1991 BMW 5 SERIES oil change

0•4Introduction
The E30 3-Series range first became
available in the UK in March 1983, and
continued in production until April 1991, when
the revised E36 3-Series range (not covered
by this manual) was introduced. Convertible
and Touring (Estate) models were introduced
for 1988, and these models have continued in
E30 form to date.
The E28 5-Series models were introduced
in October 1981, and were superseded in
June 1988 by the revised E34 5-Series range,
Touring versions of which became available
from March 1992. Throughout this manual,
E28 models are also referred to as “old-
shape”, while E34 models are designated
“new-shape”.
The models covered by this manual are
equipped with single overhead cam in-line
four- and six-cylinder engines. Early 316 and
518 models are fitted with carburettors, but all
other models are fitted with fuel injection
systems. Transmissions are a five-speed
manual, or three- or four-speed automatic.
The transmission is mounted to the back of
the engine, and power is transmitted to the
fully-independent rear axle through a two-
piece propeller shaft. The final drive unit is
bolted solidly to a frame crossmember, and
drives the rear wheels through driveshaftsequipped with inner and outer constant
velocity joints.
The front suspension is of MacPherson
strut type, with the coil spring/shock absorber
unit making up the upper suspension link. The
rear suspension is made up of coil spring-
over-shock absorber struts, or coil springs
and conventional shock absorbers,
depending on model.
The brakes are disc type at the front, with
either drums or discs at the rear, depending
on model. Servo assistance is standard on all
models. Some later models are equipped with
an Anti-lock Braking System (ABS).
All models are manufactured to fine limits,
and live up to the BMW reputation of quality
workmanship. Although many of the models
covered by this manual appear complex at
first sight, they should present no problems to
the home mechanic.
Note for UK readers
The greater part of this manual was
originally written in the USA. Some of the
photographs used are of American-market
models, but the procedures given are fully

