How to Prime the Edelbrock E-Force Intercooler Systems.
The electric water pump used on this Edelbrock E-Force Supercharger System has a built-in
micro-processor that will vary pump cycle speed when air bubbles are present in the system. If
a significant amount of air is trapped in the system, the pump may cycle at a slower speed and
pulsations are likely to occur resulting in poor cooling performance.
For the best result, it is highly recommended to use a Radiator Cooling System Vacuum Purge and Refill Kit to properly
evacuate the air from the intercooler system before filling with a 50/50 mixture of coolant and distilled water. If one is not
available, the following procedure will be adequate.
1. Using the Lisle 24680 Spill-Free Funnel, or equivalent, secure the appropriate filler neck adapter to the surge tank.
2. Attach the funnel and fill with a 50/50 mixture of coolant and distilled water until the funnel is half full.
3. Turn the ignition to the ON position and listen for the pump’s electric motor to cycle. Air bubbles will begin to purge
from the system as the coolant level drops. Add coolant to the funnel as necessary. NOTE: Do NOT let the coolant level
in the funnel run empty as this may introduce air into the system.
4. To build more pressure in the intercooler system, try squeezing the intercooler hoses while the pump is cycling.
Building pressure in the system will help purge the trapped air from the intercooler system.
5. Cycle the ignition OFF and wait a few seconds for the pump to come to a stop.
6. Cycle the ignition ON again and repeat until the sound of the electric pump is continuous without any pulsation. NOTE:
During water pump start-up, it is normal for a slight pulsation to occur. Once the pump has reached its maximum cycle
speed, no pulsations should be present.
7. Periodically inspect the water pump flow after a few drive cycles and re-fill the intercooler system as necessary.
8. Several drive cycles may be required to completely purge the air from the intercooler system. During a drive cycle, the
intercooler system will build up pressure as the supercharger temperature increases. Any residual air trapped in the
system will gradually bleed out of the surge tank as the system reaches a pressure above 5psi.
WARNING: Always avoid removing the surge tank cap when the engine is hot. The hot coolant is under
pressure and may spray out causing burns.
