while the pressure is released from the cooling system.
When you are sure all the pressure has been released, turn
and remove the pressure relief cap (still with a cloth).
NOTE:
Allow the engine to cool before checking the engine
coolant level.
z Key in OFF position.
z Visually check the engine coolant level at the degas bottle or
coolant expansion tank.
z Is the engine coolant level within specification? A2 CHECK THE PRESSURE RELIEF CAP
z
Carry out the Cap— 3.8L or Cap—4.6L test. Go to Component
Tests in this section.
z Is pressure relief cap/radiator cap OK? Yes
GO to
A3 .
No
INSTALL a new
pressure relief
cap/radiator cap. TEST
the system for normal
operation. A3 CHECK THE ENGINE COOLANT FOR INTERNAL LEAK
z
Key in OFF position.
z Inspect the engine coolant in degas bottle/coolant expansion
tank for signs of transmission fluid or engine oil.
z Is oil or transmission fluid evident in the coolant? Yes
If engine oil is evident,
REFER to
Section 303 -
00 . If transmission fluid
is evident, REPAIR or
INSTALL a new radiator
as necessary.
No
GO to A4 .
A4 CHECK THE ENGINE AND THE TRANSMISSION FOR
COOLANT z
Remove the oil level dipstick from the engine and the
transmission.
z Is coolant evident in the oil or transmission fluid? Yes
If coolant is in engine,
REFER to
Section 303 -
00 . If coolant is in
transmission, REPAIR
or INSTALL a new
radiator as necessary.
To repair the automatic
transmission, REFER to
Section 307 - 01 .
No
GO to A5 .
A5 PRESSURE TEST THE ENGINE COOLING SYSTEM
z
Pressure test the engine cooling system. Go to Component
Tests in this section.
z Does the engine cooling system leak? Yes

DESCRIPTION AND OPERATION
Starting System
Starter Motor
The starter motor is a 12-
volt unit that has the starter solenoid mounted on the drive end housing and
functions as follows:
zThe current flows through the solenoid energizing coil until the solenoid plunger is at the end of
its travel.
z The plunger closes a set of contacts that bypass the energizing coil, letting the holding coil keep
the starter drive engaged and passing starting current to the starter motor.
z The motor is energized when the starter solenoid contacts are closed.
z The starter drive engages the flywheel ring gear and starts the engine.
z An overrunning clutch in the starter drive protects the starter motor from excessive speed when
the engine starts.
Starter Relay
The starter interrupt relay consists of:
zpull in coil and contacts
When the ignition switch is in the START position:
zthe pull- in coil is activated and pulls the contacts together.
z current passes through the starter relay from the engine compartment power distribution box to
the starter solenoid.
Clutch Pedal Position (CPP) Switch
The CPP switch for:
za manual transmission closes when the clutch pedal is depressed, completing the starting
circuit.
z an automatic transmission is a jumper inserted in place of the CPP switch to complete the
circuit.
Starter System — Operation
When the ignition switch is turned to the START position the starter relay switches power to the starter
solenoid causing the starter motor to engage as long as:
zthe clutch pedal is depressed (manual transmission only).
z the digital transmission range (TR) sensor is in PARK or NEUTRAL (automatic transmission
only).
