DROVE APPROX. SIX MILES FROM HOME TO CHRISTMAS EVE. CHURCH SERVICE WITH FAMILY. WHEN ARRIVED, STEAM AND SMOKE WERE COMING FROM FRONT GRILLE, AND AROUND ENGINE HOOD. THOUGHT THE CAR WAS GOING TO START ON FIRE. ALSO MAKING A HISSING AND GURGLING NOISE. WAS QUITE AN "EVENT" IN THE PARKING LOT! HAD INSPECTED TWO DAYS LATER (AFTER CHRISTMAS) AND FOUND FRONT INTAKE MANIFOLD (PLASTIC?) PASSAGE CRACKED AND LEAKING ENGINE COOLANT ONTO TOP OF ENGINE BLOCK. ALSO COOLING FAN WAS BLOWING LEAKING COOLANT OVER THE PASSENGER SIDE, ENTIRE TOP OF ENGINE. NO COOLANT LEFT IN COOLANT RESERVOIR AND NO COOLANT FLOW THROUGH ENGINE; DUE TO AIR BUBBLE / LOSS OF VACUUM? I NOW HEAR MERCURY HAS A "SECRET RECALL" ADMITTING THIS IS A COMMON FAILURE AND REPAIRING VEHICLES LESS THAN SEVER YEARS OLD FOR FREE, ALSO HAVE READ THAT "FLEET" VEHICLES ARE BEING REPAIRED FOR FREE, BUT DENYING OWNER ASSISTANCE TO SAME VEHICLE, ENGINE AND INTAKE MANIFOLD TYPE TO "OLDER" MODELS. *NM
