Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole. 3. Install the filler plug. Be sure the plug is fully seated. Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 5-12 for reservoir location. It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. 5-23
