Does any expert give me any ideas where is drain cock? My car is 1993 Toyota Camry Exec Sedan 2.2. Unfortunately, I bought this car without manul last month. I found the level of engine coolant too low than "low" line although no overheating warning. I am going to change coolant, but I cannot find the drain cock. If anyone send me some guide, it will be much appreciated. By the way, what kind of coolant should be filled? My friend gave me green one, I am not sure whether it is OK or must use Toyota own coolant. Thanks in advance.

Why don't you try the Camry (http://www.automotiveforums.com/vbulletin/forumdisplay.php?f=441) forum?
