My 91 350LE has been running warm so I decided to restore the cooling system. I pulled the radiator and sent it out for rebuild. I plan on new hoses, belts, fan clutch, thermostat, and water pump. I noticed when I got to the belts that the a/c belt rubbed the water pump and now that I have the new GM water pump installed I can see that the belt rubs this water pump at the lower outlet as well. Any ideas? The pulleys all line up perfect so I don't think shimming that water pump pulley is the right thing to do. I may try to grind off some material where the belt fouls but I am worried I would grind through.
