Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the bracket(s) to the pump.

Tighten

•	Tighten the rear bracket-to-pump stud nuts to 50 N·m (37 lb ft).

•	Tighten the front bracket to front pump bolts to 50 N·m (37 lb ft).




2. Loosely install the pump assembly.

Important: 

•	Do not start the engine with any power steering hoses disconnected. After connecting the power steering hoses, ensure that there is clearance between the hoses and the drive belt, the sheet metal, or any other components where hose chafing or interference may result.

•	Improperly installed hoses are subject to chafing and other abuses.
