New member here. I tried the search function but couldn't find what I was looking for. On the 2006 Gates shows 2 different main belts based on production month. Can someone help me narrow it down please? Thanks in advance!

 

Assuming your car being an '06 does not have the idler pulley these are the stock part numbers:
Alternator: 11720-4P10A
A/C: 11920-AG900

 

Mine has the manual adjust tensioner. These are the two options I keep getting.

GATES K060465 {Click Info Button for Alternate/OEM Part Numbers} Premium OE Micro-V Belt
Fan, Alternator and Power Steering; Aug. 1, 2005 thru July 31, 2006

GATES K060450 {Click Info Button for Alternate/OEM Part Numbers} Premium OE Micro-V Belt
Fan, Alternator and Power Steering; Aug. 1, 2006 thru Nov. 1, 2006

 

Look at the VIN sticker on the inside of your driver door and check the manufacture date. Then check that date against those dates.
