General
4 An adjustable wrench can be a useful addition to a small tool
kit. It can substitute in a pinch if two wrenches of the same
size are needed to remove a nut and bolt. Use extra care with
adjustable wrenches, as they tend to loosen, slip, and dam-
age fasteners.
Jack stands
v
BOOBFNG
4 Strong jack stands are extremely important for any work that
is done under the car. Use only jack stands that are designed
for the purpose.
Blocks of wood, concrete, bricks, etc. are not
safe or suitable substitutes.
A
jaclc should be used only to raise the vehicle, not to support
the car for a long period. Always use
jack stands to support a
Jackstands are available in several styles. The best ones are
:
made of heavy material for strength, have a wide base for sta-
bility, and are equipped to positively lock in their raised posi-
tion. Get the best ones available.
Compared to
a wrench of the correct size, an adjustable
Oil change equipment
wrench is always second best. They should only be used
when the correct size wrench is not available. Choose one of
average size range, about
6 to 8 inches in length.
4 Changing engine oil requires a 17 mm socket or wrench to
loosen and tighten the drain plug and a drain pan (at least
8
quart capacity). A wide, low drain pan will fit more easily un-
der the car. Use a funnel to pour the new oil into the engine.
BMW engines use an oil filter canister with a disposable filter
cartridge insert. A
36 mm socket or wrench is required to re-
move the oil filtercanistercover. See

General
Torque wrench
A torque wrench is used to precisely tighten threaded fasten-
ers to a predetermined value. Many of the repair procedures
in this manual include BMW-specified torque values
in New-
ton-meters (Nm) and the equivalent values in foot-pounds
(ft-
Ib).
4 Several types of torque wrenches are available. An inexpen-
sive beam-type (top) is adequate but must be read visually. A
ratchet-type (bottom) can be preset to indicate (click) when
the torque value has been reached. They all do the same job,
but offer different convenience features at different prices.
The most convenient ones have a built-in ratchet, and can be
preset to indicate when a specific torque value has been
reached. Follow the wrench manufacturer's directions
for use
to achieve the greatest accuracy.
A torque wrench with a range up to about 150 Nm (1 10 ft-lb) BOIBFNG has adequate capacity for most of the repairs covered in this
manual. For recommended torque values of
10 Nm orbelow,
the English system equivalent is given in inch-pounds (in-lb).
These small values may be most easily reached using a
torque wrench calibrated in inch-pounds. To convert
inch-
pounds to foot-pounds, divide by 12.
Digital multimeter
4 Many of the electrical tests in this manual call for the mea-
surement of resistance (ohms) or voltage values. For safe
and accurate tests of sensitive electronic component and
systems, a multimeter or digital
volt/ohm meter (DVOM) with
high input impedance (at least
10,000Sr) should be used.
Some meters have automotive functions such as dwell and
pulse width that are useful for troubleshooting ignition and
fuel injection problems.
CAUTIOI\C
Vehicle electronic systems may be damaged by the high cur-
rent draw of a test light with a normal incandescent bulb. As
a general rule, use a high impedance digital multimeter or an
LED test light for all electrical testing.

With the introduction of synthetic oil and extended oil change
intervals, a new oil filterwith improved filter paper design was
introduced. The new filter paper resists deterioration caused
by high oil temperatures over an extended time.
Specification
Use BMW specified oil to top off the engine oil level between
oil changes.
BMW recommends the following engine oils:

