In Part-1 of this two part series, we will remove the electric water pump
and thermostat on a typical late model BMW with the N-series 6-cylinder
engine We will be using an E90 335i, but these general procedures will
apply to most models that have the N engine. See Part-2 for the
The Bentley repair manuals will cover model specific points, torque values
and fill quantities. This DIY will assume that the DIYer has the applicable
Bentley manual for additional references.re.
Since the thermostat resides beside the water pump, and the pump must be
removed in order to replace the thermostat, we highly recommend that the
thermostat be replaced when the pump is replaced. We normally would also
recommend that the coolant hoses be replaced while the system is drained.
However, in these models the only hose that is readily accessible for
replacement is the thermostat to water pump hose. We would suggest
replacing this hose, but the others would require quite a bit of additional
• Water pump
• Water pump mounting bolts
• Thermostat to water pump hose
• Various size hose clamps
• O-ring assembly lubricant
• BMW coolant
• Distilled water
• 3/8" drive E-Torx socket set
• Flex shaft hose clamp driver
• Spill-Free coolant funnel
• Garage Guard absorbent mat
• 3/8" drive sockets, universal joint, extensions and ratchet, 8mm --
• 17mm open-end wrench
• Various flat-head and phillips screwdrivers
• 10-amp battery charger
1) Safely and properly raise and support the front of the vehicle. This
repair task can be performed with the vehicle on jack-stands or using
2) Remove the forward under-chassis splash panel.
3) Disconnect the power steering cooler hose assembly mount on the
passenger side and move the hoses rearward and toward the driver side. Use
a piece of wire or a cable tie to hold the hose assembly out of the way.
4) Remove the two mounting nuts on each swaybar mount and lower the
swaybar. Move the bar toward the rear of the vehicle and tie it up with a
section of wire or a cable tie.
5) Remove the water pump harness plug wiring connector plug.
6) Place the coolant catch pan under the water pump. Using the flexible
hose clamp driver, loosen the hose clamp on the thermostat to water pump
hose (the nipple that is facing the rear of the vehicle) and carefully pull
the hose off the water pump inlet nipple. This will drain most of the
coolant that is in the water pump, thermostat and local hoses.
7) Use the flex driver to loosen the water pump outlet (supply) hose. The
hose nipple points toward the passenger side and is above and to the rear
of the thermostat (look at the new water pump to help locate the nipple and
hose). We cannot remove the hose as it is solidly mounted. We will pull the
water pump from the hose, in step # 13.
8) Remove the two lower water pump mounting bolts, using an E12 Torx
9) Place the coolant drain pan under the forward end of the thermostat and
water pump. Disconnect the radiator to thermostat hose (large plastic hose
elbow at the forward end of the thermostat) by pulling out the locking wire
on the quick disconnect fitting and pulling the fitting off of the
thermostat nipple. Allow the coolant to drain.
10) Remove the two thermostat mounting bolts.
11) Pull the ground cable from the mounting clip that is affixed to the
water pump rib, just forward of the upper water pump mounting bolt. Look at
the new pump and use a light to locate the ground cable and the clip. Pull
the cable out of the clip and push the clip off the rib (toward the
passenger side), using a long screw driver.
