Question Subaru Forester 2010 Coolant Leak

Hi All,

I recently purchased a Subaru Forester 2010. I have been quite happy with it so far.

However, I am noticing that the coolant level in the reservoir has been dropping slowly, but steadily.

I have taken a picture of the reservoir and the black metal plate underneath it, which has some stains. I just noticed the stains today. I did not smell the coolant though.

I have two questions:
1. Does this look like a coolant leak to you? (I am taking this to the dealer soon anyway)
2. Has anyone else had such a problem with their Forester as well?

I have my 10'XT for a year now, nothing I notice. Just make an appointment with the dealer. If that is a leak it should cover by warranty.

The coolant level should be at the low mark when cold and high mark when hot. Look at it first thing in the morning when it is cold, and it will probably be at the same low level every day.

The dried white stains look like water spots from road spray on the shiny new black frame paint. Such dry white spots don't look like the continually wet seepage of a coolant leak, Nor is the the overflow tank a likely place for a leak.

I think he is talking those large green/blue residue underneath the timing belt cover. I'm guessing waterpump area, maybe the wp seal.

I can't see a green/blue residue under the reservoir, but the picture is not so good. And under the timing belt cover I only see the pavement with a leaf on it.

He has a brand new car, so it's not likely the water pump is leaking. Even if it was, would its leak be in this picture?

I have had to add a few ounces of coolant to my 2009 over the last year. I attributed it to evaporation due to driving in extreme heat. (Las Vegas, Death Valley, at 110+).

The "bottle" is there for expansion and contraction of the coolant as the temperature of the system changes.

Not sure about the picture. I would clean the area and then watch.

OK I couldn't tell if it was the pavement or what.

Clean off the "stained" area, tape some white paper over that area, and see what color the new stain is. Much easier to discern the color of the fluid that way.
