SUBJECT
: Introduction of new Eberspächer coolant heater
circulating pump
TERMS & CONDITIONS
: This document does not entitle to any reimbursement
APPLICATION:
As from following units onwards, vehicles are factory fitted with a FT6000SC circulating
pump (VH11286525) instead of the previously installed FT5000 circulating pump
(VH11444635).
Model
CX35 MY2020

As the new pump also can be used on vehicles with a FT5000 circulating pump, only the
new pump will continue to be available as a spare part. Please refer to the material list and
step-by-step instructions when replacing a FT5000 circulating pump by a FT6000SC
circulating pump.

Action
Open the exterior access door in front of the left drive wheels.
WARNING!
Carefully slacken the filler cap on the coolant expansion tank and let
the pressure escape. Once all the pressure is off, continue to turn.

Unscrew the filler cap from the expansion tank and remove it.
Install a suitable container under the circulating pump to collect the coolant.
• Close the manual valve in the supply line to the interior heating. To this
end, turn the manual-valve handle clockwise until the handle is
perpendicular to the line.
• Pinch off the coolant-heater outlet line with a special pair of pliers (see
under special tools).

Disconnect the electrical connector of the pump.
Detach both hose clamps at the pump.
Undo the mounting clamp around the circulating pump and remove the pump.
Undo the mounting clamp around the new circulating pump and remove the
bracket. This bracket is not used any more further on in the procedure!
Slide the connections of the new circulating pump in the silicone hoses. Install
the circulating pump with the mounting clamp, but do not yet tighten the
clamp!
Check the alignment of the silicone hose with respect to the coolant heater
and the circulating pump. Adjust when necessary. Tighten the clamps of the
silicone hoses to a torque of 7 ± 0.5 Nm (62 ± 4 in.lbf). Tighten the circulatingpump clamp.

NOTE: Only to be performed when the connector socket of the vehicle wiring
doesn’t match the connector plug of the new circulating pump.
At the coolant heater side, adapt the electric wiring for the circulating pump as
follows:
a. Cut the conducting wires of the existing connector socket. Slide seal
10970038 from the kit over each conducting wire. Strip back the conducting
wires over a distance of 3 to 3.5 mm (0.12 to 0.13 inch).
b. Install connector terminal 10664998 from the kit.
c. Crimp the connector terminal on the conducting wire. To this end, use
crimping tool Tyco PRO-CRIMPER III (Tyco 58583-1) and die (Tyco 585832). For more information, consult Tyco instruction sheet 408-4165.
d. Check the crimping.
Figure 10
e. Introduce the red conducting wire into contact number 1 of the connector
socket, and the brown conducting wire into contact number 2. Check
whether the cable terminal is well secured by pulling the conducting wire
gently. Connect the connector socket to the circulating-pump wiring.

Open the manual valve in the supply line to the interior heating. Remove the
special pairs of pliers in the coolant-heater outlet line.
Check the coolant level in the coolant expansion tank. Top up coolant if
necessary.
Screw the filler cap on the expansion tank.
Go for a ride to warm up the engine (operating temperature).
Stop the engine and check the installation for leaks. Retighten the hose
clamps to a torque of 7 ± 0.5 Nm (62 ± 4 in.lbf). Seal the head of the fastening
screw with a spot of lacquer to indicate that the hose clamp is correctly
tightened. To avoid damage to hose or hose clamp, do not retighten sealed
hose clamps!
Check the coolant level as soon as the installation has cooled down
completely. Top up coolant if necessary.
