2004 Cavalier clutch cylinder mysteriously empty

Please help!!!!

2004 manual transaxle.. No visible signs of leaks, clutch cylinder mysteriously empty. Car shifts normal at 75,000 miles, the fluid had to go somewhere???. Topped cylinder off with fluid and car seems normal. I'm not into taking chances!!! Would rather not pull motor to install new clutch unless I have to! There looks to ba a bleeder near the Transmission housing where the hydraulic line enters the tranny. Will this bleed the whole system?

Help and advice appreciated!

    citsrc,



    I appreciate you help by all means! I looked today and while things are very cramped in that area, It seems there are no external bolts to loosen and allow easy replacment of the slave. I think I might have to drop the whole tranny! Intellegent engineering again!



    How would I troubleshoot the master clutch cylinder from the slave???



    Thanks,



    Marty

The fluid is going somewhere of course but your clutch lines do not run into the transmission itself it runs to a slave cyclinder that should be on the side of your transmission most likely where you seen that bleeder valve at normally if you can put fluid in the master cyclinder and you can shift gears fine it is your slave cyclinder that is going out if this is so all you have to do is unbolt it from the side of the tranny and replace it. It should only have 2 bolts, 1 line, and a rubber grommet on one end with a rod in it if you take it off just put the new one on the same way just in reverse order. hope every thing goes well.

As slave cylinders fail on a regular basis, I would find it difficult to believe that the gear box has to be interfered with to replace /repair the cylinder .IT may prove difficult to get to but a workshop manual would describe how to remove the cylinder

2000 hyundai elantra leaking clutch fluid, when low or empty lose clutch, then refill clutch works fine, leaking under car


The clutch hydraulic system is very simple, just 3 pieces. There is the clutch master cylinder with attached fluid reservoir-mounted on the firewall, there is a steel line from the master going down to the transaxle bell housing, and there is the clutch slave cylinder on the bell housing that the steel line connects to.
If yours is leaking under the car, it is probably the slave cylinder, either that or the steel line. Either one should be easy to replace.

Where can I find the hydrolic clucth resivoir and why would it be empty. Daughters car she is in Illinois and me Florida. Not much help from here but can let her know where to look for sure?


There should be a small cup size reservoir on the fender strut tower. Looks like thing in upper right corner of below picture. What usually happens to hydraulic clutches when they draw air, it the slave cylinder on the side of the transmission leaks and must be replaced. The system can then be bled of air and proper clutch operation restored. It would be difficult to restore clutch operation just by refilling the reservoir, especially with such a small reservoir. If it is necessary to get the car moving to get it repaired (slave cylinder replacement is a big job on this car, as the transmission must be removed), one could bleed the system with the bad slave cylinder and then drive a short distance. The clutch will likely fail again after about 100 or so cycles of the pedal. I will paste the bleed instructions below. These require someone to get under the car to open the slave bleeder. If you have more questions, please let me know.

Bleeding The Hydraulic System

Note: brake fluid is corrosive--please wipe any spilled fluid from painted or metal surfaces.
Manual Bleeding

  1. Fill the clutch reservoir with brake fluid. Check the reservoir level frequently and add fluid as needed.
  2. Connect one end of a vinyl tube to the bleeder plug on the slave cylinder and submerge the other end into a clear container half-filled with clean brake fluid.
  3. Slowly pump the clutch pedal 10-15 times without bring the pedal the full way up.
  4. Repeat Steps 2 and 3 until all of the air bubbles are removed from the system.
  5. Tighten the bleeder screw to 62 inch lbs. (7 Nm).
  6. Refill the master cylinder to the proper level.

Replacing the clutch slave cylinder:


Removal & Installation Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

  1. Disconnect the clutch master cylinder line from the transaxle by removing the C-clip.
  2. Remove the transaxle.
  3. Remove the clutch actuator cylinder bolts from the transaxle.
  4. Remove the clutch actuator cylinder.

To install:


NOTE Excessive amounts of lubricant on the input shaft splines can contaminate the clutch disc and cause clutch shudder.

  1. Lightly lubricate the inside diameter of the bearing with input shaft lubricant P/N 21005995 or equivalent.
  2. Install the clutch actuator cylinder (1) to the transaxle.
  3. Install the clutch actuator cylinder bolts.
  4. Tighten the bolts to 89 inch lbs. (10 Nm).
  5. Install the transaxle.
  6. Connect the clutch master cylinder line to the transaxle by pushing it in until it seats.
  7. Bleed the clutch hydraulic system.

My clutch pedal went to the floor in my 2003 chevy cavalier


check the clutch fluid level. if its empty, you have a leak, and you have air in the system. if there is no leak, and the fluid level is full, the problem lies in either the clutch master cylinder or slave cylinder.

2004 cavalier clutch pedal stays on floor,clutch not slipping. do i change clutch master cyl


Check for fluid leaks first along the line. Also check the mechanical linkage. Then try bleeding it. Changing the master cylinder is your last resort. That way you dont buy parts you don't need.

In order to check correctly, you would have to put the same viscosity of oil in the other 3 cylinders as well for their reading. Have you done a leak down test?

2004 Chevy Cavalier Cruise Control Problem


here are two switches that are the usual causes of the cruise kicking out. they are both under the dash. One is the switch for the brake lamps (stop light switch). the other is for the clutch if you have a manual transmission.

if you follow the brake pedal up under the dash you'll find two switches at the top of the pedal. (it may be one switch but I think its two). the top one would be for the cruise control. if the switch is loose it will cause the cruise control to think you're stepping on the brake and that will disengage the cruise control

same with the clutch pedal if you have a manual transmission; if the switch is loose it will indicate you are pushing the clutch pedal in and cause the cruise to kick out

other than that you'll have to check all of the connectors. If it does engage then the fuses and actuators should be good and it would be a loose connector or switch that's kicking it out

also, i assume your speedometer works; if its not then that's your problem as the cruise won't engage under 30 mph
