I Radiator and Cooling System
Common cooling system faults can be grouped into one of 4
categories:
Cooling system
lealts
Poor coolant circulation
Radiator cooling fan faults
Electrical/electronic faults
Cooling system inspection
- Check that coolant pump drive belt tensioner is functioning
properly and that belt tension is correct. Belt tensioner sys-
tems for the different models are shown in
020 Maintenance.
- Check condition of coolant pump drive belt.
- Checlc coolant hoses for cracks or softness. Checlc clamps
for looseness. Check coolant level and check for evidence of
coolant
lealts from engine.
- Check that radiator fins are not blocked with dirt or debris.
Clean radiator using low-pressure water or compressed air.
Blow outward, from engine side out.
- To check coolant pump:
Remove mechanical cooling fan. See Mechanical
(vis.
cous clutch) cooling fan, removing and installing.
Remove drive belt from coolant pump pulley. See
020
Maintenance.
Firmly grasp opposite sides of pulley and check for play in
all directions.
Spin pulley and check that shaft runs smoothly without
play.
NOTE-
The coolant provides lubrication for the pump shaft, so an oc-
casional drop of coolant
lealing from the pump is acceptable.
If coolant drips steadily from the vent hole, replace the pump.
- At normal engine operating temperature, cooling system is
pressurized. This raises boiling point of coolant.
Leaks may
prevent system from becoming pressurized. If visual evi-
dence is inconclusive, pressure test cooling system as de-
scribed later to help pinpoint hard-to-find leaks.
- If cooling system is full of coolant and holds pressure:
- Use an appropriate scan tool to interrogate engine control
module (ECM) for radiator fan or DME control circuit faults.
Checlc for loose or worn drive belt.
0 Test for failed thermostat or coolant pump impeller. Some
pumps may be fitted with plastic impellers.

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
Transmission drain or fill
plug
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.

Carefully pry out selector shaft oil seal with BMW special tool
23
0 210, or with a narrow seal remover or small screwdriver.
Coat new selector shaft seal with transmission fluid. Drive
new seal in flush with housing. Use
BMW special seal instal-
lation tool
23 0 220 or equivalent and a soft-faced (plastic)
hammer.
- Remainder of installation is reverse of removal, noting the fol-
lowing:
Install driveshaft using new
loclc nuts.
Check transmission oil level, topping up as necessary.

I Automatic Transmission Automatic transmission fluid (ATF)
The E39 automatic transmission is filled with either Dexron Ill
ATF or Texaco 80728, a life time oil.
CA UTIOI\C
Use only the transmission fluid that is approved for use by
BMW All other fluids will cause non warrantable transmis-
I sion damage.
Mixing different types of transmission fluids will lead to
transmission failure.
NOTE-
The type of transmission lubricant used can be found on a
stickeron the transmission pan. Dexron
111ATF (blacksticker)
reads "ATF-Oil': Special life time oil (green sticker) reads
'Life-Time Oil': If in doubt, consult an authorized
BMW dealer
for alternate fluid use and current information regarding
transmission operating fluids.
ATF level, checking
Check ATF level if there is evidence of a leak, a complaint re-
lated to fluid level or afler transmission repairs.
The automatic transmission is not equipped with a dipstick.
Checking the ATF level requires that the transmission be at
operating temperature during the checking procedure.
NOTE-
Vehicle must be level throughout tests
- Drive vehicle to warm up ATF to operating temperature.
- Connect BMW diagnostic scan tool DiSplus, MoDiC, GTI or
equivalent to determine transmission oil temperature.
ATF level checking
Fluid temperature
30' - 50°C (85' - 120" F)
- With engine running, switch on air conditioning to increase
engine idle speed.
- Apply parking brake.
- While applying foot brake firmly move gear shift selector
lever through
all gear positions, pausing in each gear briefly.

- Blow out oil cooler lines with low-pressure compressed air
and flush cooler with clean ATF twice before reattaching lines
to transmission.
CA UTIOG
Wear safety glasses when worling with compressed air:
@ Do not reuse ATF used for flushing.
- Remainder of installation is reverse of removal, noting the fol-
lowing:
Reinstall driveshafl using new nuts.
Install new sealing washers on transmission cooling line
banjo bolts.
Install new O-rings on transmission cooler lines, where
applicable.
Inspect engine drive plate (flywheel) for cracks or elongat-
ed holes. Replace
if necessary.
Be sure bellhousing alignment dowel sleeves are located
correctly. Replace damaged sleeves.
Checlc to be sure torque converter is seated correctly in
transmission during final installation.
Use
BMW special tool 24 2 300 to align three mounting
tabs on torque converter with indentations on drive plate
(flywheel).
Fill transmission with clean ATF until oil level is even with
fill hole. Then check fluid level as described earlier.
Adjust gearshift mechanism. See
250 Gearshift Linkage.
NOTE-
In order to avoid difficulties in transmission removal at a fu-
ture time, use washers with Torx-head mounting bolts.
