So i need a new alternator and I went by Auto Zone and they asked me if my car needs the one that says "F" or "D".. I was like wtf?? So I got online and looked it up...

which one of these do I need??

4 Cylinders D 2.0L MFI Turbo DOHC
4 Cylinders F 2.0L MFI Turbo DOHC

There is a price difference between the two..


EDIT...

did a little more digging around on auto zone's website and learned the "D" one is for a 4 groove serpentine pulley and the "F" is for a 6 groove pulley. Went outside and counted the ribs on one of the other pulley the belt goes around and it seems like it's 6. definitely more than 3. Good thing, the F one is like $200 cheaper..

 

$200 cheaper, gasp! Have you considered just having yours repaired? Every town has a shop that fixes these things and they usually come back as good as new.
