Need to know the steps on how to set the timming on a 1991 hona civic

FIRST:
Click on the following free direct Link. It has the Serpentine Belt Diagram and Tensioner location for your specific 1.5L or 1.6L Engine and options (AC/No AC etc.).
It also has the directional diagrams on how to rotate the Adjustment Bolts on both the Alternator and Power Steering to loosen the belts, inorder to both remove and reinstall the belts.

I would also strongly suggest purchasing either a Haynes or Chilton Manual, available at most auto parts stores. It has specific information you will need incuding the Torque Specifications for each and every Bolt and Nut you will be removing. Cost is $20-$25 fo the manuals.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!
