The ALT pulley is smaller too in such way that the rotation speed of the alternator stays the same than the factory lights. Dont worry about alt drain problems.
A/C works the same on idle as before, water temps stay on the same spot than with the stock pulley I didn't notice any difference on the accesories of the car.
We tried to follow
this guide but the bolts of the alternator were very tricky to deal also the cranck pulley bolt was very hard, neither the impact pistol or the big hand ratchet were enough. We use the power of the car starter, the mechanic put a ratchet with a the corresponding socket on the crank bolt and by starting with a lot of care to not turn the engine on, we were able to unbolt the crank very fast.
You dont learn that on school.
