. The air conditioning system is filled with chemical refrigerant,
which is hazardous. The AIC system should be serviced only by
trained technicians using approved refrigerant recoverylrecycling
equipment, trained in related safety precautions, and familiar with
regulations governing the discharging and disposal of automotive
chemical refrigerants.
. Do not expose any part of the AIC system to high temperatures
such as open flame. Excessive heat will increase system pres-
sure and may cause the system to burst.
Some aerosol tire inflators are highly flammable. Be extremely
cautious when repairing a tire that may have been inflated using
an aerosol tire inflator. Keep sparks, open flame or other sources
of ignition away
from the tire repair area. Inflate and deflate the
tire at least four
times before breaking the bead from the rim.
Completely remove the tire from the rim before attempting any re-
pair.

CAUTIONS-
See also WARNINGS
- if you lack the slqills, tools and equipment, or a suitable worl(shop
for any procedure described in this manual, leave such repairs to
an authorized BMW dealer or other qualified shop.
BMW is constantly improving its cars and sometimes these
changes, both in parts and specifications, are made applicable to
earlier models. Therefore, part numbers listed in this manual are
for reference only. Always check with your authorized BMW deal-
er parts department for the latest information.
Before starting a job, make certain that you have all the neces-
sary tools and parts on hand. Read ail the instructions thorough-
ly, and do not attempt shortcuts. Use tools appropriate to the
work and use only replacement parts meeting BMW specifica-
tions.
Use pneumatic and electric tools only to loosen threaded parts
and fasteners. Never use these tools to tighten fasteners, espe-
cially on light alloy parts. Always use a torque wrench to tighten
fasteners to the tightening torque specification listed.
Be mindful of the environment and ecology. Before you drain the
crankcase, find out the proper way to dispose of the
oil. Do not

If a normal
or rapid charger is used to charge battery, the battery
must be disconnected and removed from the vehicle in order to
avoid damaging the vehicle.
- Do not quick-charge the battery (for boost starting) for longer
than one minute. Wait at least one minute before boosting the
battery a second time.
* Connect and disconnect a battery charger only with the battery
charger switched off.
- Sealed or "maintenance free" batteries should be slow-charged
only, at an amperage rate that is approximately 10% of the bat-
tery's ampere-hour (Ah)
rating.
. Do not allow battery charging voltage to exceed 16.5 volts. If the
battery begins producing gas or boiling violently, reduce the
charging rate.
Boosting a sulfated battery at a high charging rate
can cause an explosion.

General
ADVICE FOR THE BEGINNER
The tips that follow are general advice to help the do-it-your-
self BMW owner
periorm repairs and maintenance taslts
more easily and more professionally.
Planning ahead
Know what the whole job requires before starting. Read the
procedure thoroughly, from beginning to end, in
orderto know
just what to expect and what parts will have to be replaced.
Workshop practices
Keeping things organized, neat, and clean is essential to do-
ing a good job. When working under the hood, iender covers
will protectthe finish from scratches and otherdamage. Make
sure the car finish is clean so that dirt under the cover does
not scratch the iinish.
Any repair job will be less troublesome if the parts are clean
For cleaning old parts, there are many solvents and parts
cleaners commercially available.
For cleaning parts prior to assembly, commercially available
aerosol cans of parts cleaner or brake cleaner are handy to
use, and the cleaner will evaporate completely.
WARNING-
Most solvents used for cleaning parts are highly flammable
as well as toxic, especially in aerosol form. Use with extreme
care. Do not smoke. Do not use these products indoors or
near any source of heat, sparks or flame.
Non reusable fasteners
Many fasteners used on the cars covered by this manual
must be replaced with new ones once they are removed.
These include but are not limited to: bolts, nuts (self-locking,
nylock, etc.), roll pins, clips and washers. Genuine BMW
parts should be the only replacement parts used for this pur-
pose.
Some bolts are designed to stretch during assembly and are
permanently altered, rendering them unreliable once re-
moved. These are known as torque-to-yield fasteners. Al-
ways replace fasteners where instructed to do so. Failure to
replace these fasteners could cause personal injury
orvehi-
cle damage. See an authorized BMW dealer for applications
and ordering information.

Basic tool requirements
The basic hand tools described below can be used to accom-
plish most of the simple maintenance and repair tasks.
Screwdrivers
4 The common flat-blade type, Phillips type, and TorxO type
screwdrivers will handle almost all screws used on
BMWs.
Two or three different sizes of each type will be required,
since a screwdriver of the wrong size will damage the screw
head.
Wrenches
4 Wrenches come in different styles, including open-end. 12
point box-end,
6 point box-end and flare nut. The basic open-
end wrench is the most widely used, but grips on only two
sides. The box-end wrench has better grip on all six sides of
a nut or bolt.
A 12 point box-end can loosen a nut or bolt where there is less
room for movement, while
a 6 point box-end provides better
grip. For hex fasteners on fluid lines, like brake lines and fuel
lines, a flare-nut wrench offers the advantages of a box-end
wrench with a slot that allows it to fit over the line.
The combination wrench is the most universal. It has one
open-end and one box-end. 10 mm and 13 mm wrenches are
the most common sizes needed.
A more complete set of
wrenches would include
6 mm through 19 mm sizes.