0•6Safety First!
Working on your car can be dangerous.
This page shows just some of the potential
risks and hazards, with the aim of creating a
safety-conscious attitude.
General hazards
Scalding
• Don’t remove the radiator or expansion
tank cap while the engine is hot.
• Engine oil, automatic transmission fluid or
power steering fluid may also be dangerously
hot if the engine has recently been running.
Burning
• Beware of burns from the exhaust system
and from any part of the engine. Brake discs
and drums can also be extremely hot
immediately after use.
Crushing
• When working under or near
a raised vehicle,
always
supplement the
jack with axle
stands, or use
drive-on
ramps.
Never
venture
under a car which
is only supported by a jack.
• Take care if loosening or tightening high-
torque nuts when the vehicle is on stands.
Initial loosening and final tightening should
be done with the wheels on the ground.
Fire
• Fuel is highly flammable; fuel vapour is
explosive.
• Don’t let fuel spill onto a hot engine.
• Do not smoke or allow naked lights
(including pilot lights) anywhere near a
vehicle being worked on. Also beware of
creating sparks
(electrically or by use of tools).
• Fuel vapour is heavier than air, so don’t
work on the fuel system with the vehicle over
an inspection pit.
• Another cause of fire is an electrical
overload or short-circuit. Take care when
repairing or modifying the vehicle wiring.
• Keep a fire extinguisher handy, of a type
suitable for use on fuel and electrical fires.
Electric shock
• Ignition HT
voltage can be
dangerous,
especially to
people with heart
problems or a
pacemaker. Don’t
work on or near the
ignition system with
the engine running or
the ignition switched on.• Mains voltage is also dangerous. Make
sure that any mains-operated equipment is
correctly earthed. Mains power points should
be protected by a residual current device
(RCD) circuit breaker.
Fume or gas intoxication
• Exhaust fumes are
poisonous; they often
contain carbon
monoxide, which is
rapidly fatal if inhaled.
Never run the
engine in a
confined space
such as a garage
with the doors shut.
• Fuel vapour is also
poisonous, as are the vapours from some
cleaning solvents and paint thinners.
Poisonous or irritant substances
• Avoid skin contact with battery acid and
with any fuel, fluid or lubricant, especially
antifreeze, brake hydraulic fluid and Diesel
fuel. Don’t syphon them by mouth. If such a
substance is swallowed or gets into the eyes,
seek medical advice.
• Prolonged contact with used engine oil can
cause skin cancer. Wear gloves or use a
barrier cream if necessary. Change out of oil-
soaked clothes and do not keep oily rags in
your pocket.
• Air conditioning refrigerant forms a
poisonous gas if exposed to a naked flame
(including a cigarette). It can also cause skin
burns on contact.
Asbestos
• Asbestos dust can cause cancer if inhaled
or swallowed. Asbestos may be found in
gaskets and in brake and clutch linings.
When dealing with such components it is
safest to assume that they contain asbestos.
Special hazards
Hydrofluoric acid
• This extremely corrosive acid is formed
when certain types of synthetic rubber, found
in some O-rings, oil seals, fuel hoses etc, are
exposed to temperatures above 400
0C. The
rubber changes into a charred or sticky
substance containing the acid. Once formed,
the acid remains dangerous for years. If it
gets onto the skin, it may be necessary to
amputate the limb concerned.
• When dealing with a vehicle which has
suffered a fire, or with components salvaged
from such a vehicle, wear protective gloves
and discard them after use.
The battery
• Batteries contain sulphuric acid, which
attacks clothing, eyes and skin. Take care
when topping-up or carrying the battery.
• The hydrogen gas given off by the battery
is highly explosive. Never cause a spark or
allow a naked light nearby. Be careful when
connecting and disconnecting battery
chargers or jump leads.
Air bags
• Air bags can cause injury if they go off
accidentally. Take care when removing the
steering wheel and/or facia. Special storage
instructions may apply.
Diesel injection equipment
• Diesel injection pumps supply fuel at very
high pressure. Take care when working on
the fuel injectors and fuel pipes.
Warning: Never expose the hands,
face or any other part of the body
to injector spray; the fuel can
penetrate the skin with potentially fatal
results.
Remember...
DO
• Do use eye protection when using power
tools, and when working under the vehicle.
• Do wear gloves or use barrier cream to
protect your hands when necessary.
• Do get someone to check periodically
that all is well when working alone on the
vehicle.
• Do keep loose clothing and long hair well
out of the way of moving mechanical parts.
• Do remove rings, wristwatch etc, before
working on the vehicle – especially the
electrical system.
• Do ensure that any lifting or jacking
equipment has a safe working load rating
adequate for the job.
A few tips
DON’T
• Don’t attempt to lift a heavy component
which may be beyond your capability – get
assistance.
• Don’t rush to finish a job, or take
unverified short cuts.
• Don’t use ill-fitting tools which may slip
and cause injury.
• Don’t leave tools or parts lying around
where someone can trip over them. Mop
up oil and fuel spills at once.
• Don’t allow children or pets to play in or
near a vehicle being worked on.

0•10Roadside Repairs
Puddles on the garage floor or drive, or
obvious wetness under the bonnet or
underneath the car, suggest a leak that needs
investigating. It can sometimes be difficult to
decide where the leak is coming from,
especially if the engine bay is very dirty
already. Leaking oil or fluid can also be blown
rearwards by the passage of air under the car,
giving a false impression of where the
problem lies.Warning: Most automotive oils
and fluids are poisonous. Wash
them off skin, and change out of
contaminated clothing, without
delay.
Identifying leaks
The smell of a fluid leaking
from the car may provide a
clue to what’s leaking. Some
fluids are distinctively
coloured. It may help to clean the car
carefully and to park it over some clean
paper overnight as an aid to locating the
source of the leak.
Remember that some leaks may only
occur while the engine is running.
Sump oil Gearbox oil
Brake fluid Power steering fluidOil from filter
Antifreeze
Engine oil may leak from the drain plug......or from the base of the oil filter.
Leaking antifreeze often leaves a crystalline
deposit like this.Gearbox oil can leak from the seals at the
inboard ends of the driveshafts.
A leak occurring at a wheel is almost
certainly brake fluid.Power steering fluid may leak from the pipe
connectors on the steering rack.

