Where is the clutch fluid reservoir

The brake fluid reservoir feeds the clutch but hydraulic fluid doesn't squeak. If it was low, you'd have a leak and a soft pedal. Look instead for things like the pivot bushing the pedal is hinged on, and the return spring. The hooks on the end of the spring will rotate slightly and can squeak on the pins they're hooked to. Mopar Spray White Lube works good for things like that. Other manufacturers have similar products with their own name on it. That grease flows easily into tight places, then the juice evaporates and leaves the grease behind.
