For the last few weeks, I started loosing about 4 ounces of antifreeze a week.

I was able to smell it but not see it. Today, I put my hand below the thermostat housing and felt that it was a bit wet. I still can't see the leak, as I can't see the bottom of the thermostat housing without raising the car, so for now I am assuming that it is the gasket.

Is it common to have a spontaneous thermostat gasket leak? Did any ever experience such a leak?

My Thermostat was installed about 2 years ago, and has never leaked until now.

Thanks
