1992 Golf GL Overheating

My 1992 Golf GL has been overheating.
I replaced the thermostat this past weekend, but it still overheats.

1) Is it likely that the NEW thermostat is faulty?
2) Is it more likely that it needs a new water-pump?
Is it true that the water-pump runs off the timing belt?
If so, is that more a professional job?

3) Are there any other possibilities/suggestions?

I'm just getting kinda desperate since this is my only ride
to/from work....

I'd say, check your coolant.

Thanks for your response.
What could be up with my coolant?
What am i to check?

Auto shops usually sell this little tube like thing that checks for your coolant. I can't remember the name of it, but its a small tube that has several little colored balls inside of it. I know that its used to test your coolant to see if it is working, or if you'll need to change the coolant.

The thermostat simply opens a valve when the engine needs coolant.
A "faulty" thermostat would normally stay open - allowing coolant to run through all the time.

Who are your coolant levels? - Is the resevoir constant (always requires top-up, always over-flowing - normal levels?

It could be that there is an air buble in the coolant system - the waterpump cannot push air.

the Waterpump and timing belt should be replaced by somebody that knows what they are doing

Turns out that my radiator fan wasnt engaging.. It works, but it isnt turning on automatically. I hot-wired it and put a switch inside the car to click it on and off as needed...
However, i would prefer that it works like it should.
Could it be the "Radiator Fan Relay"?
Is that likely?

could be a fan relay, also could be the cooling fan switch on the radiator.
