Intercooler Coolant Fill Procedure
Your ROUSH
®
F-150 is equipped with a single-core, air-to-water intercooler system with an electric water pump.
This provides a cooler air charge to the cylinders, allowing your engine to develop more power.
1) Add coolant until it is one inch (2.54 cm) from the top of the intercooler reservoir bottle.
2) Turn the ignition key to the “ON” position to turn on the intercooler pump and purge any trapped air in the
system. Repeat steps 1 and 2 until the reservoir stays at the full mark.
