Fan belt on any model a should only be tight enough so it doesn't slip. Doesn't require much tension.

While I agree that you should not overtighten the fan belt as the pump bearings can't take it, I will advise against too loose IF you are experiencing overheating in traffic or in a parade.

My car was overheating and the belt was at 1", and I noticed that there were shiny spots on the inside of the fan belt. I tighten the belt to 1/2", put some belt dressing on and the overheating stopped.

That is my experience.

About 'perfect' when the belt has 1/2" deflection in and 1/2'' out from straight position.
BTW...use the 'longest' length between pulleys to gage this deflection, not the shorter areas.

BTW...You will have better belt grip and wear from a cogged belt, your choice.
