1994 Subaru WRX STi Version 1 Radiator

JoeAlcohol · 11-06-2022, 07:53 AM

I recently replaced the front bumper on my 94 WRX STi. When I lifted car up and pulled off the front right fender liner I noticed some coolant leaking from the front right corner of the radiator. I did some digging and didn't see any breaks but did notice this plug without a hose attached. Is this a transmission oil inlet that isn't attached because it's a manual or should there be something attached?

Radiator petcock to drain.

The way the radiator in the early cars is assembled the leak could be traveling along the metal covers on each end. It might not be coming from that drain petcock.

You're right. It's not coming from there. It seems like it's coming from the corner of the radiator and only when I have the front up on jack stands. I re-installed the front bumper and lowered it back down and no matter how hard I drive it there has not been another leak. The coolant levels are still good so I'm going to leave it for now while I finish the body work and then address it with a new radiator once I'm done.

Thanks for the feedback. Everything on this car leaves me second guessing myself.
