Extremely interesting thread. I have smelled coolant in the car for a few months, and in the last week I've been seeing coolant drip from the right rear wheelwell. I figured it was time for a new coolant tank. But I decided to take Krieger's lead and make sure that I don't just have a bad cap. Here is a pic of what I found, dried coolant coming out from under the bleed valve. So what do I do about this? Is there a gasket under the bleed valve that can be replaced?
