About the apparent leak. It's pretty-well described by this article, should anybody else observe the same issue:http://www.justanswer.com/car/1dj2v-mitsubishi-eclipse-non-turbo-420a-leaking-coolant-engine.htmlHTH.P.S. What's the purpose of the water pump weep hole and what would cause coolant to leak there?
