I have replaced the Clutch Slave for a 1990 Supra Turbo, and after the next day all the Fluid leaks out from the resevior.I don know wher the fluid goes. what should I do next? Thank You, Frank

Not sure of the model EX, but it probably has a clutch hydraulic slave and master cylinder that has leaked out the hydraulic fluid. Fill the clutch master cylinder (near the brake master cylinder) with brake fluid and pump the clutch pedal several times. The clutch work again until the fluid leaks out, so the permanent fix is to replace the master and or slave cylinders and bleed the system. Other models have a clutch cable that would need replacing in this case

The clutch fluid is also your brake fluid. If it is low then you have a leak somewhere, could be your slave cylinder, or even brake pads are low

im assuming its a vy clubsport?
Make sure you remove all the old fluid from clutch resevior and clean it out properly.
You will need to raise the vehicle on a hoist or atleast 4 cat stands .
you will need 3 people in total to get the job done correctly.
fill the clutch resevior with new fluid.
get someone to stay under the car to open slave cylinder to release air.
someone to seat to drivers seat to pump clutch pedal.
and someone at resevior all the time to top up fluid.
when bleeding system just pump the pledal slowly when the person bleeding slave cylinder says hold.hold the pedal down with light pressure when the slave is open you will get air and then little fluid .
repeat process until just good flow of fluid comes out ,once this happens you should have a good pedal..
hope this helps you

make sure that the resevior is full then have someone push down on the clutch pedal a few times and hold it down on the last stroke while you open the slave cylinder valve. then repeat as necessary until fluid comes out. Dont't let the resevior run out of fluid.

no fluid in the clutch reservoir due to a failed clutch slave cylinder
time to replace both the clutch slave and master cylinder

I just did mine 2 days ago. There is a allen wrench spot on the back of the slave unit in the front of ******. You need one person with a good leg to get in truck and start pumping clutch one person under truck with allen wrench to loosen and tighten screw. Guy inside needs to pump maybe like thirty times up and down before it pays to open bleeder on slave unit.The guy inside needs to hold down clutch while the guy opens watches then closes bleeder. then guy from inside needs to go under hood to make sure the resevour still has enough fluid.It takes brake fluid in resevour. You don't want the resevour to run low on fluid or you will have to start all over. I had a small leak in the line leading to slave cylinder were I lost fluid and that's how I got air in system make sure you don't have any leaks. Good luck I know it works I have more clutch know then a year ago when I had the slave unit changed.

possible bad slave cylinder on transmission, you do have a hydraulic clutch, have you checked the fluid in it? it might be your problem. hope i helped!!

is the slave cylinder inside the bellhousing??

Jack up the car with adequet support have someone work the clutch in and out,obseve the slave cylinder when the clutch pedal is realeased--is it free or hanging up -still tight then problem with the master or slave.If not then the clutch plate may be stickly on the splines when cold,

Replace the clutch master and slave cylinders.
I recently had the exact same problem on my car.
