#7228 of 8657 Re: Water sloshing in roof 2001 Outback VDC [toofastdad]
Sep 21, 2007 (6:52 am)
I had the same experience on my 2000 Outback Ltd. - I hope my findings are not yours....water sloshing when I first startup and drive was ultimately an internally leaking head gasket, please let me explain....
Coolant leaks through head gasket (primarily at cyl. 4)
Air from cylinder exchanges and becomes trapped at highest point in heater core.
When you first drive the vehicle T-stat opens and forces coolant through the heater core causing a cavitation sound that you just know is water on the roof (I know this is bizarre)
This is the QUICK CHECK, with engine cool, radiator cap off, start the engine and let it warm to operating temperature, when it heats up enough, the Thermostat will open, if it is this head gasket you will see air bubbles one after the other come the surface.
This is another QUICK CHECK, pull the cap off of the coolant overflow container when HOT and watch for air bubbles coming from the tube in bottom.
This problem gets worse.....Check Engine light will eventually show a misfire because when your parked the cylinder fills with coolant, rough idle for a few seconds just after start - or O2 sensor failure because this misfire causes o2 levels to become out of spec.
please let me know if your problem is resolved..
Again, I hope this is not it, but if you would like to know how that I went Round and Round with Subaru and this problem Email mglobnahotmail.com

"The drains aren't in the rear bumper. They would be behind the front wheels. The drains generally go down the A-pillar forward."
The sunroof gutter has a drain tube at each corner. The rear corner drain tubes go the the rear. If water is heard sloshing in the sunroof system when the car first moves after a heavy rain, it would be water in the gutter. The fact that the water has not entered the interior, and has been seen dripping from under the rear of the car, indicates that the water has gone down at least the rear tubes, and no doubt the front tubes, too.

I'm interested in how you made out getting the head gasket repaired. My 2001 Outback is in the shop now for the same problem. I'm wondering if now's the time to look for another car, or if this will be the worst of it. Once a mecahnic drops an engine, it's usually all down hill from there.

The head gaskets on my 2001 Legacy were changed in Feb 2006 at ~110k miles. It's been fine since.
I still liked the car and it's cheaper to repair than to pay 10x more for a new car.
Even though I've had more problems with my Subie than other cars, Subaru would still be high on my list when replacement time comes.
#7233 of 8657 Water Rushing sounds...
Sep 22, 2007 (7:26 pm)
The last week or so in my 2005 Outback 3.0, I've heard 'water rushing' sounds coming from somewhere up front. Almost as if water is rushing & sloshing on the other side of the steering wheel. I don't know if it's coincidence or not, but I hear it more when I turn the wheel to pull out of my parking space. However several minutes into my morning commute, it's gone.
Does this sound like a serious issue? Other than that, there is nothing wrong that I can tell.

Check your coolant a lot of times I have heard this in vehicals with low coolant. Its from air getting into the heater core I believe.

I have not had head gasket issues yet (knock on wood)but saw the dealer put some of this additive in a subaru and the stopped leaking almost immeadatly. I probably would have never believed it being a heavy truck mechanic my self had I not seen it with my oun eyes. I would see if someone would ship you some from the states. Or buy some over the internet.

Yep, that is exactly what plim77 is hearing. Likely not an issue, but it does indicate there is air in the system. Top off your coolant in the radiator and fill to the proper level in the overflow tank, then wait a couple days to see if this takes care of it.

Also you might want to have your system drained/filled/flushed if it has 50k miles or more.
