I drive a 2002 wrx. I got some sealant stuff cuz my radiator was leaking. The directions say to remove the radiator cap and pour in the solution. I couldnt find a damn radiator cap? Does the 2002 wrx not have 1, or am i just an idiot? Is there anywhere else that I can put the solution because I really want to fix this asap.

Thanks again guys,

Bryan

For the 2002 WRX, the radiator cap is located near the intake manifold. Basically right above the intake.

What "sealant stuff" did you get? It really isn't a good idea to use products such as Stop Leak to try and fix a leaky radiator since it may eventually clog the small passages in the cooling system. If this is the official Subaru conditioner it may not do that but it probably won't fix your leak either, it isn't intended for that purpose.
Your best bet is to get a new radiator rather than try fixing the old one on the cheap, it may just cost you more later. This is also a good opportunity to upgrade to the later style radiator which does have a cap on it, those are less prone to leakage and also the second cap makes cooling system service much easier (less trapped air when refilling).

Mulder is 100% spot on. Back in the old iron block days....Bars Stop Leak or a little egg whites dribbled into your coolant was the money. Nowadays....not so much.
