continue to operate as designed. Extending the replacement
interval may void the emission control warranty coverage.
See
180 Exhaust System for information on replacing the
oxygen sensors.
Tightening torque
Oxvoen sensor to exhaust
manifold 50 Nrn (37 ft-lb)
NOTE-
A special soclet for replacing the oxygen sensor is available
from most automotive parts stores. The soclet has
a groove
cut down one side to allow the sensor to be installed without
damaging the wire harness.
Power steering fluid, checking level
The power steering system is permanently filled and does not
have a drain. Routinely adding ATF is not required unless the
system is leaking.
4 To check power steering fluid level in fluid reservoir:
Park car on level ground with engine off.
Level is correct
if it is between MlN and MAX marks on
dipstick.
If level is below
MlN mark, add fluid to reservoir to bring
level up.
* Hand-tighten reservoir cap.
Power steering fluid
Dexron
1iiO ATF or equivalent
Spark plugs
E39 models through model year 1998 were equipped with
spark plugs with two electrodes. These are gapped to
0.7 mm
(0.028 in) by the manufacturer and are not adjustable.
Starting with 1999 models, long life spark plugs with
3 or four
electrodes were used. These can be retroactively fitted to
earlier
models. The recommended spark plug replacement
interval
forthese is 100,000 miles.The electrode gap in these
spark plugs is not adjustable.

1 Maintenance
- When replacing fuel filter:
Use appropriate hose clamping device to clamp off filter
inlet and outlet hoses to lessen fuel spillage.
Loosen center clamping bracket and hose clamps on
either end of filter.
Note arrow or markings indicating direction of flow on
new filter.
Install new filter using new hose clamps
- Drain fuel filter from inlet side into a container and inspect
drained fuel.
Checlc for rust, moisture and contamination.
I - I < If fuel filter is equipped with fuel pressure regulator:
I 2 / Remove vacuum hose (1)
Pull out locking clip (2).
- Remove fuel pressure regulator (3).
Install pressure regulator in new filter.
Clean thoroughly around the filler connections before
removing them.
After assembly, check filter connections carefully for
I
I lealcs before installing cover.
NOTE- ~-
Additional informarion about the fuel filler assembly is in 160
Fuel Tank and Fuel Pump.
Fuel tank and fuel lines, inspecting
lnspectthe fuel tank, fuel lines, and fuel system fordamage or
lealts. Checlc for fuel lealts in the engine compartment or fuel
odors in the passenger compartment. Check for any evapora-
tive emissions hoses that may have become disconnected,
checking carefully at charcoal canister and evaporative emis-
sions purge system. See
130 Fuel Injection and 160 Fuel
Tankand Fuel Pump for component locations and additional
information.
WARNING-
When checlcing for fuel leal(s, the engine must be cold. A hot
exhaust manifold or exhaust system could cause the fuel to
ignite or explode causing serious personal injury Ventilate
the work area and clean up spilled fuel immediately.

- Installation is reverse of removal, noting the following:
Replace all gaskets. O-rings and seals.
Use new fuel injector seals
Check that engine drive belts properly engage pulley
grooves.
Inspect O-ring seal between mass air flow sensor and air
filter housing. To facilitate reassembly, coat seal with acid-
free grease.
Change engine oil and filter and
check all other fluid levels.
See
020 Maintenance.

Remove polyribbed A/C compressor belt:
Mark direction of belt travel if belts are to be reused.
Loosen bolts
(A).
Turn adjusting lug (B) clocltwise to release belt tension.
Working beneath car, remove power steering pump and air
conditioner compressor. Suspend from body using stiff wire.
Remove exhaust manifolds. See
180 Exhaust System.
< lnstall engine lifting device (BMW 11 0 000 or equivalent) to
front and rear engine supports and raise engine until it's
weight is supported. Detach engine mounts.
a Watch carefully for hoses and electrical wires that might
snag.
- installation is reverse of removal:
Replace all gaskets, O-rings and seals.
V-8 engine mounts have two sets of mounting holes. E39
cars use front most mounting holes.
* On cars with automatic transmission, use new O-rings at
ATF cooler lines.
Use new alignment sleeves when installing transmission.
Be sure engine drive belts properly engage pulley grooves.
When installing belt, preload tensioner to stop (toward
belt), then tighten tensioner clamping nut.
lnstall front exhaust pipes using new gasltets and copper
paste and new mounting hardware. See
180 Exhaust
System.
Change engine oil and filter. Check all other fluid levels as
described in
020 Maintenance.

WARNING -
Use extreme caution when draining and disposfng of eng~ne
coolant. Coolant is poisonous and lethal to humans andpets.
Pets are attracted to coolant because of its sweet smell and
taste.
Seek med~cal attention immediately if coolant is ingest-
ed.
