Vehicle Care 10-17 Hydraulic Clutch The hydraulic clutch linkage in the vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. When to Check and What to Use Engine Air Cleaner/Filter The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 10‑6 for reservoir location. It is not necessary to regularly check clutch fluid unless a leak in the system is suspected. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. Refer to the Maintenance Schedule to determine how often to check the fluid level in the clutch master cylinder reservoir and for the proper fluid. See Recommended Fluids and Lubricants on page 11‑11. The engine air cleaner/filter is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑6 for more information on location. How to Check and Add Fluid The proper fluid should be added if the level does not reach the bottom of the diaphragm when it is in place in the reservoir. See the instructions on the reservoir cap.
