You should disconnect power steering hoses from the pump before removing the Power Steering Pump mounting bolts to extract the pump from the engine. The Power Steering Pump should be positioned on the engine before installing its mounting bolts which require 26 nm of torque (19 ft. Lbs.).

Detach power steering fluid lines from the pump before removing the two supporting bolts from the Power Steering Pump. Secure the new Power Steering Pump in position onto the engine by using the two mounting bolts and torque them to 26 n.m (19 lb ft). The power steering hoses need to be reconnected to the pump followed by installation of the evaporative emission canister purge valve (if installed) and return of upper air cleaner along with duct. Add the recommended power steering fluid to the pump before conducting an air bleed procedure of the power steering system.
