I have a Subaru Forester X Limited AT 2000cc 2AB 2009.
The timing belt requires replacement.
My question is if the Gates TCK304 Timing Belt Component Kit, fits my Subaru?
O'Reilly's compatibility chart for the Gates TCK304 shows your vehicle under the compatible vehicles. In addition, Amazon's compatibility seems to say the same thing.
Are you sure that you have a 2000cc (2.0L) engine? The only match I see is the 2.5L for that year and trim.
Edit: it turns out that there is a 2.0L version of this car, however it seems to be slightly obscure, and O'Reilly doesn't have it in there car list.
Per the OP's comment: The replacement part is: 13028AA240 for Subaru Forester X Limited AT 2000cc 2009
