how is the engine running ?

how does it pulse ?

with the ac on or off ?

can you upload a video of it pulsing so i can see ?

Customer: replied 4 months ago.
there is no AC and it just flutters a bit quarter inch or so while the engine is idling. The engine runs fine maybe a bit of miss can be detected if listened to closely. Nothing to indicate a real problem.

is the belt shredding or coming off on you ? squealing or slipping causing any issues ?

Customer: replied 4 months ago.
All things look OK and running true now but I have only tested for a few miles so far no squealing or slippage.
Expert:  Gary replied 4 months ago.

if there is no slippage or squealing and belt shredding at all there should be nothing wrong with the best system since everything is aligned properly
