What kind of fluid goes in hydraulic clutch system

Sorry no diagram. But here is how it works. In the start position(Power) the wire goes to the start fuse, from the fuse it goes to the clutch pedal switch. Push the pedal and it goes to the starter relay. On the other end is ground. If it is good it pulls the relay closed. On the closed end is battery power to the starter.

Most hydraulic clutch systems have a small reservoir near the brake master cylinder that uses DOT3 or DOT4 brake fluid. Some systems,however, use the brake master cylinder for the clutch fluid supply.

If you mean the clutch throw out bearing??? No fluid goes into it, as it is sealed with grease packing inside. You may have a hydraulic clutch that actuates it, and that takes brake fluid. On the resevoir cap lists what kind. (DOT 3 or 4) This system is like a minature brake system, closed.

Hydraulic clutches use brake fluid.

HYDRAULIC SYSTEM BLEEDING Do not use fluid which has been bled from a system to fill the reservoir as it may be aerated, have too much moisture content or possibly be contaminated. Clean the dirt and grease from the cap to ensure that no foreign substances enter the system. It is also important to maintain the fluid level in the clutch reservoir to the top step with hydraulic clutch fluid Hydraulic Clutch Fluid GM P/N 12345347 or equivalent.

1. Attach a hose to the bleeder screw on the clutch actuator assembly and submerge the other end of the hose in a container of hydraulic clutch fluid.
2. Depress the clutch pedal slowly and hold.
3. Loosen the bleeder screw to purge air.
4. Tighten the bleeder screw to 18 inch lbs. (2 Nm).
5. Let up on the clutch pedal.
6. Repeat Steps 2 through 5 until all air is purged from the system.
7. Fill the reservoir to the top step with hydraulic clutch fluid.
8. Repeat this bleeding procedure if there is a grinding noise during the clutch spin down procedure.

Hydraulic Clutch System BLEEDING The clutch system can be bled using a pressure bleeder. Follow the instructions that come with the pressure bleeder for the proper pressure bleeding procedure. The maximum line pressure while pressure bleeding must not exceed 36 psi (248 kPa). NOTE: To bleed a clutch manually requires the assistance of a second person, a section of hose that is compatible with brake fluid (preferably clear) and fits the slave cylinder bleed screw snugly and a container to catch the fluid that is bled through the system. As brake hydraulic fluid easily absorbs moisture, always use fresh fluid when bleeding a hydraulic system.

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. To bleed the system perform the following:
   1. Top off the hydraulic fluid reservoir using a fluid that meets the standards of the vehicle's hydraulic system.
   2. Open the clutch slave cylinder bleed screw and press the clutch pedal to the floor and hold the pedal down.
   3. Close the clutch slave cylinder bleed screw.
   4. Release the clutch pedal.
   5. Check the hydraulic fluid level and top off as necessary.
3. Repeat the above steps until the discharged fluid is clean and no air bubbles appear during the bleeding process.

The clutch and brake system use the same reservoir, there is a hose coming out from the side of the reservoir that goes over to the clutch master cylinder. Sometimes the brake fluid level goes low as brake pads wear and lowers the fluid level too low to work the clutch. Hope this helps, let me know.

Hello.

All Toyota vehicles take standard brake fluid for the clutch hydraulics.

in a car this 'new' prob. hydraulic. check clutch fluid reservoir- should be near brake fluid res.- will be smaller- if fluid is low, or empty- may be clutch master cylinder, or clutch 'slave' cylinder is leaking. check for leak under car, should smell like 'brake' fluid. if your brake master- both reservoirs are to the full line, and there's fluid under car, close to where clutch master is located, or near front of , or side, of tranny- then it's a clutch problem of some kind (as if you didn't already know this!!) relatively new vehicle (by my standards!), should have hydraulic clutch.
do you mean- when you depress the clutch pedal, it goes to the floor, and you can't shift into any gear??
should have asked this first! front wheel drive or rear? i'll guess front wheel drive. may have hyd. fluid leak in master or slave. (apologize for 'terms', but as 'male & female connectors', it's traditional, non-racist and non-sexist nomenclature!!) gotta' be careful, in the 21st century!! if there are, as i stated previously, 2 similar reservoirs, close to each other, then you prob. have hydraulic clutch. may need 'master' rebuilt, or replaced, or 'slave' replaced-it can be rebuilt, but prob not cost effective!
sorry to be 'long-winded/ texted', good luck!
