Mom has a 2000 Camry she bought back in 99. I think it has about 145K miles. Yesterday in a parking lot she is driving and it "clicked like when you have dead battery and died" Pool of coolant under car. A guy came by and helped her push it out of way where it has sat for about 15 hours. I go to look at it today and see coolant on ground but radiator and front area are all clean and dry. Her oil was full and clean with no emulsion. Looks like it leaked from bottom/front of engine? I dont know much about those cars but you think it would be the water pump? Any thoughts? Thanks.
