    Leaking Coolant / Fluid - PLEASE HELP

    Just purchased my first impreza 2 days ago, a 1998 sti version 5 type-r.

    When got home and parked it up I noticed it was dripping coolant/water. But I had driven in 50miles and no problem.

    It seems now that it does not do it all the time, just sometimes. But drives fine and the temperature/thermostat is bang where it should be.

    On close inspection the dropping is coming from the front left of the engine (thought originally was intercooler water) where there is a black round cylinder next to the radiator, I still cannot see where exactly the leak is coming from as itís inconsistent.

    From this black round cylinder there is a hose that is about 5Ē long thatís not connected to anything, is this an overflow??? And theres nothing to worry about??


    Any help I would be very very grateful

    Thanks

    think the leak is coming from the bottom left of the radiator as you look at it, not 100% though. but all that area is very wet.

    where the radiator mounts, you can see through the front bumper is wet on the mount, then very wet as i look from underneath. but can see splash marks quite far up the engine bay.

    doing my head in, my first impreza and only had it a few days


    ALSO, how should i top up the coolant? just simply fill up the bottle behind the passenger headlight to the `F` ?? sorry for being a dumbass!

    If you can post pictures that would be helpful. Keep it topped off as you described. Also, avoid "driver" and "passenger" descriptions as these vary geographically; my car is reversed, for example.

    From your description I can't tell what the black round object might be. Pics would help a lot. I'd keep the car parked until you sort it out.

    Its a process of illumination unfortunately, that's if you do not feel like taking it to the dealer to have it checked out.

    First thing I to do is familiarize yourself with the way the cooling system works.

    1. make sure all the pipes are connected correctly (i think this might be it, seen it happen to a friend before)

    2. It might be overfull of coolant, so make sure its at the correct level in the filler bottle (tip - NEVER open the heater tank cap when the car has been driven or idling, if you do the water blows out and air goes in... you will spend weeks trying to get all the bubbles out!)

    3. very important and you need to have this checked very soon upon purchasing the car, get the car tested for blown head gasket. Its a chemical tester they put on the heater tank nek to see if there is any co2 in the coolant.

    Where you from and where did you buy the car off?

    how do i top up the coolant???

    simply pour coolant into the thin bottle with the yellow cap behind the headlight, to the`F` ???

    just getting told to top up the header tank? but how do you know when it is full as it is alloy?

    sorry again for being a dumbass!

    Dude ignore my last post this is where the problem lies. Ok dont ignore it because its good advise for future reference...ghehe!

    This hose you see needs to go into the filler tank this hose comes from your heater tank and when the car is at a certain temp (cant remember now think its 85c) the heater tank cap opens up and pushes some water out that goes through the over flow pipe and into the filler tank... as the car cools down it needs that water and retracts it. so if its not over heating now its going to suck air and do overheat!

    Correct!

    Open it when the car is cold, peek inside if it needs coolant you may put some in! Your will prob never have to open it!

    sorry again for being a dumbass!
    I didnt ask and blew a head gasket on my 02 sti, still paying for it!

    Just follow the hoses coming out of the heater tank, one at the back goes to the turbo, other two goes to the front of the car one stops at the radiator and the other should be the lose one you talking about that needs to go to the filler bottle...

    so the header tanks needs to be full to the brim?
    Yes

    and then top up the coolant at the thin bottle with yellow cap to the `F` mark???
    yes

    is this correct?
    yes



    another tip... and this is after you sorted out the leak... keep in mind that you need the right combination of water and antifreeze in your cooling-system(of your car)
