went out today! steam started comin out of bonnet vents! the car didnt over heat! but had used all the water from the header tank! and also water lying on the head near the turbo! split or burst water pipe?? any common probs with these years?? 1993 import wrx, 80,000 miles, cheers! Craig....

 

Turbo return water pipe that goes to the top of the header tank.
At the connection where it joins the header tank, the plastic elbow on the header tank turns to paper mashee type mush........

You may find, as soon as you touch the hose that end it falls off.....

 

Also check the end plates on the radiator (drivers side) these can have hairline cracks and under pressure spray water absolutely everywhere!! The top hose is also prone to splitting and like Scott says the connectors on top of the header tanks are very weak, be careful around them.

 

cheers guy's, just gettin my jacket on now! it's freezin out but she needs fixed so gona go and start ripping thing off lol!! hopfully find the prob!

 

best bet, refill it, then with engine running and car upto temp and heater blowing warm in the car, squeeze the top hose (be very very very very careful WHEN DOING THIS THOUGH AS OBVIOUSLY HOT WATER SCALDS) This will probably help you to locate the source of the leak.

 

iv can see the genral area of the leak!! need to remove pipes between air box and intake! to get in better! just to many pipes in the way to see exactly where its leakin from! i can also feel the main top pipe from the rad startin to split wen pressure applied1 but not right thru yet!
