This is a basic question which I can't see to find an answer for in the service manual. Most of the videos online assume a tensioner pulley is in the mix. I rerouted my heater hoses so they are correctly positioned. I checked the belts and they seemed to have play in them. To tighten the belts: 1. I stood at the passenger side fender 2. Leaned over and used my left hand to grab the underside of the alternator 3. Used my right hand to loosen the 1/2 inch bolt at the top bracket of the alternator 4. Gave a mighty pull with my -non-popeye left arm 5. Quicky tightened the 1/2 inch bolt with my right hand There is still play in the belts, just not as much. How do you properly tighten the belts? and How do you know when you have them tight enough?
