Also may I recommend to change the clutch fluid (DOT3 brake fluid) and refresh both, coolant and power steering fluids once you're in there.
Make sure to use the correct antifreeze.
As far as clutch is concerned in my case the method of changing what's in the reservoir, pump the pedal 15 times and repeat until fluid stays clean did absolutely NOT work. Better work it through from top to bottom via the bleed valve (not sure if '90 have one).
