While driving into work the other day my legacy overheated. Immediately pulled into parking lot and shut car off. Opened hood and noticed coolant around passenger side front of car, where hose connects to radiator. Later pulled radiator hose off to inspect and found hole. Replaced hose and coolant. Drove into work today, opened hood and coolant once again sprayed around under the hood, on the passenger side front of car. Apparently, must have caused hole in first radiator hose when I removed it.

I noticed on the far passenger side of the radiator down 3 or so inches is a hole/indentation with a small rectangular piece portruding from the center of it. Could this be some kind of a pressure relief mechanism? Your thoughts on this dilemma appreciated. Thanks.

When the car is sitting at idle does it loose coolant? Sounds more like a cracked radiator to me. Try to get underneath and inspect, in my opinion and eperience when Subies overheat the radiator cracks fairly easily under a fair amount of pressure.

The plastic end tanks crack in the front. It's pretty common. You're going to need a new radiator.

Have been checking under the hood several times daily to look for leaks.

I thought the problem was solved with the new radiator hose. I purposely waited several days before readding antifreeze to make sure all was well. I was fooled!

After remaining leak tight for the past 4 or 5 days, coolant was once again sprayed around the engine bay area behind the passenger side headlight. The problem is I can't seem to get it to spit while I'm watching.

Before driving to lunch today, rinsed everything off again. Checked under the hood at eatery and after arriving back at work - no leakage. Probably is the radiator, but I'm not dropping the money until confirmed.

Read my post above!

 

Rent or buy a pressure tester to pressurize the system. You will more then likely see it leaking right where I said.

You guys are right. Radiator is leaking from the front. Can this be patched with, say, fiberglass and epoxy resin or is replacement a necessity?

Can't help it; I'm a cheap bastard.

I believe others have tried to patch it, but it doesn't work.

 

Just get another radiator.
