Recently I picked up an '89 190e 2.6, 5spd and the other day I discovered a coolant leak right above my transmission, my mecanic said it's the heater core and gave a small heart attack on how much it woul take to fix, anyways I got ready to rip the dash out untill I came across this site, about a year ago someone mentioned an inlet heater valve that was causing the same problem that I am experiencing, would anybody be able to tell me where this valve is located and how to get to it. Thank you.
