We took the sti3 on another trackday at donnington but as soon as my bro got home all the rad water leaked all over the road.

He filled it back up after 10 min but the water never leaked back out any ideas chaps ?

R.B

 

It could have overheated and boiled over...where coolant would escape through the overflow.

Keep a close eye on it, or take to a garage for a pressure check (just incase it is leaking).

If it was overheating, you need to find out why - check the cooling fan would be a place to start (put ECU into test mode - both plugs under the dash and switch on the ignition).

Sounds like you either have a weak filler cap spring or ... a head gasket gone.

Quite possibly.... Like my STI3

 

DOH If it is where can i get a group n or a stronger one from ?

 

Or my Sti v3 after hill climb, the gasses from the cylinder blows ALL the coolant out. Usually all down the nearside front.
Getting stronger parts? I have kept with the stock Sti parts, but you could try Roger Clark Motorsport for the Group N parts, or TEG Sport?
