WARNING -
Use extreme caution when draining and disposing of engine
coolant. Coolant is poisonous andlethal to humans andpets.
Pets are attracted to coolant because of its sweet smell and
taste. Seek medical attention immediately if coolant is ingest-
---
Working at rear of intake manifold:
Disconnect brake booster vacuum line (A).
Disconnect fuel tank vent line
(6).
Disconnect hoses (C and D) at coolant manifold
- Remove transmission harness support (E).
- Remove oil filter housing assembly from fender:
- Remove oil filter housing mounting fasteners.
Use stiff wire to secure oil filter housing to engine.
NOTE-
Do not disconnect oil lines from filter housing.
4 Disconnect supply and return fuel lines (where applicable) at
or near fuel rail. Plug open fuel lines.
NOTE-
BMW uses three styles of fuel line connections; a slngle use
clamp, a locking fitting that uses special tool
16 7 050 to re-
lease, and a
quiclc release sleeve (arrows) that disconnects
the line when depressed.
WARNING-
Fuel In fuel line is under pressure (approx. 3 - 5 bar or45 -
75 psi) and may be expelled. Do not smoke or worlc near
heaters or other fire hazards. Keep a fire extinguisher
handy. Before disconnecting fuel hoses, wrap a cloth
around fuel hoses to absorb any lealcing fuel. Catch and
dispose of escaped fuel. Plug all open fuel lines.
. Always unscrew the fuel tank cap to release pressure
in the tank before worlcing on the tank or lines.
< Remove air filter housing and mass air flow sensor:
Disconnect mass air flow sensor (A) and
intalte air temper-
ature sensor
(6) electrical harness connectors.
. Remove air filter housing mounting fastener (arrow).

< 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
170 Radi-
ator and Cooling System.
CAUTION-
Do not interchange knoclc sensor harness connectors. Seri-
ous engine damage may result

ENGINES)
WARNING -
Due to risk ofpersonal injur)c be sure the engine is cold be-
fore
beqinning the removal procedure.
Cylinder head removal and installation is a time consuming
repair procedure requiring multiple special service tools.
Read the entire procedure before beginning the repair.
This topic includes the following procedures:
* Cylinder head, removing, M52 TU and M54 engines
Cylinder head, installing,
M52 TU and M54 engines
Cylinder head, removing,

Allow engine to cool before beginning this procedure.
- Disconnect negative (-) cable from battery.
CAUTION-
Prior to disconnecting the battery, read the battery discon-
nection cautions in
001 General Cautions and Warnings.
4 Remove left and right interior ventilation ducts (left side
shown):

CAMSHAFT AND LIFTER REMOVAL
AND ~NSTALLATION
The camshafts can be removed with the cylinder heads
mounted on the engine (in the car).
On 6-cylinder engines there are two different procedures giv-
en, depending on whether the engine is equipped with single
VANOS (M52 engine) or double VANOS
(M52TU or M54 en-
gine).
For V-8 engines, camshaft removal and installation proce-
dures are
only included for the non-VANOS (M62) engine.
Camshaft removal and installation for the
VANOS eq;ipped
V-8 (M62TU) is not covered in this manual.
Special BMW service tools should always be used to remove
and install the camshafts. Removal of the camshafts without
the special tools can result in cylinder head damage and cam-
shaft breakage.

- Remove cylinder head cover studs at rear of cylinder head.
< Place BMW special tool 11 3 240 over camshafts ends and
measure clearance of tool to cylinder head surface.
NOTE-
If the exhaust side of the tool (A) is not flush with the head,
adjust camshaft timing as described below.
Due to flexible sprocket design and VANOS control unit tol-
erances and play, the
intake side of special tool 11 3 240
(B) may be up to 1 mm (0.04 in) above the surface of the
cylinder head. This is normal. Reassemble engine. Other-
wise, adjust camshaft timing as described below.
- Remove double VANOS control unit. See VANOS control
unit, removing
(M52 TU and M54 engines).

hand, and then tighten down uniformly until special tool is in
full contact with cylinder head.
CAUTION-
Male sure all gasket material is removed from face of cylin-
der head. Clean
sealins face and keep free of oil.
