    I bought this radiator back in 2012 and unfortunately it arrived with shipping damage. Fortunately I was dealing with RSD and I had a new radiator almost before I had the damaged unit back in the box. During the last four years, I've had the radiator out of the a couple of times, earlier this week when i had it out to replace a leaking cam seal, I noticed that the petcock would not tighten back up. The plastic threads in the radiator are about gone. I'm done with plastic radiators, this one was number three not counting the one I sent back.

    Replacement for Manual Transmission 9 years ago

    I bought this to replace my rad in a stick shift. Fitment was exactly the same and the automatic lines did not interfere at all. Great product and great customer support.

    Works great for 2002 WRX's - Both Automatic AND Manual Transmissions 10 years ago
    5out of 5stars

    I was in a pinch the other day. The Radiator in my 2002 5-Speed Manual WRX decided to randomly spring a leak. I searched for anyone that had one in stock. RSD to the Rescue! Apparently Koyo doesn't make a specific radiator for the 2002 5MT WRX. I guess you can do some rigging and get the 03-07 radiator to work, but that didn't look fun. So, I figured I'd take a chance and see if this one would work. I just left the lines at the bottom capped. Everything went awesome, lined right up, slid right in and bolted up.
