1979 chevy c30 steering belt adjustment - 1985 Chevrolet C3500

It may have a threaded rod through the bracket to tighten the belt . A nut on the end of the rod can tighten or loosen tension .

its timing belt

I would suspect the water pump, power steering noises are usually grinding sounds. Also if the belts shredded check behind ALL the pulleys for the reinforcing strands from the belts. Basing this on general car problems , not any actual Chevy.

Loosen all items that move to adjust belts and replace all 3 while you are at it.

Depends on which belt..if it's the alternator belt, out's just a matter of loosening 2 bolts on alternator, sliding alternator towards center of engine and removing belt. Installation is the reverse.

you may have two problems ,one could a bad ground either body or at the battery.or the sending unit is faulty inside the tank.check the grounds first.

IF YOU LOOK CLOSE YOU ARE PROBABLY MISSING THE NUT ON THE VERY BACK OF THE PUMP. USUALLY HARD TO GET TO. YOU USUALLY HAVE A PIVOT ADJUSTMENT FROM THE FRONT SIDE (TOP), A SLIDER ADJUSTMENT IN THE 9 O'CLOCK POSITION FRONT SIDE, AND ANOTHER SLIDER ADJUSTMENT ON THE BACK.
