If no liquid in the cooling system, then the heads are probably warped and the engine is ruined. If running straight water and no antifreeze, then permanent damage unlikely unless the temps have been cold enough to freeze the water in the engine (popping the freeze plugs), or the engine has gotten hot enough to boil off the water in the cooling system. 50/50 mix of distilled water and antifreeze is necessary to prevent freezing, boil-over, and cooling system corrosion.
The Green AntiFreeze is the answer to this question. The only Toyota's that takes the Pink AntiFreeze are the 2006 and newer.
You have to go to Toyota and get the coolant that Toyota makes for their vehicles, DO NOT add GM Dexcool antifreeze, it is not the same.
A 1999 Toyota Camry does not require a specific antifreeze. Any brand name or non brand name antifreeze can be used in the 1999 Camry.

A 1992 Toyota Corolla can take any type of standard antifreeze. It should be labeled as being suitable for all makes and models of cars.
One type of antifreeze that can be used is Pentosin PENTOFROST A1. Pentofrost A1 is an antifreeze for Asian vehicles in water-cooled engines.
1998 Toyota Camry takes red antifreeze. some take green and orange, depending on the year. was never given a name, just the color.
possibly a head gasket is cracked
