IMPORTANT: If vehicle is equipped with a power steering cooler (LS1 only), outlet hose and cooler hose (if replacing) must be removed from the power steering cooler as the cooler is installed in the outlet hose (return back to reservoir).


INSTALLATION PROCEDURE





1. Install outlet hose to reservoir (LS1 with cooler shown, remote-mount reservoir on L36). (Pump mounted on LS1, body mounted on L36)

IMPORTANT: Inlet and outlet hoses must be oriented so as adequate clearance is maintained between both hoses and surrounding components to prevent chafing. Use minimum clearance of 12 mm (.47 inch). The outlet hose must not be twisted during installation. Do not bend or distorx inlet and outlet hoses to make installation easier. Failure to follow these procedures could result in component damage.





2. Install inlet hose fitting (3) to pump (1) (L36 shown, LS1 similar).
3. Install the power steering pump pulley. Refer to Power Steering Pulley Replacement for L36 V6 or Power Steering Pulley Replacement for LS1 V8.
4. Install the serpentine belt.
5. Raise and suitably support vehicle. Refer to Vehicle Lifting.
