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 tight-
ness. 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. Start the engine and allow to idle a few minutes,
then shut-off.
E. Recheck to be sure that no hoses, wires, etc. are
near exhaust headers or moving parts. Look also
for any signs of fluid leakage.
F. PLEASE TAKE SPECIAL NOTE: operating the
vehicle without ALL the subassemblies completely
and properly installed may cause FAILURE OF
MAJOR COMPONENTS.

NOTE: Check to see that CAC coolant is flowing
through the surge tank. If coolant is not
flowing, remove the 3/4” rubber hose from
the side of the CAC and apply light suction
in an attempt to pass any trapped air in the
system. Reconnect the hose and recheck
coolant flow.
