steering reservoir. Push the supplied fitting until
a positive stop is felt. Attach the reservoir to the

the factory fluid return to the reservoir. Attach 1/2"
hose from top of power steering pump to the fitting
installed on the reservoir.

the radiator. Secure with the factory ground strap
bolt located on the radiator core support (see

on the Vortech supplied fuel injectors.
E. Install the new injectors into the fuel rails with the terminals facing outward.
7. POWER STEERING INSTALLATION, cont'd.
NOTE: Complete removal of the fuel rail will aid in injector replacement. Separate the fuel
rail supply line from the rail using springlock disconnect tool.
NOTE: If the vehicle is not equipped with a
power steering cooler, use the
supplied hose mender, 3/8" hose
and hose clamps to extend return
line to reservoir.
