So I have a 2013 bone stock wrx hatch. I just noticed yesterday that I am low on coolant. Oil is not milky so I don't believe it's a gasket and only get steam out of the exhaust on cold days. I am taking it to the dealer tonight seeing that it is still under warranty. My question is do you guys have any suggestions on where else I should look for a leak? Oh yea and there is no sign of a leak in my garage where it is kept. Any suggestion would be helpful.
