Camshaft Timing Chain
4 Remove VANOS unit:
Remove fasteners from engine support eye.
Remove VANOS mounting nuts (arrows) from cylinder
head. Slide VANOS control unit and metal gasltet off.
NOJE-
The VANOS control unit will contain residual oil. Place
shop towels beneath adjustment unit when removing.
If the VANOS control unit is replaced, or if repair operations
are completed that may change camshaft timing, the cam-
shaft timing must be checked as described in VANOS tim-
ing,
checlcing and adjusting (M52 JU and M54
engines).
CAUJION-
Do not crank the engine with VANOS unit removed.
Piston/valve interference may result.
VANOS control unit, installing
(M52 TU and M54 engines)
< Clean contact edges of cylinder head face and double
VANOS control unit and apply a thin coat of sealing com-
pound (Three Bond
1209 8 or equivalent) to surfaces.
I CAUJION-
. Make sure all gaskel material is removed from lace of
cyl~nder head. Clean sealing lace and keep lree of oil.
Checklocating dowel (A) and dowelsleeve (B) at top of
cylinder head for damage or incorrect installation.
NO
JE -
If the Double VANOS control unit is beino reolaced. be -.
sure to check and adjust camshaft timing, see VA NOS
timing, checking and adjusting (M52 JU and M54 en-
gines).
* If work being carried out has no effect on camshaft timing,
it is not necessary to recheck the timing. It is recommend-
ed, however, that the VANOS operation be checked using
a compatible scan tool once the engine is running.

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.

I Radiator and Cooling System
I I 4 The cooling cassette incorporates cooling coils for various
vehicle systems:
1. Steering fluid cooler
2. Transmission oil
coolel
3. AIC condenser
4 In V-8 cars produced after 911998 (M62 TU engine), the en-
gine radiator is divided into an upper chamber (about 80%)
and a lower chamber (about 20%). The ATF heat exchanger
is coupled to the lower chamber.
On cold engine start-up, the engine coolant is heated more
quicltly than the transmission fluid. Heat from engine coolant
is used to warm up the ATF faster, reducing drag in the trans-
mission and improving fuel mileage.
Once the ATF has reached normal operating temperature,
the ATF heat exchanger acts as cooling device. The lower
20% of the radiator
stays cooler than the upper chamber, so
the ATF is cooled more effectively.
4 M62 TU cooling system ducting at radiator:
1. Coolant distribution housing connection
2. Thermostat connection
3. Water cooled alternator connections
4. Transmission fluid heat exchanger connections

Manual Transmission
Manual transmissions installed in the 5 Series are normally
filled with a "Lifetime" manual transmission fluid
(BMW MTF
LT-I) and do not require periodic fluid changes. Transmis-
sions filled with MTF LT-I lifetime oil are identified with a yel-
low label near the transmission fill plug labeled "Lifetime Oil
MTF-LT-1".
Transmission fluid level, checking
- Drive vehicle for a few miles to warm transmission.
- Raise and safely support vehicle to access transmission
filler plug.
CAUTION-
Make sure the car is stable and well supporfedat all times.
4 Remove side filler plug (B). Insert finger into hole to check
fluid level. If fluid level is up to bottom of filler hole (finger is
wetted by transmission fluid), level is correct.
NOTE-
* Check and fill transmission with car on level surface.
5-speed transmission shown in illustration. 6-speed trans-
mission is similar.
- Install and torque filler plug.
Tightening torque

to transmission case SO Nm (37 it-lb)
Transmission fluid, replacing
- Drive vehicle for a few miles to warm transmission.
- Raise and safely support vehicle to access drain plug.
CAUTION-
Make sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed
for the purpose.
A floor jack is not adequate support.
Check that the
fill plug is not seizedprior to draining
transmission fluid.

Differential oil level, checking
The E39 differential is filled with lifetime oil that ordinarily
does not need to be changed. BMW recommends using only
a specially formulated synthetic gear oil
(SAF-XO) that is
available through an authorized BMW dealer parts depart-
ment. For additional information on this lubricant and any oth-
er lubricants that may be compatible, contact an authorized
BMW dealer service department.
< Check rear differential oil level at filler plug (arrow).
- Check lubricant level with car on a level surface:
Level is correct when fluid just reaches edge of filler hole.
If necessary, top up fluid.
* Replace filler plug sealing ring.
Install and tighten oil filler plug when oil level is correct.
NOTE-
Use either a 14 mm or 17 mm Allen socket to remove the
drain plug.
If car is raised in the air. it should be level when
checkino " or filling final drive fluid level.
