10. FINAL ChECk
A. If your vehicle has gone over 15,000 miles
since its last spark plug change, you will need
to change the spark plugs now before test
driving the vehicle.
B. Check all fitting, nuts, bolts and clamps for
tightness. Pay particular attention to oil and
fuel lines around moving parts, sharp edges
and exhaust system parts. Make sure all
wires and lines are properly secured with
clamps or tie-wraps.
C. Check all fluid levels, making sure that your
tank(s) is/are filled with 91 octane or higher
fuel before commencing test drive.
D. (For Internally Lubricated V-3 Units Only)
This supercharger has been factory pre-filled
with special Vortech synthetic lubricant. Oil
does not need to be added to a brand new
unit; however a fluid level check should be
performed.
Prior to operating the supercharger on the
vehicle and after installation onto the vehicle:
Remove the factory installed flat-head brass
shipping plug (not the dipstick) from the top
of the supercharger case. Replace the sealed
shipping plug with the supplied “vented” plug.
Do not operate the supercharger without it.
Check the supercharger fluid level.
Fluid level checking procedure:
1. Ensure that the .06” copper sealing
washer is located on the dipstick base.
2. Thread the clean dipstick into the super-
charger unit it seats.
3. Once the dipstick has seated, remove
the dipstick from the unit. Fluid should
register in the crosshatched area on the
dipstick.
4. DO NOT OVERFILL!!! Drain excess fluid
the unit if it is above the maximum level
on the dipstick.
NOTE: Once the Re-flashed ECU and TCM are received back from Vortech, reinstall them in the reverse order removed.
Take care not to damage the harness connectors or ECU/TCM connection pins. Re-secure the washer fluid/cool-
ant reservoir assembly.
WARNING: Do not attempt to operate the vehicle
until all components are installed and
all operations are completed including
the final check.
