Default Radiator leak

I noticed my radiator is leaking :-( Seems to be coming out at the top where the aluminum is crimped to the upper plastic. The car is an '02 with 55Kmi. Since it is out of warranty should I get a Subaru OEM replacement or are there better aftermarket brands to consider. One would think that a radiator should last at least 100K in this day and age.

Anything with plastic endtanks will least likely last to 100K

Hmmmm....I have almost 7 years and 134,000 miles and no radiator leaks.

HG's, yes.
Crank seals?, yes.
Water pump?, yes.

Since I have never replaced it, I don't know of a good replacement.

Ok, then Charlie has the special radiator. 100K does seem wrong doesn't it?

Simply said, plastic endtanks have to deal with deformation (whenever plastic or elastic) under normal use, they can come apart or no longer hold a good seal. Either that or the plastic endtank (even if they're treated for heat) will over time become brittle or weakened to a point where crimps no long hold the tank to it's sealing surface well.

For a temporary fix, you can try putting some JB weld on it, but don't expect it to last longer than a month or so.

If you have not done it already take the car in for the radiator conditioner recall before you spring for a new radiator. It might save you a bunch of bucks.

There is no coolant conditioner recall for the WRX and head gasket leaks (which the conditioner is designed to prevent) are rare on the WRX.

What isn't so rare on a 2002 WRX is a radiator leak from a seam at the top. The replacement part for it has been redesigned and has its own filler cap. I've not seen any problems reported with Subaru's redesigned unit.

can you describe what causes the problem and if the car will likely overheat if driven a few hundred miles in that condition?
