Charge Air Cooling System (LT4)
This kit contains a charge air coolant pump. The pump is controlled by the Chevrolet Performance Parts engine control system.
The charge air cooling systems function is to reduce the temperature of the air charge that is heated during the supercharging
process which improves the efficiency and performance of the powertrain. The charge air cooling system is an air-to-coolant
system that uses a separate charge air cooling radiator. An electric pump is used to flow coolant from the charge air cooler
(vehicle specific), through the supercharger, then back to the charge air cooler where the cycle repeats.
Start-up and Break-in Procedures
Use only engine oil licensed to the dexos1® specification of the proper SAE viscosity grade. AC Delco dexos1 Synthetic Blend
is recommended. For track events or competitive driving, use Mobil 1® 15W-50 engine oil. Safety first, if the vehicle is on the
ground, be sure the park brake is set, the wheels are chocked and the car cannot fall into gear. Verify everything is installed
properly and nothing was missed.
This engine assembly needs to be filled with oil. After installing the engine, ensure the crankcase has been filled with the
appropriate motor oil to the recommended oil fill level on the dipstick. This crate engine require a special oil meeting dexos1.
Also check and fill as required any other necessary fluids such as coolant, power steering fluid, etc.
The engine should be primed with oil before starting. Install an oil pressure gauge (there is a plugged port that can be used to
mechanically measure oil pressure and used to force prime the system using Kent More J45299 priming tool, see Figure 9/10).

If the priming tool is not use then disconnect the ignition control system (removing power from the ignition control module is
generally recommended, but check your ignition control system information for additional details).
