I'm sure it's been answered but I just can't find it while searching. How tense do the belts need to be? I have three issues I'm fighting right now and I keep messing with belt tension but nothing seems to fix them.
Issue 1: Belt squeal around 3k rpm and up (sometimes starts around 2500 rpm depending on how much throttle you are giving it). Belt dressing helps but it's temporary as the next day it will squeal again. I've sanded down the pulleys with 180 grit sand paper. I didn't go nuts on it so maybe more would help? Or more gritty sand paper?
Issue 2: Whine. Sounds like I have super charger whine almost and is non-stop but gets louder under acceleration. I'm guessing this has to do with belt tension or possible issue #3 below?
Issue 3: Alternator pulley isn't lining up correctly. I got an AC-Del-co alternator, which was what was on the car. But the pulley doesn't line up with the new alternator. The pulley looked different and I'm wondering if my father-in-law had some alternative pulley that I should of kept but didn't. I've added some washers to the brackets but still it's off a bit. I even added a waster to the fan on the alternator to space it out a bit as well but I'm still off. Should I look into a different pulley for the alternator? I am unsure to what has changed as it did line up before the engine was pulled/rebuilt with the old alternator which as the same part number as the one I have now.
The pic looks like it's too far out towards the radiator but if you look at the pulley on the water pump it's riding the inside edge closer to the motor. The two pulleys don't line up, about 1/8th inch off. I'll try to get better pics later today.
