CTS-V LSA intercooler radiator kit with fans
Stainless Steel Constant tension worm gear clamp
Spring clamp
Thank you for purchasing the Lingenfelter Performance Engineering (LPE) VariMax CTS-V high flow intercooler
pump upgrade kit. This kit is intended to bring the intercooler flow rate of the CTS-V up to the same flow
rate as the ZL1 Camaro. As you can see in the chart provided on the next page, the factory CTS-V intercooler
pump flows 25% less fluid per minute than the factory intercooler pump in the ZL1 Camaro. The VariMax
intercooler pump, also shown in the chart on the next page, provides the same flow rate as the factory ZL1
Camaro intercooler pump. This kit is designed to provide easy mounting of the intercooler pump through a
custom mounting bracket. Finally, this kit features a plug & play harness with an additional connector to allow
for easy wiring of an optional manual override switch. Installing a manual override switch could be used to
circulate the intercooler fluid between runs to help cool the fluid in drag racing applications.
The Varimax CTS-V high flow intercooler pump is a DC brushless pump that has a soft start. The
Varimax pump can accept a PWM speed control signal, but the way the CTS-V is wired the pump
will always run at full speed. Being a soft start pump, the pump ramps up to full speed over time.
A DC brushless pump does not have the initial current spike that a traditional pump will have.
Read the entire instruction manual before beginning installation. Many of the stock parts will be
used in reassembly.
When referencing the side of the vehicle, the driver side of the vehicle is considered the left side
and the passenger side of the vehicle is considered the right side of the vehicle.
Due to the thermal expansion of rubber coolant hoses, LPE does not recommend using worm
gear clamps to clamp the hoses to the intercooler pump. Because worm gear clamps do not
apply constant tension to the hoses, the hoses can leak when exposed to cooler temperatures.
LPE recommends the use of the OEM constant-tension clamps or spring clamps as superior
alternatives to the standard worm gear clamp.

Note: Some pictures show that the engine was removed from the vehicle. You do not
need to remove your engine to install the Lingenfelter Performance Engineering (LPE)
VariMax CTS-V high flow intercooler pump.
1. If you have been driving the vehicle, make sure to
allow a couple hours for the engine to cool down
before beginning installation.
2. Raise the vehicle with a vehicle hoist or a jack
and jackstands. Be careful to follow the GM lifting
procedures for the CTS-V.
3. In order to make it easier to drain the fluid from the
system, remove the cap from the intercooler fluid
reservoir. The reservoir is located at the back of the
engine on the passenger side near the fire wall.
Page 4
4. Locate the intercooler pump. This pump should be
located just inside of the passenger side engine
brace, just behind the radiator.
5. To drain the intercooler system of coolant, using a
3/8” square drive extension, remove the drain fitting
from the passenger side of the intercooler radiator.
Have a drain pan positioned to catch the fluid.
Inspect the fluid. If it is normal in appearance, it can
used again. If it is discolored then we recommend
flushing the system of the old fluid and using all new
intercooler fluid.
6. Using a pair of hose clamp pliers, loosen the hose
clamp on the inlet hose. Disconnect the inlet hose
from the intercooler pump and let both the pump
and the hose drain into a bucket.
Note: If the hose is difficult to remove, you can spray
silicone in between the hose and the inlet of the
pump.
7.
Using a pair of hose clamp pliers, loosen the hose
clamp on the outlet hose. Disconnect the outlet hose
from the intercooler pump and let both the pump
and the hose drain into a bucket.
Note: If the hose is difficult to remove, you can spray
silicone in between the hose and the outlet of the
pump.

