ENGINE ELECTRICAL SYSTEMS
STARTER MOTOR | REMOVAL AND INSTALLATION (Refer to illustration 19.3)
Detach the cable from the negative terminal of the battery. Caution: If the stereo in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery.
Detach the electrical connectors from the starter/solenoid assembly.
Remove the starter motor mounting bolts (see illustration). Note: If equipped with a manual transmission, it may be necessary to remove the clutch release cylinder. Remove the mounting bolts (see Chapter 8) and move the cylinder aside, but DO NOT disconnect the hydraulic line.
Remove the bracket from the upper section of the starter/solenoid assembly.
Note: It is necessary to loosen one or two of the bracket bolts to allow the starter/solenoid assembly to partially drop down to gain access to the remaining bracket assembly bolts and hardware.
Installation is the reverse of removal.
POWER BRAKE BOOSTER | CHECK, REMOVAL AND INSTALLATION
Depress the brake pedal several times with the engine off and make sure there's no change in the pedal reserve distance.
Depress the pedal and start the engine. If the pedal goes down slightly, operation is normal.
AIR TIGHTNESS CHECK
Start the engine and turn it off after one or two minutes. Depress the brake pedal slowly several times. If the pedal depresses less each time, the booster is airtight.
Depress the brake pedal while the engine is running, then stop the engine with the pedal depressed. If there's no change in the pedal reserve travel after holding the pedal for 30 seconds, the booster is airtight.
REMOVAL(Refer to illustration 11.7)
Power brake booster units shouldn't be disassembled. They require special tools not normally found in most automotive repair stations or shops. They're fairly complex and, because of their critical relationship to brake performance, should be replace with a new or rebuilt one.
To remove the booster, first remove the brake master cylinder (see Section 8).
