Tesla Model S: Reservoir Assembly - Coolant (Remove and Replace)
Warning: If the 12V power supply is disconnected, do
not attempt to open any doors with door glass in closed position.
Failure to follow this instruction could result in door glass
shatter.
Note: Before disconnecting the 12V power supply,
ensure that the driver's door window is fully open. Failure to
follow this instruction could result in vehicle lockout.
Removal
- Remove the LH front upper wheel arch liner (RH for RHD) (refer
to procedure).
- Disconnect 12V power.
- Rear wheel drive (RWD): Refer to
procedure.
- Dual Motor: Refer to procedure.
- Remove the underhood storage unit (refer to procedure).
- Disconnect the harness connections (x2):
- Powertrain coolant pump connector (red arrow)
- Coolant level sensor connector (yellow arrow)
- Clamp the hose from the reservoir to the 4-way valve. Ensure
that the clamp is placed just below the spring clamp on the
reservoir.
- From the LH wheelwell (RH for RHD), clamp the hose from the
powertrain coolant pump to the rocker hose. Ensure that the clamp is
placed just outside of the spring clamp.
- Remove the reservoir cap.
- Siphon the coolant from the reservoir into a container.
- For RHD vehicles: release the bolt that secures the coolant
reservoir upper bracket to the strut brace (torque 5 Nm).
- Release the 1 nut that secures the coolant reservoir upper
bracket (torque 5 Nm).
- Release the bolts (x2) that secure the coolant reservoir to the
crossmember (torque 5 Nm).
Note: RHD vehicles have a refrigerant pipe routed
very close to these bolts. Use a long extension to remove
the bolts.
- Release the 2 fasteners that secure the coolant reservoir
bracket.
- Release the spring clamps (x2).
Caution: Do not remove the clamps that were placed on
the hoses in steps 5 and 6.
- Remove the coolant reservoir and powertrain coolant pump
assembly from the vehicle.
Caution: Plug the hoses to prevent ingress of moisture
or dirt.
- For RHD vehicles, remove the bolt that secures the bracket to
the pump (torque 4 Nm).
- Position the reservoir and pump assembly over a container to
catch any coolant that is spilled in the next step.
- Release the spring clamp that secures the hose to the coolant
pump assembly.
- Clean up any spilled coolant.
Installation
Installation procedure is the reverse of removal, except for the

General
Avoid getting grease on electrical components and connectors. Grease
collects dirt, which can cause electrical tracking (short-circuits) or
high resistance.
