Of course
next to the radiator cap on top of the radiator
You shouldn't need to "bleed" the radiator in your Forester. If you top off the coolant in the radiator the next time you check the top of your radiator is empty again? You have a blown head gasket. Voice of experience here. --Ken
Yes.
To bleed a radiator, locate the bleed valve at the top of the radiator and use a radiator key or screwdriver to open it slightly. As air escapes, you will hear a hissing sound. Once water starts to come out, close the valve. This will remove trapped air and improve the radiator's efficiency.
There are no bleed valves on the engine, if that is what you mean.
There is a small brass valve on the top of the thermostat housing where it attaches to the top radiator hose. Loosen it and then fill the radiator until coolant comes out of the valve and then quickly close it. This is only for an impala with the 3.8 liter engine though I believe there are two valves on the 3.4.

On top of the thermostat housing is a bleed valve. Loosen the top nut first, this will bleed it. There is another one on the radiator, but I haven't found it yet.
on the top radiator hose.
When the engine is cold, remove the radiator cap, top off with a 50/50 mix, and start the engine. This will allow air to escape from the radiator. It may also have bleeder valves located high on the cooling system. The location will be listed in your owner's manual.
You don't bleed the water pump, you bleed the cooling system. Just jack up the front of the car or park it on an uphill incline and remove the radiator cap. Start the engine and let it run until no more air bubbles are escaping from the radiator. If it has bleeder valves use them to bleed the system. The water pump will bleed right along with the rest of the system.
not all cars have bleeder valves; it may be located on the intake manifold or the pipe neck that the radiator hose goes into
