Attach the negative cable to the battery and tighten using an 8mm wrench.
100.
Install the supplied 50-state legal sticker (when applicable) to the hood next to the factory emissions sticker or visible
location in engine compartment. Use light amount of acetone to clean surface before installing.
101.
Attach the “91 OCTANE OR HIGHER” decal to the gas tank fill cap or door.
102.
Using a Lisle 24680 Spill-Free Funnel, or equivalent, secure the appropriate filler neck adapter to the filler neck.
103.
Attach the funnel and fill with a 50/50 mixture of coolant and distilled water until the funnel is half full. Whipple
recommends Ford Motorcraft or Zerex G-05 to match the stock color. Whipple also recommends 1 bottle of Red Line
Water Wetter or equivalent. Note: The Whipple IC system is compatible with all common types of antifreeze.
Never
use tap water, this will cause corrosion and destroy the system
. The system takes approximately 2 gallons of fluid.

Turn the ignition to the ON position, after a brief delay, the electric pump motor will cycle. Air bubbles will begin to
rise to the filler tee as the coolant level drops, continue to fill while pump is running. Once its done filling, turn the
ignition key OFF, the level will drop, top off with fluid. Reinstall filler cap and turn the ignition ON and let run for 15
seconds. Turn key OFF, remove cap to release air. Repeat until the filler tee holds between minimum and maximum
fill level with key OFF. 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 push the trapped air from the intercooler system to the
filler tee. It also helps to lift the filler neck 4”-8” higher than its mount to help purge the air. NOTE: Do not let the
coolant level in the funnel run empty as this may introduce more air into the system.
The electric water pump used on the Whipple SC 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 lower 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 the 50/50 mixture of coolant
and distilled water. If one is not available, the following procedure will be adequate.
