hi i have a 1994 wrx and i have noticed coolant leaking from a pipe on the secondry header tank but only after driving hard then park car up go back 10 min later and there is quite a bit of water on floor.
is this anything to worrie about or am i just over filling it?

 

secondary header tank ? ? ? ? ?
in front of the battery ? if it is then that's the overflow .

if it's THE header tank (right of air-box) then get that sorted ASAP . . .

 

hi the one in front of battery has a over flow pipe on top thats where the water is leaking from.
