Notes:
• Read all the instructions before beginning the installation process in order to make sure you have
all of the tools and equipment needed and that you feel comfortable performing the installation.
• Be careful on the torque specifications. Some torque specifications are in pound feet (LB-FT) and
others are in pound inches (LB-IN).
• Be sure to save all of the parts you remove from the vehicle. Many components will be re-used
during the installation of this system.
• Be careful not to damage any components while removing them from the vehicle. Some parts are
can’t be purchased by themselves from GM and must be purchased as part of an entire assembly.
• Some steps will require two people.
• Estimated installation time is 4 to 6 hours.
Thank you for purchasing the Lingenfelter Performance Engineering (LPE) Cadillac CTS-V High
Capacity Intercooler Radiator system. This kit is designed to improve the performance of the engine
by reducing the charge air temperature at all RPM ranges and duty cycles.
This system features a heat exchanger with a back to front double pass coolant flow configuration
designed to optimize heat transfer by maintaining the highest temperature difference between the
incoming airflow and the intercooler fluid across the entire fluid path. The system also includes two
temperature controlled puller type fans to increase air flow across the intercooler, especially when
stopped or under low speed conditions. These fans feature low and high speed mode and are
temperature controlled based on the intercooler fluid temperature itself. This reduces fan noise when
they are not needed and increases fan durability.
The LPE intercooler radiator has been designed and tested to make sure it is compatible with the
stock as well as aftermarket intercooler pumps. This intercooler radiator provides increased surface
area and coolant volume yet has the same coolant flow restriction as the OEM radiator so as not to
hurt pump performance.
This kit is designed for 2009-2014 Cadillac CTS-V’s with the LSA engine and replaces the OEM
intercooler radiator. Additional improvements in charge-air temperatures can be obtained if you also
install the optional LPE CTS-V Varimax high flow intercooler pump kit (PN L330030709). This kit is
a designed to be a direct replacement for the stock CTS-V and includes a high flow DC brushless
intercooler pump that provides roughly 25% more flow than the stock CTS-V pump, bringing the
CTS-V up to the same intercooler pump flow as the ZL1 Camaro.
For applications that require an even higher flowing intercooler fluid circulation pump we recommend
the Stewart-EMP WP29 pumps (part # ST-E2512A or ST-1030002107).
WARNING: Due to the high flow rate of the Stewart EMP WP29 water pumps, changes to the
circulation system must be made in order to reduce pump inlet restriction if you want to use one of
these pumps. A custom reservoir must be made with 1” fittings and hose going from the reservoir
to the pump inlet. The reservoir must be mounted above and close to the pump and have as few
bends as possible in the hose from the reservoir to the inlet of the pump. Failure to perform these
changes will result in significantly reduced pump flow and potential pump failure. Due to the engine
compartment configuration of the CTS-V such a coolant reservoir would likely need to be mounted in
the trunk (along with the pump being mounted in the back of the vehicle).
