General Tightening fasteners
When tightening the bolts ornuts on acomponent, it is always
good practice to tighten the bolts gradually and evenly to
avoid misalignment or over-stressing any one portion of the
component. For components sealed with gaskets, this meth-
od helps to ensure that the
gasket will seal properly.
WARNING
-
Table a: General bolt tightening torques in Nm (max.
permissible) is
a general reference only The values listedin
the table are not intended to be usedas a substitute for tor-
ques specifically called out in the text or in manufacturer's in-
formation.

quence alternating between opposite sides of the compo-
nent. Repeat the sequence until all the bolts are evenly
tightened to the proper specification.
For some repairs a specific tightening sequence is
neces-
sary, or particular order of assembly is required. Such special
conditions are noted in the text, and the necessary sequence
is described or illustrated. Where no specific torque is listed,
Table
a: General bolt tightening torques in Nm (max. per-
missible) can be used as a general guide for tightening fas-
teners.

Maintenance
Drive axle joint
(CV joint) boots, inspecting
CVjoint protective boots must be closely inspected forcracks
and any other damage that will allow contaminants to get into
the joint.
If the rubber boots fail, the water and dirt that enter
the joint will quickly damage it.
NOTE-
Replacement of the CVjoint boots and inspection of the
joints are described
in 331 Final Drive.
Exhaust system, inspecting
Exhaust system life varies widely according to driving habits
and environmental conditions. If short-distance driving pre-
dominates, the moisture and condensation in the system will
not fully dry out. This will lead to early corrosion damage and
more frequent replacement.
Scheduled maintenance of the exhaust system is limited to
inspection:
* Check to see that all the hangers (arrow) are in place and
properly supporting the system and that the system does
not strike the body.
Check for restrictions due to dents or
kinlts,
Check for weakness or perforation due to rust.
NOTE-
Alignment of the system and the location of the hangers are
described in
180 Exhaust System.
Fuel filter, replacing
The fuel filter is located beneath the center of the car, approx-
imately under the driver's seat.
A protective cover must be
removed to access the filter.
4 Fuel filter for M62 engine (arrow)
- Disconnect battery negative (-) cable
CAUTIOI\C
Disconnecting the battery cables may erase fault codes
stored
in engine control module memory.
WARNING -
Fuel will be expelled forcibly when the filter is removed. Do
notsmoke or work near heaters orother fire hazards. Keep a
fire extinguisher handy

Maintenance
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.

Wheels, aligning
BMW recommends checking the front and rear alignment
once a year and whenever new tires are installed.

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.
Refill and bleed cooling system as described in

sition with BMW special tools as described during VANOS
removal.

Lubrication System
This repair group covers lubrication system troubleshooting
as well as oil pan removal and oil pump replacement.
In 6-cylinder models, removal of the oil pan requires the re-
moval of the exhaust system and some front suspension
components. Those procedures are fully covered in:
180 Exhaust System
210 Clutch
230 Manual Transmission
0 240 Automatic Transmission
310 Front Suspension
320 Steering and Wheel Alignment
NOTE-
Oil change procedure and oil filter replacement are covered
in
020 Maintenance.
CAUTIOG
V8 engines: The oil pump fasteners (including the sprocket
retaining nut) are known to vibrate loose. This can result in oil
starvation and engine failure. Be sure to check oil bolts and
nut tightness whenever the
oilpump is accessible. If any fas-
teners are found to be loose, remove them and reinstall with
Loctite
Band torque to specifications.
Special tools
The engine needs to be properly supported while the front
suspension
subframe is lowered to access the oil pan.
A standard oil pressure gauge may be used for measuring oil
pressure.
