    Coolant leak drivers turbo

    Guest-only advertisement. Register or Log In now!
    Hey Iíve had a slow coolant leak for sometime thatís now evident on the drivers turbo. Any way to get at this without a motor pull? Not sure if itís the feed or drain (or whatís more common) any thoughts would be great!

    Topped the water off, ran it again... no leak when parked like before. Itís a steady leak though at least before this going through 2 gallons of distilled water every week. I thought it had just gotten worse.

    I think @fleener22 had a leak from one of his turbos and he managed to fix it without removing the engine. Check out post 277 in his simple and clean K04 build thread. Youíll just have to figure out which line is leaking and then see if you can make a tool for it.

    Ok thanks! Iím going to try and rent of those pressure testers somewhere that goes on the expansion tank. Iíll start removing stuff from the top to see if I can get a eyeball on things a little better.

    Are you sure it's the turbo? The fact it doesn't do it every time leads me to think it could be something else, for example the afterrun coolant pump under the intake manifold. Look under your intake manifold and y-pipe and see if there's any coolant pooled in there.

    Iím not sure myself. Thatís why I need one of those coolant system pressurizer testers. I say the turbo because a shop mentioned it when they topped me off with coolant last winter... when it was very slow. It also manifests itself under the drivers turbo there more or less when it was dripping out visibly like in the video. Since then it hasnít done as much as this but back to setting off the sensor after a few short trips.

    The pump sounds normal when itís running, but this is a possibility Iíll check under there again sometime. Iím running distilled water so itís hard to see more or less and evaporates pretty quickly Iím guessing why itís hard to see - hot engine, summer time.

    I did get some good info from that thread. Tool would look like this:

    Turn the car on, jump under it and see where itís leaking from. If you had coolant in it you could see the crust in the banjos, but since you donít, youíll have to look for it dripping.

    Well itís gotten progressively worse, itís needing to top off the reservoir every 15 minutes or so of run time. Iím sure jacking it up and having it run it should be easy to figure it out.

    However, from the vid when it really spewed out there off, itís tough to see in that area. Lots of potential spots and pretty tight. Itís definitely more or less when itís running or overheating/boiling over while turned off sitting.

    It tends to steam up from the heatecore Iím guessing I hear a gurgling and boiling behind the dash and fog up the inside of the windshield when itís boiling over when level is low and driven on, my secondary power fan doesnít work as well. I get it off before it goes a notch or two, but still just water no coolant.

    Shop said it was the turbo coolant line a while back when it was very slow and motor pull was required. This was winter time and I had coolant in there, so maybe they just saw the crustiness. Iím sure I just need to make a tool by grinding down a cheap 19mm wrench and get after it. Def wanna rule other spots out first though.

    Thereís only so many places it can leak back there. Crossover pipe, heater core hoses, turbos, after run pump. All of which can be seen with a flashlight without removing anything.

    Gotcha, I peaked under the intake manifold galleys there while parked, and def has a leak there. Iíll double check while itís running tomorrow and jack it up from underneath. IMG_3277.jpg IMG_3278.jpg
