Hey,

so when replacing my alternator, I have two options from auto zone.

130 AMP alternator
or
150 AMP alternator, with clutch pulley.

which one can I use? Does it matter?

When I see clutch I think of a manual transmission...
thank you in advance!

 

Use the part number you pull off the old unit to determine 130 or 150.

 

I would think the alternator would not be rated higher than the main fuse but certainly could be equal to it.
Thus the main fuse could offer some insight by pulling the black cover next to the battery.

FWIW - 2013 F-Sport 350 shows 150Amp...

Edit - another option is to enter your VIN into one of the many Lexus/Toyota sites and look it up that way. You should get a warm fuzzy....