8. Locate the connector on the rear of the intercooler
pump body and disconnect it by pinching the metal
clips while pulling away from the pump.
9. Using a 13mm socket, ratchet, and extension if
necessary, remove both M8 nuts that hold the Adel
clamps to the factory mounting bracket.
10. Remove the intercooler pump from the mounting
bracket, which will expose both M8 mounting studs,
as well as the end of the wire loom retaining clip.
11. If you did not do so already, disconnect the harness
connector that is located behind the factory
intercooler pump mounting bracket.
Page 6
12. Using hose plugs, cap off the intercooler hoses.
13. Using a small pry tool or flat head screwdriver,
remove the wire loom retaining clip from the
factory mounting bracket. The location of the wire
loom retaining clip is shown by the red arrow in
the adjacent illustration. Next, remove the factory
intercooler pump harness from the vehicle.
14. Install the supplied wire loom retaining clip onto the
supplied VariMax intercooler pump wiring harness
by sliding it onto the connector, as shown by the red
arrow in the adjacent illustration.
15. If a manual override switch is not being installed,
install the plug seal into the end of the supplied
connector, and close the retainer clip on the
connector. Then install the connector onto the single
connector that is on the harness.
Page 7
16. If installing a manual override switch, crimp the
female terminal onto 16 gauge wire and make sure
the seal is crimped under the large tangs on the
terminal. Then push to seat the terminal into the
connector and close the retaining clip. Run the wire
to a switch rated for at least 15 amps, and connect
that switch to either an always hot, or accessory
power source that uses a 15 amp fuse.
17. Install the new VariMax intercooler pump harness
onto the factory intercooler pump mounting bracket
by inserting the end of the wire loom retaining clip
back into the bottom hole of the mounting bracket.
Make sure to push the retaining clip through the
hole as far as you can to ensure that the harness is
securely fastened to the vehicle.
18. Plug the 2-way harness connector into the new
VariMax intercooler pump harness.
19. Install the Varimax pump bracket (PN: XX000540002) onto the Varimax Pump as shown. Use an
8mm wrench and a 4mm (or 5/32”) Allen wrench to
secure the bracket to the pump.
Note: The bracket shown in steps 20-22 does not
show the revision for the Christmas Tree fastener.
The bracket fits over the Christmas Tree fastener
without any modifications.

Order of Assembly is as follows:
screw -> washer -> clamp -> bracket -> nut
20. Place the spacers onto the two studs that protrude
out of the factory intercooler pump mounting
bracket.
21. Place the VariMax intercooler pump bracket onto the
two studs that protrude out of the factory intercooler
pump mounting bracket as shown. Using a socket
wrench and a 13mm deep socket, secure the Varimax
intercooler pump bracket to the factory intercooler
pump mounting bracket.
22. Plug the 4-way connector from adapter harness
(PN: XX05102-0015) into the back of the VariMax
intercooler pump. You should hear an audible “click”
when the connector locking mechanism is fully
engaged.
Page 9
23. Remove the hose plug from the outlet hose.
24. Work the outlet hose onto the intercooler pump
nipple that is pointing upward. Then, using a pair
of hose clamp pliers, position and secure the hose
clamp on the outlet hose.
25. Remove the hose plug from the inlet hose.
26. Work the inlet hose onto the intercooler pump nipple
that is pointing towards the front of the vehicle.
Then, using a pair of hose clamp pliers, position and
secure the hose clamp on the inlet hose.
Page 10
27. Verify the inlet and outlet hoses from the pump are
not touching the fan shroud.
FAN SHROUD
28. Fill the intercooler system using a 50/50 mixture
of DEX-COOL antifreeze and clean, drinkable water
until the coolant level reaches the top of the cold fill
range on the reservoir. The location of the reservoir
is shown by the yellow arrow in the adjacent
illustration.
NOTE - if the pump sound level changes or is erratic,
you likely have air trapped in the system and need to
bleed the system and make sure it is properly filled
with coolant. It is very important to get all of the air
out of the system.
Installation of the Lingenfelter CTS-V VariMax high flow intercooler pump kit is now complete!
NOTE: The Varimax CTS-V high flow intercooler pump is a DC brushless pump that has

Pump Warning 4 - 6%
A) Low Back EMF (possible impeller blockage) – Stops forward rotation, reverses the motor for 2.5s to
clear potential impeller blockage, and then restarts.
B) High temperature warning (Temperature is close to operational thermal limit)
Motor slows to 2500RPM, in an attempt to cool. The lower RPM lowers the current which in turn, lowers the
pump self heating characteristic. The pump exits this mode once the temperature (warning condition) has
moved below the full operation temperature limit (timing is unspecified).
C) Over-Current during normal operation (possible problem) - If an over-current occurs during normal
operation the pump is stopped. After a 10 second wait, the pump will attempt to restart.
Pump Fault 88-90%
A) Impeller Blockage (sustained Low back EMF) - If 5 consecutive blockage events (see Pump Warning “A”
low back EMF) have occurred, this mode is entered. The pump will stop. The pump will not restart until a
power re-cycle occurs.
B) Over Temperature - The high temperature operation limit is exceeded. The pump stops and stays in this
state until the unit cools.
C) Over-Current at startup - if an over-current occurs during initial activation of FETS, the pump is stopped
until a power re-cycle occurs.
D) Over-Current during operation (sustained over-current during operation) - After 5 consecutive cycles of
“Over-Current during normal operation” (See Pump Warning “C”), the pump is stopped until a power re-cycle
occurs.
