i've got a water leak on my 555 and i can't find where it's coming from? if i drive fast it pressurises and comes out the coolant down the sidelight and if i take it easy it don't leak. have left it on my drive for 2 weeks now and its lost over a litre of water. i don't know what to start changing as i'm still hoping its not the headgasket

have you checked your radiator and pipes?

scoobysteve2286

i've had a look but can't see any water coming out... is starting to drive me mad as i can't give my car a good thrashing

DEANO1988

you might not see any water comin out until you've started it or after you've driven it a few miles

scoobysteve2286

do you think i should jack the front up and leave it running for 10 mins and have a good look underneath?

it would be good to see if anyone else has had similar problems

Take off the top and bottom rad hoses and give them a check as they are a common problem.
Also check to see if there is any white sludge under the oil cap that would indicate that the head gasket has gone

checked the oil cap and theres nothing to suggest to me that the headgasket has gone so fingers crossed with that one still...

what should i be looking at with the radiator hoses exactly?

DEANO1988

i had a water leak, i had a slight crack on the side of the rad, its worth a try

loose/cracks/splits etc

scoobysteve2286

i can't see anything though... think i'm gonna need a head pressure test. took it for a quick blast down the road and even though the radiator wasnt topped up it still pressurized quite a bit and the car struggles for power after 4.5k revs

mine done exactly the same feel the passenger carpet is it wet?u don t really get water in the oil with hg probs

you dont get mayonnaise on the oil filler, its a flat 4.
Its the rad hose, which side is it leaking from?
its a pressurised coolant system so when hot the pipes are expanding and squirting coolant out.

i dont no if this will help http://www.subaru-impreza.org/forum/...-symptoms.html

i don't know where the water is leaking from... only that when it pressurizes it comes out the blow off down by the o/s sidelight.. would a dodgy rad hose cause performance problems though?

and sonic... what do you mean about a wet passenger carpet?

Peanuts

iTrader: (15)

Sonic is saying that you dont get mayonnaise on the filler cap with a flat 4 that has done its head gasket.
You get water in the passenger footwell, check the carpet, is it wet?

Peanuts

what do you mean, out the blow off down by the o/s light..?

What do you call the blow off?

sonic93

iTrader: (16)

mine did same it comes out just by bat when under boost done hg dye test and it was very minor but was on way out.it normally blows at the matrix to thats why i ask bout passenger carpet mate

scoobysteve2286

the black house thats attached to the coolant by the battery mate. i only call it a blow off as its similar to a blow off pipe we have to fit on refrigeration systems at work

Peanuts

iTrader: (15)

battery is nearside, you still drive on the left in Coventry?
That pipe is coolant overflow, basically the system is over pressurising and getting by the rad cap which in turn over flows to the filler pipe at the nearside of the rad and then ditches via a pipe into the chassis leg..


Your car is ****ed, sell it and buy a different one

not a radpipe sorry.
looks like worse

scoobysteve2286

surely the prob isnt that bad... what do i need to do?

i don't want to sell it...

scoobysteve2286

anybody?

Sounds like head gasket to me. Dill had it on his type R and it was pushing water out of that overflow on track. Further investigation proved it was head gasket and it had to be changed.

yea hg mate mine did it and it was very slightly gone mate so doing hg now on mine just get it fixed

Steve, I looked at your car weeks ago, and told you I believed the HG had gone.

It pumps water out of the overflow tank, has bubbles in the overflow tank (lots of) and the overflow tank even smells like combustion gas.

I do realise you dont want to here this mate, but there is no way around the fact.

Take it to Mark and have a second opinion from a Subaru tuner at least you will know what direction to go in regards a cure.
