Coolant leak


#1

I have a 2005 subaru impreza RS with 99000km. the coolant in the overflow tank is turning into a shaving cream like substance, and it foams up and leaks on the ground. I took the car to the dealer and they say they have never seen this before. please help!


#2

My bet is a blown head gasket.


#3

I second that motion. Do we have a third? Make it so! They should be able to tell that pretty easily. There are numerous ways to test for gasket failure.


#4

Is it possible that someone mistakenly put windshield washer fluid or some other sudsy fluid into the radiator or overflow reservoir?


#5

The dealer suggested that could be the problem but that is highly unlikley. I am the only person that touches my car and I would not do that. I also only take the car to the dealer for service and a doubt they would do that either.

Have someone, or you, check the engine thermostat for an intermittent sticking situation. Also check the radiator hoses for a collapsing situation. Check the water pump for proper operation. While engine is cold, carefully open the radiator cap. Start engine. Rev up a little. See if coolant mixture is circulating. Before you start the engine, use a coolant test “baster”-type checker to determine if your anti-freeze/coolant mixture is still good. If one or more thing shows up as defective or marginal, replacing any one or all of these is much more cost-effective and less time consuming than changing a head gasket. A pressure check of your cooling system might be the first thing that I’d do.

Thanks alot for everyones help. My car is still at the dealer so I can’t check it. I took it to them because my overflow was empty, they did a pressure test, said nothing was wrong and sent me home. The next day I found coolant on my garage floor so I took the car back. This was two days ago and they still don’t know what it is and I’m car-less. Maybe because I’m 500km shy of the 100000km warrenty they don’t to fix it.

When a warranty item is presented to the dealer BEFORE the warranty expiration, and it’s unresolved AFTER the warranty period, it’s STILL covered by that warranty.
They may have done a cooling system pressure test; but, probably, didn’t pressure test the radiator cap. The simplest "test"of the radiator cap is to just change it.


#9

Now they are telling me that the heads are warped and that the engine must have over-heated. I am the only per who has ever driven my car and I know it has never ever run hot. I do my own oil changes but I do not keep the reciepts. Will they still honor the warranty? I don’t think an oil problem could even cause this type of damage.

Third. With emphasis.

I have seen this before. Blown head gasket.
