    Re: smog pump adjustment

    If I remember correctly, its located at the rear of the pump. Seems like its adjusted from under the car . I remember it being akward to reach. Loosen the upper attaching bolt on the pump then look from under the car at the backside of the pump for the bracket adjuster bolt. This if from an old mans memory! sounds like you've got the belts routed correctly.
