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-

- When oil flow has diminished to an occasional drip, reinstall
drain plug with a new metal sealing washer and torque plug.

- 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.

Maintenance
< Release mass air flow sensor clips (A).
Release upper air filter housing clips (B).
4 Lift air filter upper housing, and remove filter element.
NOTE-
V-8 engine air filter assembly shown in illustration. 6-cylinder
air filter assembly is similar but located at the left front of the
engine compartment.
- On installation, install O-ring for mass air flow sensor into
retaining clips in air filter upper housing.
- Replace air filter and upper air filter housing, and attach
upper air filter housing clips.
Cooling system, checking
Antifreeze raises the boiling point and lowers the freezing
~oint of the coolant. BMW recommends enaine coolantthat is
a 50 150 mixture of distilled water and ethGene glycol-based
antifreeze.
Routine cooling system maintenance consists of maintaining
the coolant level and inspecting hoses. Because the coolant's
anticorrosion and antifreeze additives gradually lose their ef-
fectiveness, replacement of the coolant every three years is
recommended.
CAUJION-
Use only BMWapprovedphosphate-free antifreeze when
filing the cooling system. Use of antifreeze containing
phosphates is harmful to the cooling system.
4 Float in radiator tank indicates coolant level. Inspect while
coolant is cold.
When upper mark on float is level with top of filler neck,
coolant is at minimum allowable level.
When lower mark on float is level with top of filler neck,
coolant is at maximum level.
Hose connections should be tight and dry. Coolant seepage

fluid use and the most-up-to-date information regarding
transmission operating fluids.
The automatic transmission is not equipped with a dipstick.
Therefore, checking the ATF level is an involved procedure
which includes measuring and maintaining a specified ATF
temperature during the checking procedure.
For more complete
ATF service information, including
checking
ATF level and ATF filter replacement procedures,
see
240 Automatic Transmission.
Transmission service, manual
Manual transmission service consists of inspecting for leaks
and checking the fluid. Evidence of transmission leaks is
like-
ly to be seen around the driveshaft mounting flange and at the
bottom of the bellhousing.
NOTE-
For more information on identifying oil
leaks and their
causes, see 230 Manual Transmission and210 Clutch.
