used car/fluid questions

Okay,I just bought a used car and was wondering which fluids I should replace. I already replaced oil and a new filter. Which should I get next? It's a stick w/ no power brakes btw.

How old is it? Alot of people forget to flush the cooling system out, if it's several years old I'd get the radiator flushed.

91........

get a GOOD coolant flush done, dont just replace the fluid. If your looking to kill time one afternoon, maybe even replace the thermostat.
