I knew I had coolant going somewhere and I found it in the passenger foot well, draining into the right outboard foot well channel.. damn, damn, damn.. I've got the carpet up and pulled out and threw away the wet filthy underlay.. they used some fantastic glue to hold that down, lol. So where should I start looking, thanks billy, and yes, I'm attempting to use the search function, and I read somewhere that eliminating the rear heater was a good idea, so?
