Just a thought, Change the rad cap!!

If the seal has rolled it won't hold pressure and that will alow the coolent to boil.

Had this problem when I first got the car afer it was serviced.

Hope you get it sorted soon

I would suggest you get a hydrocarbon test done on the coolant.

It is, almost always, a head gasket problem.

 

Pete

it hade the head gaskets done only 6000 miles ago could it still be them?


Iain
i have change the cap ( to make sure i used the cap from my other scooby the same year ect)

 

Could be. It needs testing. Were the heads skimmed? If so by how much?

 

Pete
the heads where not skimed (afaik) a sticking valve when i bought the car was the reason the gaskets where done as the garadge that i bought it from sent the car to a impreza specilist to have the work done (some place just south on Newcastle) he had all the valves replaced for me so that there would not be any truble like that again they allso done the timeing belt service FOC ,

sorry to bring DOWN the tecnical level of this post but when you say it keeps boiling over where from? currently I have a Water headertank that keeps pi$$ing water out the side I thought it was just the tank that was the problem and am in the process of replacing this please tell me I havent got head gaskets to look at as well :-(

They also air lock very easy. Be sure that the system is completely filled with water.

 

yeh it is pi##ing out from the header tank round the top rim and from the hose at the bottom rear of the tank but no place els.

I have a Legacy Turbo that is doing the same. It keeps on weeping form the seal at the top of the header tank.
Is the header tank in 2 parts? Is there a seal around the top of the tank? Or is it split?

 

The early plastic tanks, are also just plain ****. They leak/break all the time. Ther are just made of the crappest type of plastic known to man

 

I ordered a Forge alloy tank for my MY93 jap WRX and when I got it the lower mount was in the wrong place

I spoke to forge they advised me that they thought this should fit all early imprezas no problem got my money back but still have no header tank

I am reluctant to repace with an O.E. item as they obviously have a reputation any sugestions
