up while you try to remove the bolt on the pulley? Would you use a block of wood between the tensioner pulley and the power steering pump pulley? Or would you use some sort of crowbar or large screwdriver.
I read that the bolt in the middle of the pulley is a monster to get loose.
Not as strong as I used to be and do not have an air compressor or impact wrench.
Any comments or suggestions are very welcome.
