Pulley Cover Gives Smooth Screwless Appearance, Newly Designed Fan And Baffle, Complete w/Chrome Baffle For Stock Chrome Fan, Fan Produces 20 Percent Increase In Cooling, Pulley Produces Higher Amperage Output At Low RPMs
What advantage does this fan cover have over an alternator that just has the fan.
My new alternator 8-37140-344 has the cover and I am wondering does it keep it cooler over one that just has an open fan
Answer this question
It is for appearance just to dress the engine compartment up a little.
