I believe that a 2001 Focus will have a hydraulic clutch. If so, there is no adjustment required... In other words, or to add, if Your clutch is catching very high up, you may need a new clutch. Check hydraulic fluid if catching very low.
In the RADIATOR. Good luck doing that. It goes in the expansion tank. Open cap cool and add. Let warm up and check level.
