1993 honda Civic.

How do I bleed the clutch fluid? I think I know where the bleeder valve is, but I`m not positive. I was told that I needed to have a vacuum to suck out the fluid. Is this true? Or can I just crack the bleeder valve and then pump the clutch while a friend adds new fluid? Dot 3 right? Would I notice a difference between Dot 4 vs Dot 3?

Thanks!

PS 320k miles and still has the original clutch.
