So i recently replaced my water pump on my 2001 gs300 i had to remove the radiator and after i put it all back together i noticed there is a clear drain hose that sticks out of the bottom that is leaking all my coolant. Im sure i put the drain plug back in correctly so i dont know what could be causing it. I found this picture on another thread but its perfect to try to better show the hose im talking about. I believe the drain plug/drain **** is supposed to stop it from leaking out of this hose so does anyone know why its still leaking out??? Please help

Silly question, but have you tried turning the valve to make sure it isn't loose? If it is, then that would explain why the drain is leaking.

Also, that valve or drain plug have a O ring. Maybe the O ring is old broken inside or worn. Put a new drain plug or O ring. The transmissions shops have a lot of these O rings and the auto part as well. Is another idea to check your drain plug.

Mcon you were right on the money. I replaced the tiny o-ring on the drain plug and it stopped! I cant believe that little piece of rubber could cause such a headache! Thanks