Maintenance schedule
The following maintenance intervals are based on the assumption
that the vehicle owner will be doing the maintenance or service work,
as opposed to having a dealer service department do the work.
Although the time/mileage intervals are loosely based on factory rec-
ommendations, most have been shortened to ensure, for example, that
such items as lubricants and fluids are checked/changed at intervals
that promote maximum engine/driveline service life. Also, subject to
the preference of the individual owner interested in keeping his or her
vehicle in peak condition at all times, and with the vehicle’s ultimate
resale in mind, many of the maintenance procedures may be
performed more often than recommended in the following schedule.
We encourage such owner initiative.
When the vehicle is new, it should be serviced initially by a factory-
authorised dealer service department, to protect the factory warranty.
In many cases, the initial maintenance check is done at no cost to the
owner (check with your dealer service department for more
information).

engine damage. Conversely, overfilling the
engine (adding oil above the upper mark) may
cause oil-fouled spark plugs, oil leaks, or oil
seal failures.
6To add oil, remove the filler cap located on
the valve cover (see illustrations). After
adding oil, wait a few minutes to allow the
level to stabilise, then pull the dipstick out and
check the level again. Add more oil if required.
Refit the filler cap, tightening it by hand only.
7Checking the oil level is an important
preventive maintenance step. A consistently
low oil level indicates oil leakage through
damaged seals or defective gaskets, or oil
burning (internal leakage past worn rings or
valve guides). The condition of the oil should
also be noted. If the oil looks milky in colour or
has water droplets in it, the cylinder head
gasket may be blown, or the head or block
may be cracked. The engine should be
repaired immediately. Whenever you check
the oil level, slide your thumb and index finger
up the dipstick before wiping off the oil. If you
see small dirt or metal particles clinging to the
dipstick, the oil should be changed (see
Section 6).
Engine coolant
Warning: Do not allow antifreeze
to come in contact with your
skin, or with the vehiclepaintwork. Rinse off spills immediately
with plenty of water. Antifreeze is highly
toxic if ingested. Never leave antifreeze
lying around in an open container, or in
puddles on the floor; children and pets are
attracted by its sweet smell, and may drink
it. Check with local authorities about
disposing of used antifreeze. Local
collection centres may exist, to see that
antifreeze is disposed of safely.
8All vehicles covered by this manual are
equipped with a pressurised coolant recovery
system. On most models, a white plastic
expansion tank (or coolant reservoir) located
in the engine compartment is connected by a
hose to the radiator. As the engine heats up
during operation, the expanding coolant fills
the tank. As the engine cools, the coolant is
automatically drawn back into the cooling
system, to maintain the correct level.
9The coolant level in the reservoir (see
illustrations)should be checked regularly.
Add a 40%/60% mixture of ethylene glycol-
based antifreeze to water (see illustration).
Warning: Do not remove the
expansion tank cap or radiator
cap to check the coolant level,
unless the engine is completely
cold! The level in the reservoir varies with
the temperature of the engine. When the
engine is cold, the coolant level should beabove the LOW mark on the reservoir.
Once the engine has warmed up, the level
should be at or near the FULL mark. If it
isn’t, allow the engine to cool, then remove
the cap from the reservoir.
10Drive the vehicle and recheck the coolant
level. If only a small amount of coolant is
required to bring the system up to the proper
level, plain water can be used. However,
repeated additions of water will dilute the
antifreeze. In order to maintain the proper
ratio of antifreeze and water, always top-up
the coolant level with the correct mixture.
11If the coolant level drops consistently,
there must be a leak in the system. Inspect
the radiator, hoses, filler cap, drain plugs and
water pump (see Section 29). If no leaks are
noted, have the expansion tank cap or
radiator cap pressure-tested by a BMW
dealer.
12If you have to remove the cap, wait until
the engine has cooled completely, then wrap
a thick cloth around the cap and turn it to the
first stop. If coolant or steam escapes, let the
engine cool down longer, then remove the
cap.
13Check the condition of the coolant as
well. It should be relatively clear. If it’s brown
or rust-coloured, the system should be
drained, flushed and refilled. Even if the
coolant appears to be normal, the corrosion

