The drain **** is on the lower right "backside" of the radiator. You can't get to this or the lower hose without removing the plastic shroud under the radiator. This has 5 bolts holding this on. Then reach around the back of the radiator and you will feel a wingnut. You can loosen the drain knob with pliers, but a small crescent wrench on bolt attached to wingnut will prevent any stripping. The knob will only need a turn or less to loosen,,,,then you can use your fingers to adjust flow.

2003 impala heater quits working sometimes and it overheats sometimes

You should have it checked out right away, before the overheating does any damage to the engine. The whole coolant system should be inspected to find the cause. It may be a simple fix, maybe not. Are you adding coolant constantly? Do your radiator fans come on when it starts to overheat?
When it gets too hot, it may be boiling coolant away, and the low coolant level will cause the heater to stop putting out heat.

Have u checked the coolant level? this type of problem useualy indicates the coolant is low, if it is low you need to have the engine cooling system tested for a leak, the coolant goes out somewhere.

Do i need thermostat 2003 impala

yes you need a thermostat, the thermostat creates a restriction in the cooling system so that the coolant stays in the radiator long enough for the cooler air to transfer heat out of the coolant it also allows the coolant to stay in the block long enough to absorb the heat created by the combustion process so that you have heat and that the radiator can perform its function of cooling the engine as described above
