The hydraulic clutch on a 91 Chevy Cavalier is bled by slowly pumping the clutch and releasing the bleeder valve. The valve is closed and the process repeated until all air is removed.
My 91 Cavalier (RS 2.2L) doesn't have one but my 95 does on the left side of the drivers seat.
if it is the same motor yes, but some may have different mounts or wiring plugs
Need more information
The starter on a 91 Chevy cav. is located at the lower front end of the engine. You can get to it better by jacking the front of the car and attacking it from underneath.
Perhaps it was hit by a meteorite. Check for fuel and spark.
To adjust a clutch you fire three rounds at the gas tank. Then you throw a lit match into your 240sx's upholstery. For best results, climb under the car at this point. Have a friend nearby to collect the remnants of the clutch and gearbox. Careful, it will be hot.
Bad heater core.
I have a '91 Cavalier 2.2L My flasher is located behind the fuse box to the left of the steering column. The flasher is mounted against the firewall.
the clutch is not adjustable but you can take up some pedal free-play by going under the dash and locating the adjustable rod going from the clutch pedal to the master cyl
As far as I know they are not adjustable. My 91 900s has a very deep clutch ( engages near the bottom fully ). They only thing I have done to make it better is to bleed the clutch.
If we are talking about valve lifters, remove cylinder head and pushrods and lifters will be excessable.