6 Engine oil and filter change
1
Warning: Prolonged skin contact
with used engine oil is
hazardous. Use a barrier cream
and wear gloves during this procedure.
Change out of oil-soaked clothing
immediately.
1Make sure that you have all the necessary
tools before you begin this procedure (see
illustration). You should also have plenty of rags
or newspapers handy for mopping up oil spills2Start the engine and allow it to reach
normal operating temperature - oil and sludge
will flow more easily when warm. If new oil, a
filter or tools are needed, use the vehicle to go
and get them, thus warming up the engine oil
at the same time.
3Park on a level surface, and switch off the
engine when it’s warmed up. Remove the oil
filler cap from the valve cover.
4Access to the oil drain plug and filter will be
improved if the vehicle can be lifted on a hoist,
driven onto ramps, or supported by axle
stands.
Warning: DO NOT work under a
vehicle supported only by a
hydraulic or scissors-type jack -
always use axle stands!
5If you haven’t changed the oil on this
vehicle before, get under it, and locate the
drain plug and the oil filter. Note that on some
engines, the oil filter is located on the top left-
hand side of the engine. The exhaust
components will be hot as you work, so note
how they are routed to avoid touching them.
6Being careful not to touch the hot exhaust
components, position a drain pan under the
plug in the bottom of the engine.
7Clean the area around the plug, then
remove the plug (see illustration). It’s a good
idea to wear a rubber glove while unscrewing
the plug the final few turns, to avoid being
scalded by hot oil. Hold the drain plug againstthe threads as you unscrew it, then pull it
away from the drain hole suddenly. This will
place your arm out of the way of the hot oil, as
well as reducing the chances of dropping the
drain plug into the drain pan.
8It may be necessary to move the drain pan
slightly as oil flow slows to a trickle. Inspect
the old oil for the presence of metal particles,
which could give early warning of engine
wear.
9After all the oil has drained, wipe off the
drain plug with a clean rag. Any small metal
particles clinging to the plug would
immediately contaminate the new oil.
10Refit the plug and tighten it securely. Use
a new washer if necessary.
11Move the drain pan into position under the
oil filter.
Canister-type oil filter
12Loosen the spin-off type oil filter by
turning it anti-clockwise with a filter spanner.
Any standard filter spanner will work.
13Sometimes the spin-off type oil filter is
screwed on so tightly that it can’t be easily
loosened. If it is, punch a metal bar or long
screwdriver directly through it, and use it as a
T-bar to turn the filter. Be prepared for oil to
spurt out of the canister as it’s punctured.
14Once the filter is loose, use your hands to
unscrew it from the block. Just as the filter is
detached from the block, immediately tilt the
open end up to prevent oil inside the filter
from spilling out.
15Using a clean rag, wipe off the mounting
surface on the block. Also, make sure that
none of the old sealing ring remains stuck to
the mounting surface. It can be removed with
a scraper if necessary.
16Compare the old filter with the new one,
to make sure they are the same type. Smear
some engine oil on the rubber sealing ring of
the new filter, and screw it into place (see
illustration). Overtightening the filter will
damage the sealing ring, so don’t use a filter
spanner. Most filter manufacturers
recommend tightening the filter by hand only.
Normally, they should be tightened three-
quarters of a turn after the sealing ring
contacts the block, but be sure to follow the
directions on the filter or container.

