GENERAL INFORMATION
METRIC CONVERSIONS
METRIC CONVERSIONS
Metric conversions are making life more difficult for the
mechanic. In addition to doubling the number of tools required,
metric-dimensioned nuts and bolts are used alongside English
components in many new vehicles. The mechanic has to decide which tool
to use, slowing down the job. The tool problem can be solved by trial
and error, but some metric conversions aren't so simple. Converting
temperature, lengths or volumes requires a calculator and conversion
charts, or else a very nimble mind. Conversion charts are only part of
the answer though, because they don't help you "think" metric, or
"visualize" what you are converting. The following examples are
intended to help you "see" metric sizes:
LENGTH
Meters are the standard unit of length in the metric system.
The smaller units are 10ths (decimeter), 100ths (centimeter), and
1000ths (millimeter) of a meter. These common examples might help you
to visualize the metric units:
* A meter is slightly longer than a yard (about 40 inches).
* An aspirin tablet is about one centimeter across (.4 inches).
* A millimeter is about the thickness of a dime.
VOLUME
Cubic meters and centimeters are used to measure volume, just
as we normally think of cubic feet and inches. Liquid volume
measurements include the liter and milliliter, like the English quarts
or ounces.
* One teaspoon is about 4 cubic centimeters.
* A liter is about one quart.
* A liter is about 61 cubic inches.
WEIGHT
The metric weight system is based on the gram, with the most
common unit being the kilogram (1000 grams). Our comparable units are
ounces and pounds:
* A kilogram is about 2.2 pounds.
* An ounce is about 28 grams.

Torque is somewhat complicated. The term describes the amount
of effort exerted to turn something. A chosen unit of weight or force
is applied to a lever of standard length. The resulting leverage is
called torque. In our standard system, we use the weight of one pound
applied to a lever a foot long, resulting in the unit called a foot-
pound. A smaller unit is the inch-pound (the lever is one inch long).
Metric units include the meter kilogram (lever one meter long
with a kilogram of weight applied) and the Newton-meter (lever one
meter long with force of one Newton applied). Some conversions are:
* A meter kilogram is about 7.2 foot pounds.
* A foot pound is about 1.4 Newton-meters.
* A centimeter kilogram (cmkg) is equal to .9 inch pounds.
PRESSURE
Pressure is another complicated measurement. Pressure is
described as a force or weight applied to a given area. Our common
unit is pounds per square inch. Metric units can be expressed in
several ways. One is the kilogram per square centimeter (kg/cmý).
Another unit of pressure is the Pascal (force of one Newton on an area
of one square meter), which equals about 4 ounces on a square yard.
Since this is a very small amount of pressure, we usually see the
kiloPascal, or kPa (1000 Pascals). Another common automotive term for
pressure is the bar (used by German manufacturers), which equals 10
Pascals. Thoroughly confused? Try the examples below:
* Atmospheric pressure at sea level is about 14.7 psi.
* Atmospheric pressure at sea level is about 1 bar.
* Atmospheric pressure at sea level is about 1 kg/cm
ý.
* One pound per square inch is about 7 kPa.

Volkswagen Power Mirrors
Volkswagen; Corrado SLC, Passat
DESCRIPTION & OPERATION
Mirrors can be adjusted electrically from inside by operating
control knob on driver door panel. Adjustment control operates only
when ignition is on. To adjust driver-side or passenger-side mirror,
rotate control knob to "L" or "R". Control knob is a 4-way rocker
switch which is pressed top (up), bottom (down), left (out) or right
(in). See Fig. 1.
If electrical control of mirror does not operate, adjust
mirror by hand by pushing lightly on edge of mirror glass. When rear
defogger is on, outside mirrors are electrically heated.Fig. 1: Controlling Mirror Switch

TROUBLE SHOOTING
Left Or Right Power Mirror Inoperative
Check power mirror switch, power mirror motor(s), wiring,
ground connection(s) and fuse(s). Use operator's manual to identify
fuse(s).

while handling mirror glass (in case of accidental breakage).
NOTE: Mirror glass is only clipped in place.
Removal & Installation
Tape upper and lower edges of mirror housing. See Fig. 2 & 3.
Remove mirror glass using knife blade Pry Bar (VW-80-200). Pry off at
bottom and then top. While holding mirror, unplug electrical
connector, and remove mirror glass. To install, connect electrical
connector. Put mirror pins in notches, and press mirror into place.

CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may
exist until computer systems have completed a relearn
cycle. See the COMPUTER RELEARN PROCEDURES article in
GENERAL INFORMATION before disconnecting battery.
INTRODUCTION
Removal, overhaul and installation procedures are covered in
this article. If component removal and installation is primarily an
unbolt and bolt-on procedure, only a torque specification may be
furnished.
CAUTION: When disconnecting battery, obtain and record radio
anti-theft code. If wrong code is entered into radio after
power is restored, radio will become inoperable.

FUEL SYSTEM PRESSURE RELEASE
To relieve fuel system pressure, remove fuel pump fuse (No.
5, 13 or 18) or fuel pump relay to deactivate fuel pump. Place a clean
shop rag around fuel line fitting and slowly loosen fitting.
WARNING: Fuel system pressure release procedure is not available
from manufacturer. Fuel will discharge when disconnecting
fuel system components. Disconnect ignition coil output
stage wiring harness to deactivate ignition. DO NOT smoke
or work near heaters or other fire hazards. Keep a fire

fuel pump.
2) Using Wrench (3217), loosen fuel pump screw cap. Remove
flange and sealing ring from fuel tank opening. Loosen fuel pump by
twisting it to left. Remove fuel pump from fuel tank.
3) When installing fuel pump, ensure that fuel gauge sending
unit is not bent. Sending unit must be installed with a frontal angle
of 5 degrees. Align mark on flange with fuel tank. To complete
installation, reverse removal procedure.

valve. Disconnect accelerator cable from throttle body. Disconnect and
plug coolant hoses at throttle body.
3) Disconnect hose from air intake heated tube. Detach fuel
lines at cylinder head cover and remove from fuel rail. Disconnect
vacuum hose from fuel pressure regulator. Remove upper intake
manifold.
4) With upper intake manifold removed, disconnect wiring
harness from fuel injector(s). Pry off retaining clip(s) from
injector(s). To install injectors, lubricate "O" rings with fuel. To
complete installation, reverse removal procedure.

Volkswagen EGR Function Testing
All Models
EGR VALVE (EXCEPT DIESEL)
1) Run engine at idle speed. Using a hand-held vacuum pump,
apply 12 in. Hg to EGR valve. Engine should run rough or stall. If
not, check EGR valve pintle for movement. If EGR pintle is moving, EGR
port is plugged. If EGR valve does not function, replace EGR valve.
2) To check EGR port vacuum supply, connect vacuum gauge to
EGR vacuum line using a "T" fitting. Start engine and increase engine
speed to about 3000 RPM. Vacuum gauge should indicate vacuum. If
vacuum is not present, vacuum source is plugged. Repair as necessary
and repeat test.
