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).
Loosen intake hose clamp (C).
M62 engine: Remove hose at idle air stabilizer.
Remove air filter housing with mass air flow sensor.
Remove intalte hose from throttle body.

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

< 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