4 If oil level is low, add oil by removing oil filler cap (arrow) on
top of cylinder head
(6-cylinder oil cap shown, V-8 is sirnilar).
- Add only amount needed to bring oil level to upper mark on
dipstick, using an oil of correct viscosity and grade.
Engine oil and filter, changing
A complete oil change requires new oil, a new filter insert kit,
and a new drain plug sealing washer. The tools needed, a
17
mm drain plug socket or box wrench, a 36 mm socket or
wrench, and a drain pan (8
- 10 US qt. capacity), are de-
scribed in
010 General.
NOTE-
If using a "fast 1ube"service facility for oil changes, make sure
the technician hand-starts and torques the engine oil drain
plug using hand-tools. Power tools can strip the threads of
the plug and the oil pan.
Run engine for afew minutes to warm engine oil. Shut engine
off.
With car on level ground, place drain pan under oil drain plug.
Using a
36 mm socket, loosen and remove oil filter housing
cover (arrow). Remove filter cartridge and discard any
0-
rings (V-8 engine oil filter housing shown, 6-cylinder oil filter
housing is sirnilar).
Using a socket or box wrench, loosen drain plug at oil drain
pan. Remove plug by hand and let oil drain into pan
(V-8 en-
gine oil drain plug shown, 6-cylinder drain plug is similar).
WARNING -
Pull the loose plug away from the hole quicldy to avoid being
scalded by hot oil. It will run out
quiclcly when the plug is re-

- Refill crankcase with oil. Approximate oil capacity is listed in
Tabled. Engine oil with filter change. Use dipstick to
check correct oil level.
- Start engine and check that oil pressure warning light
immediately goes out.
- Allow engine to run fora few minutes to circulate new oil, then
check for leaks at drain plug and oil filter. Stop engine and re-
check oil level
The section describes other routine maintenance done in the
engine compartment. Information on engine oil service is
giv-
enkar~ier inthis group.
For these procedures, it is not necessary for the car to be
raised and supported off the ground.
Accelerator and linkage
The accelerator and linkage at the throttle housing should be
lubricated periodically. Use ageneral purposeoil on the joints
and bearings of the linkage. Use a multipurpose grease on
the bearing points of the throttle plate.
Air filter, replacing
The specified replacement intervals forthe air filter are based
on normal use. If the car is operated primarily in dusty
conditions, the air filter should be serviced more frequently.

Engine lubrication
Oil pressure is generated by a gear-type pump bolted to the
bottom oi the engine block. The oil pump is chain driven off
the front of the crankshaft.

The oil pressure warning system consists of an oil pressure
switch mounted in the oil circuit and an instrument
panel
warning light. Other saiety features include:
Q A filter bypass to provide lubrication should the oil filter be-
come clogged.
An oil pump pressure relief valve to prevent excessive sys-
tem pressure.
CAUTIOI\C
If the red oil pressure warning light comes on or flashes on
while driving, always assume that the oilpressure is low. Stop
the engine immediately and make arrangements to test oil
pressure.

Battery, Starter, ~iternatorl
The battery is mounted in the right side of the luggage com-
partment, concealed behind a trim panel. Battery capacity is
determined by the amount of current needed to start the vehi-
cle and by the amount of current consumed by the electrical
system. This will vary from model to model.
BMW batteries are rated by
amperelhours (Ah) and cold
cranking amps (CCA) rating, which are listed on the battery.
The Ah rating is determined by the average amount of cur-
rent the battery can deliver over time without dropping below
a specified voltage. The CCA is determined by the battery's
ability to deliver starting current at
On F (-18" C) without drop-
ping below a specified voltage. Always replace the battery
with one having the same or higher ratings.
Battery testing
Battery testing determines the state of battery charge. On
conventional or low-maintenance batteries. the most com-
mon method of testing the battery is that
ofchecking the spe-
cific gravity of the electrolyte using a hydrometer. Before
testing the battery, check that the cables are tight and free of
- corrosion.
Hydrometer testing
Before hydrometertesting, load the battery with 15 amperes
for one minute. If the battery is installed in the vehicle, this can
be done by turning on the headlights without the engine run-
ning. The state of battery charge based on specific gravity
values are given in Table
b. Specific gravity of battery elec-
trolyte at
27" C (80°F).
The hydrometer indicates the specific gravity of the electro-
lyte. The more dense the concentration of sulfuric acid in the
electrolyte, the higher the state of charge
NOTE-
Electrolyte temperature affects hydrometer reading. Checlc
the electrolyte temperature with a thermometer. Add 0.004 to
the hydrometerreading
forevery 6°C (10°F) that the electro-
lyte is above 27°C
(80°F). Subtract 0.004 from the reading
forevery 6°C (10°F) that the electrolyte is below27"C
(80°F).
