Blown head gasket or cracked head.
Possible that coolant is leaking into combustion chamber and burning off. Does engine act like its missing at idle and smooths out at higher rpms? possible head gasket. I had the same problem i used steelseal.com worth its weight in gold.
A leak.
some general causes: leak in cooling system (including possible blown head gasket) resulting in loss of coolant; defective thermostat
many possible causes, low coolant, worn out coolant, bad thermostat, no circulation (water pump) radiator blockage, pressure loss somewhere
It is possible that the gasket could leak between cylinders. The overheating and coolant loss would happen if the gasket was failing around the coolant passages.
Engine fail safe is on the 4.6 L V8 engine only - ( you have lost your coolant ! ) - find and then repair the cause of your coolant loss
Diagnostic Trouble Code (DTC) P1299 indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Failsafe Cooling was activated to cool the engine. (Refer to Section 1A, «Electronic Engine Control (EC) System», for more information on Failsafe Cooling Strategy and the cylinder head temperature sensor.) Possible causes: -- Engine cooling system concerns. -- Base engine concerns. -- Low engine coolant level or loss of coolant.
White smoke from the exhaust especially at startup. Coolant mixed with the oil. A white foamy substance on the underside of the oil fill cap. Loss of coolant with no apparent leak. Engine overheating with possible miss.
If by water you mean engine coolant, yes. Loss of coolant, antifreeze, is a major cause of overheating.

Loss of coolant with no apparent leak, white smoke from the exhaust, overfull oil level, a white foamy substance on the underside of the oil fill cap, engine overheating, and possible engine miss.
Yes. It doubles as an expansion tank for the coolant. Without it the system would be total loss and you really don;t want to run out of coolant on that engine.
