If there are no bleeder valves, simply remove the radiator cap, fill the radiator to the top, start the engine. With the engine running keep the coolant level full and watch for air bubbles. After the engine has reached full operating temp and you no longer see any air bubbles escaping shut it off and replace the cap. If there are bleeder valves use them to remove trapped air after the engine is running. Be careful as not to get burned by hot coolant.

How do you bleed the clutch on a 1991 Jeep Wranger 4-cylinder?
The clutch bleeding is similar to bleeding brakes. Although you must be sure the clutch cylinder is higher that the bleed fittings and if you can't get it to bleed you may have to purchase a tool at you local parts store that will force bleed the system. This will pull the air out of the system and pull the fluid in. Always be sure to keep the master clutch reservoir full at all times.