changing the engine oil and filter

depth, but wide enough to prevent spills
2 Rubber gloves- When removing the drain
plug and filter, you will get oil on your
hands (the gloves will prevent burns)
3 Socket bar - Sometimes the oil drain plug
is tight, and a long bar is needed to loosen
it. The correct-size ring spanner may work
just as well
4 Socket- To be used with the bar or a
ratchet (must be the correct size to fit the
drain plug - six-point preferred)
5 Filter spanner - This is a metal band-type
spanner, which requires clearance around
the filter to be effective. This tool is not
required on all engines.
6 Filter spanner- This type fits on the bottom
of the filter and can be turned with a ratchet
or breaker bar (different-size spanners are
available for different types of filters) This
tool is not required on all engines.
6.7 Using a ring spanner to remove the oil
drain plug
6.16 Lubricate the oil filter sealing ring
with clean engine oil before refitting the
filter on the engine
Frequent oil changes are the
most important preventive
maintenance procedures that
can be done by the home
mechanic. As engine oil ages, it
becomes diluted and contaminated,
which leads to premature engine wear.

Cartridge-type oil filter
17Some models are equipped with a
cartridge-type oil filter. Unscrew the bolt,
remove the cover, and lift the filter out (see
illustrations).
18Compare the new cartridge with the old
one, to make sure they are the same type,
then lower it into the housing.
19Using a clean rag, wipe off the mounting
surface of the housing and cover. If necessary,
renew the rubber O-ring (see illustration).
Smear some clean oil on the O-ring and refit
the cover and bolt. Tighten the bolt securely.
All models
20Remove all tools and materials from under
the vehicle, being careful not to spill the oil
from the drain pan, then lower the vehicle.
21Add new oil to the engine through the oil
filler cap in the valve cover. Use a funnel to
prevent oil from spilling onto the top of the
engine. Pour the specified quantity of fresh oil
into the engine. Wait a few minutes to allow the
oil to drain into the sump, then check the level
on the dipstick (see Section 4 if necessary). If
the oil level is correct, refit the filler cap.
22Start the engine and run it for about a
minute. The oil pressure warning light may
take a few seconds to go out while the new
filter fills with oil; don’t rev the engine while
the light is on. While the engine is running,
look under the vehicle, and check for leaks at
the sump drain plug and around the oil filter. Ifeither one is leaking, stop the engine and
tighten the plug or filter slightly.
23Wait a few minutes, then recheck the level
on the dipstick. Add oil as necessary.
24During the first few days after an oil
change, make it a point to check frequently
for leaks and proper oil level.
25The old oil drained from the engine cannot
be re-used in its present state, and should be
discarded. Oil reclamation centres and some
service stations will accept the oil, which can
be recycled. After the oil has cooled, it can be
transferred into a container for transport to a
disposal site.
7 Power steering fluid level
check

1Check the power steering fluid level
periodically to avoid steering system
problems, such as damage to the pump.
Proceed as follows.Caution: Do not hold the steering
wheel against either stop (full-left
or full-right lock) for more than
five seconds. If you do, the power
steering pump could be damaged.
2On some models, the power steering fluid
reservoir is located on the left side of the
engine compartment, and has a twist-off cap
with an integral fluid level dipstick (see
illustration). Other models use a hydraulic
power steering and brake servo system which
combines the fluid in one reservoir, located at
the right rear corner of the engine
compartment.
3Park the vehicle on level ground, and apply
the handbrake.
4On models with a fluid dipstick, run the
engine until it has reached normal operating
temperature. With the engine at idle, turn the
steering wheel back and forth several times to
get any air out of the steering system. Switch
off the engine, remove the cap by turning it
anti-clockwise, wipe the dipstick clean, and
refit the cap. Remove the cap again, and note
the fluid level. It must be between the two
lines (see illustration).
5On hydraulic servo models, pump the brake
pedal about ten times or until the pedal is firm.
Remove the nut, lift the cap off, and make
sure the fluid is within 6.0 mm of the top of the
reservoir.
6Add small amounts of fluid until the level is
correct (see illustration).
