SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O. #) from the California Air Resources
Board (C.A.R.B.) making it legal for street use on pollution-controlled motor vehicles in all 50 states. To assist you with
emissions equipment certification, we have included a silver fan shroud decal to help testing personnel verify that this part
is a legal replacement part on the vehicle for which it is cataloged. The adhesive-backed decal should be affixed to your
fan shroud next to the existing emission and engine specification decal. Do not cover your original equipment specification
decal with the Edelbrock fan shroud decal.
WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty on your Pro-Flo header.
Those products can cause excessive heat and moisture build up resulting in corrosion and early failure of the system.
DISASSEMBLY:
1. Disconnect battery negative cable from battery.
2. Raise vehicle and support with jackstand.
3. The use of penetrating oil when removing and the use of anti-seize compound when installing nuts and bolts will
prevent the possibility of broken or stripped nuts and bolts.

5. Remove O2 sensor (if applicable) being careful not to destroy or rupture the unit. Warning: Do not clean this unit
in any cleaning solvents and do not rupture wire.
