1985 buick century custom

check each pulley for issues like rough surfaces pits and sure most of the pulleys turn by hand to some degree with no resistance( or very little) the alternator, water pump , powr steering and ac clutch pulleys should turn free.. if not, find out why.. also check for almost ferfect alignment..they should all be straight in line with each other if not find out why..repost findings..

Olds 307 Belt Diagram

307's have a unusual routing, it's easy to get confused.

From back to front:
1) Crank - Water Pump - Air Conditioning
2) Crank - Power Steering - Water Pump
3) There are two versions, depending on how many grooves the power steering pump has:
(1-groove P/S):Water Pump - Alternator
(2-groove P/S):Crank - Power steering - Alternator - Water pump
4) Crank - Air Pump

There are 2 belts - one for the air conditioned equipped engine (diagram 6-3) and one without the aircon (diagram 5.3).

Next go to the second document - Illustration guide PDF document - for those 2 belt diagrams.

How to change a water pump on a 1999 Buick Century 3100?

the water pump on the 3.1 isnt to hard to change ...
  1. Disconnect the negative battery cable.
  2. Partially drain the cooling system into a suitable container.
  3. Remove the drive belt guard.
  4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.
  5. Remove the drive belt. Remove the water pump pulley bolts and remove the pulley.
  6. Remove the water pump bolts and separate the pump from the engine front cover.

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
