2001 mercury cougar, master cylinder ran dry because slave cylinder below is leaking at the firewall. I filled the master cylinder and tried bleeding the clutch at the transmission until fluid stream consistent. I still have no clutch. There is a rubber hose that runs from the bottom of the master cylinder to the firewall (in to slave cylinder), immediately below that is where it's leaking from (slave cylinder out). The clutch was working fine prior to the leak. Do I need to replace the clutch when I replace the slave cylinder?

SOURCE: can you bleed the water cooling system on 1999 mercury cougar

This is extremely important on some cars, for instance my BMW. 1. Have the car parked in a slight uphill slope. Make sure there is enough coolant in the expansion jar.
2. Start the engine and wait for the thermostat to open (upper radiator hose becomes warm).
3. Open up the radiator bleeding nipples slightly with a large screwdriver (bleeding nipples normally made of plastic with a '+* for a screwdriver to fit, at the highest points in the cooling circuit).
4. Allow air bubbles to fizzle out until you get a steady stream of coolant leaking out, use rags to capture leaking coolant.
5. Then close the bleeding nipples, switch off the engine and wait a few minutes for pressure to come down.
6. Open up the cap on the expansion vessel carefully and fill just below the "hot" marking.
7. Check levels again after a few miles and refill further if needed.

Done.

Check the level and make sure it wasn't overfilled. (running, hot and in park) If the level is ok, look for the vent. It should be on top of the trans, maybe by the linkage. It should be covered by either a metal or rubber cap. That may be clogged.

if you look at the firewall area you usually can see rubber or plastic black plugs to run wiring to the passenger compartment; look by the left side kick panel on the floor next to your brake pedal; good area to drill if you have to ; make sure you insulate any cable or power supply going through the firewall so the wire is protected from rubbing or vibration

starter replacement itself would not effect transmission,check that transmission cooler lines to radiator were not loosend or damaged changing starter.place a piece of cardboard under vehicle to help pinpoint leak.
