Why is your 1991 Mitsubishi Montero leaking water on top off the transmission?

OK I just went through this myself with my 94 Montero LS 3.0 and at first I thought it was the transmission leaking because it was picking up some residual tranny oil and it was reddish in colour however when it started to turn green I was perplexed... I traced it, which was difficult to do because of the proximity of the firewall to the back of the motor and I found it was coming from behind the motor and below the intake manifold in a cavity through which a coolant transfer tube runs into the back of the water pump(which is mounted on the front of the motor behind the timing chain). "Hint" I also observed that when the car was slightly slanted toward the front the coolant would run out from below the crankshaft pulley in front of the motor. This transfer tube water pump connection had a failing o-ring and after I took off the water pump I noticed some rust around the bottom of the pump seating surface sooo it could have been leaking there also. Anyway the water ran through the cavity out the back of the motor and ran over the top of the transmission.
Hope this helps

It is most likely that a frost plug has "popped" or is leaking. I had something similar happen to my Montero Ltd. The supply line to the rear heat vent had a leak and was causing the radiator to drain quickly.
