    Good Evening,

    I have a 2007 Forester (non-Turbo), Auto, and the Radiator just gave up the ghost. I’m looking for an aluminum replacement, and I think this is it (#2874). I’ll be running an Oil Cooler separately for the ATF.

    Can I purchase directly from you guys? Also, do you have available inventory?


    Hi Dane,

    The OE Subaru interchange part number for the CSF #2874 is 45199FC031 which fits the 93-98 Imprezza and 96-98 Outback. The 07 Forester uses Subaru Part Number 45119SA060 which we do not have an All-Aluminum option for. The tank and core sizes on these two radiators is different but if you’ve found information that you can interchange them you’re welcome to try but we cannot guarantee fitment.

    We do not sell directly and we currently do not have any stock on them. We don’t have a way to check stock with all of our dealers so it’s possible someone has one in stock. However, our main distributors do not currently have any in stock.
