fan is not coming on at proper temperature and engine is
overheating.
Corrado SLC, Passat GLX
The cooling fan is either a 1 or 2-speed motor. If vehicle is
equipped with single-speed motor, the fan comes on at 198-207øF (92-
97
øC) and turns off at 183-196øF (84-91øC). If equipped with a 2-speed
motor, low speed of cooling fan should come on at 198-208
øF (92-98øC)
on vehicles without A/C, or 183-207
øF (84-97øC) on vehicles with A/C.
Low speed will shut off at 183-196
øF (84-91øC) on all vehicles. High
speed comes on at 210-226
øF (99-108øC) on vehicles without A/C, or
201-226
øF (94-108øC) on vehicles with A/C. High speed will shut off at
196-220
øF (91-104øC) on all vehicles.
After-Run Thermoswitch
An after-run switch is used to help prevent fuel
vaporization. The thermoswitch turns cooling fan on when temperatures
in engine compartment exceeds 230
øF (110øC), and turns it off at 217øF
(103
øC).
Passat GL
The cooling fan is a 2-speed motor. Low speed of cooling fan
should come on at 198-207
øF (92-97øC) and will shut off at 183-196øF
(84-91
øC). High speed comes on at 210-221øF (99-105øC) and will shut
off at 196-208
øF (91-98øC).
TROUBLE SHOOTING
NOTE: Trouble shooting information not available from manufacturer.
TESTING
ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Corrado SLC & Passat GLX (2.8L)
1) Ensure engine is cold. Connect Scan Tester (VAG 1551) to
Data Link Connectors (DLC) located in center console, in front of
shift lever.
2) Start engine and allow it to idle. With scan tester in
READ TEST VALUE BLOCK function, select group No. 01 and read coolant
temperature value in field No. 2 of scan tester. Temperature value
must increase uniformly without interruption. If value increases as
specified, select END OUTPUT function on scan tester.
3) If displayed value does not change or if engine
malfunctions during certain temperature ranges, turn ignition off and
measure engine coolant temperature sensor resistance. See ECT SENSOR
LOCATION table. Replace ECT sensor if resistance is not within
specification. See ECT SENSOR RESISTANCE table.

allow it to idle. With scan tester in READ MEASUREMENT BLOCK function,
read coolant temperature value in channel No. 1 of scan tester.
2) If temperature value increases uniformly without
interruption, sensor and its circuit are okay. Select END OUTPUT
function on scan tester. If display value is incorrect, test wiring
harness for open or short circuit. See Corrado SLC WIRING DIAGRAMS,
or Passat WIRING DIAGRAMS articles.
3) If necessary, use test leads from Adapter Kit (VAG 1594)
to measure ECT sensor resistance. See ECT SENSOR LOCATION table.
Replace engine coolant temperature sensor if not within specification.

1993 ELECTRICAL
Volkswagen Starters - Bosch
Volkswagen; Corrado SLC, Passat
DESCRIPTION
Starter is a brush type, series-wound electric motor with an
overrunning clutch. Field frame is enclosed by commutator end frame
and drive bushing, and carries pole shoes and field coils. A splined
armature shaft drive end carries drive assembly.
TROUBLE SHOOTING
NOTE: See TROUBLE SHOOTING - BASIC PROCEDURES article in
GENERAL INFORMATION.
ON-VEHICLE TESTING
STARTER DOES NOT CRANK ENGINE
1) Ensure battery is fully charged. Make sure electrical and
ground connections are clean and tight. With ignition switch in START
position, measure voltage at spade terminal of starter solenoid.
Reading should be at least 8 volts. If voltage is as specified, check
engine for mechanical problems. If voltage is not as specified, go to
next step.
2) Measure voltage at ignition switch. If reading is at least
8 volts, check wiring between ignition switch and starter solenoid. If
voltage is not as specified, replace ignition switch.
3) Measure voltage at field (starter) terminal of starter
solenoid. If reading is 8 volts or more, repair or replace starter. If
reading is less than 8 volts, replace starter solenoid.
NOTE: On vehicles with automatic transmission, also check
park/neutral switch.
STARTER CRANKS TOO SLOWLY
Ensure engine crankcase is filled with recommended viscosity
oil. Check charging system to ensure battery is fully charged. Make
sure electrical and ground connections are clean and tight. If starter
still turns slowly, repair or replace starter.
VOLTAGE DROP TEST
Starter Main Terminal
Connect a voltmeter between starter main terminal and starter
body. Disconnect ignition coil positive terminal and operate starter.

1993 STEERING
Volkswagen - Power Rack & Pinion
Corrado SLC
DESCRIPTION & OPERATION
System consists of a vane pump, rack and pinion steering
gear, and an oil reservoir. Vane pump draws fluid from reservoir and
supplies it to flow control valve. Control valve directs fluid to
appropriate side of rack piston.
LUBRICATION
CAPACITY
Fluid capacity is approximately 1 qt. (.95L).
FLUID TYPE
Recommended fluid type is VW Hydraulic Oil No. G 002 000.
FLUID LEVEL CHECK
Remove reservoir cover. Start engine and let idle. Fluid
level should be between MIN and MAX marks on reservoir.
HYDRAULIC SYSTEM BLEEDING
1) Start engine and let idle. Ensure fluid is at proper
level. Turn steering wheel from lock to lock several times quickly.
2) Continue until fluid level remains at reservoir mark.
Ensure no bubbles appear in reservoir when steering wheel is turned.
Shut off engine. Ensure oil level does not rise more than 3/8" (10
mm).

NOTE: See WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES article in
the WHEEL ALIGNMENT section.
WHEEL BEARING
No adjustment is required.
BALL JOINT CHECKING
Raise and support vehicle. Inspect ball joints for excessive
play and damaged rubber boots. There should be no vertical or
horizontal ball joint play. Replace ball joint if any play is present.
REMOVAL & INSTALLATION
HUB & KNUCKLE ASSEMBLY
Use exploded view illustration when removing or installing
hub and knuckle assembly. See Fig. 1.
LOWER CONTROL ARM & BALL JOINT
Removal
1) Raise and support vehicle. Remove bolt retaining ball
joint at steering knuckle. Separate ball joint from housing. Leave
control arm hanging in mounts at subframe.
2) If control arm is not to be removed and ball joint is
riveted to control arm, drill out ball joint rivets using a 9/32" (7
mm) drill. After drilling rivets, chisel off rivet heads (if
necessary). If ball joint is bolted to control arm, remove bolts.
Remove ball joint.
3) If control arm is to be removed from vehicle, remove
stabilizer bar link rod nut, washers, and bushings. Remove pivot bolt
and "U" bracket housing inner pivot pin. Slide out control arm.
NOTE: On vehicles with automatic transmission, engine may have to
be lifted slightly to gain access to pivot bolts.
Inspection
Check lower control arm bushings for excessive wear, cracks
or contamination. Replace bushings if necessary. To replace bushings,
press out worn bushing. Select new bushing and press into position.
Ensure bushing does not twist when seating into place.
Installation
Slide new ball joint into slot in control arm. Install and
tighten ball joint retaining bolts. Install lower control arm to
subframe. Install ball joint into steering knuckle. To complete
installation, reverse removal procedure. Tighten control arm bolts
with vehicle on ground. Tighten all bolts and nuts to specification.
See TORQUE SPECIFICATIONS table at end of article. Check wheel
