Hey guys. Just changed the serpentine belt on my 88. Fixed the squeak! When I first started her up I had a weird urge to feel the spark plug wires while it was running and I could feel a weird surging while it was turning over. So I turned the truck off, took the wire off the plug and the plug was loose! AND all the others were loose... wow. Torque spec fail. I'm guessing I need to wait for the motor to cool down to tighten those back up. Actually Im going to take them out and check the gap. Just a heads up to check them plugs y'all.
