Our take on the Subaru OEM Serpentine Alternator Belt for 2022+ WRX (23780AA070)

This is the genuine Subaru accessory drive belt that runs the alternator on the 2022-2023 WRX, part number 23780AA070. It fits both CVT and manual cars. As an OEM part it matches the factory belt in length, rib count and material, so it seats on the stock pulleys without shimming or guessing. Aftermarket belts can be cheaper but vary in rib profile and compound; this one is the safe choice for a stock or lightly modified car. It is a wear item, so buy it for scheduled replacement or as a spare.

Questions and answers

Will this fit my 2022 WRX with a CVT?

Is this the same as the belt that came on the car?
It is the genuine Subaru replacement, part 23780AA070, so it matches the factory belt.
Should I replace the belt as maintenance?
Belts are wear items. Replace it at the interval in your owner's manual, or sooner if it cracks, glazes or squeals.
Do I need to confirm the part number?
Yes. Check your VIN against the part number before ordering, since Subaru can change parts by model year and trim.
Can I install it myself?
On most Subaru engines the accessory belt is a straightforward job with basic hand tools, but the WRX belt routing and tensioner should be followed exactly.
Where is the Subaru OEM Serpentine Alternator Belt for 2022+ WRX (23780AA070) cheapest?
At STM Tuned Inc., for $36.93, as of our latest check.
