here is the engine coolant drain cock of 1993 Camry Exec 2.2?

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

It should be on the backside of the radiator on the driver's side, near the bottom and toward the outside. It will look like the head of a black plastic thumbscrew. There is usually a little tube underneath the screw on which you can put a large piece of vacuum tubing to direct flow of the coolant into a container. This step is not absolutely necessary but can help eliminate some spillage which usually occurs.

If you look carefully you can see the radiator drain from above. Reach in and open. Hand tight is enough. Should be able to loosen without tools.
If you want maximum life, use only Toyota red coolant mixed with distilled water.

Thanks mate! One of my colleague suggested me fill some water in , not necessary fill coolant in. is it true?

You still need to use coolant, a 50-50 mix of antifreeze and water to keep things lubricated, like the water pump, and to keep other things from rusting inside the cooling system. If you were going to add water for a day or so, until you can do the coolant change go ahead, but I wouldn't leave straight water in there any longer than that.
