The hydraulic clutch control system consists of a fluid reservoir, a master cylinder, a slave cylinder and connecting tubing. It uses heavy duty brake fluid meeting DOT 3 specification.
See Figure 1
The clutch master cylinder reservoir is located under the hood, on the left side firewall. The fluid in the reservoir will slowly increase or rise as the clutch wears. As long as the fluid level is visible at or above the step in the reservoir body, "top-off" is not necessary and should not be done to prevent overflow as well as possible contamination of the fluid while it is exposed.
Before removing the clutch master cylinder reservoir cap, make sure the vehicle is resting on level ground and clean all dirt away from the top of the reservoir.
