The Escalade is a full-size luxury SUV built by General Motors and sold under the Cadillac brand. The Cadillac Escalade was introduced in 1999. The Escalade shares a power steering pump with its platform cousin, the Chevrolet Tahoe, so installation procedures are the same between the two vehicles.

Step 1

Remove the upper radiator fan casing, drive belt and power steering pulley to gain access to the power steering pump.

Step 2

Place a drain pan underneath the pump to catch leaking fluid. Clamp off the filler hose connected to it.

Step 3

Remove the hoses and lines connected to the power steering pump. Remove the two bolts from the front and the two bolts from the rear. Remove the pump from the Escalade's engine bay and place in the drain pan to fully discharge.

Step 4

Bolt the Escalade's power steering pump to its mount, using the torque wrench. Tighten the bolts to 37 foot-pounds.

Step 5

Reattach the hoses and lines to the pump; then install the pulley. Replace the upper radiator fan casing and the drive belt.

Step 6

Replenish the Escalade's power steering reservoir to the halfway mark with the engine cold to begin bleeding the system.

Step 7

Turn the ignition to the "On" position without cranking the engine. Turn the steering wheel from lock-to-lock 15 times. Check the power steering fluid level to ensure it is within operating capacity.

Step 8

Start the engine and rotate the Escalade's steering wheel. Listen closely for whining or whirling noises; check the system for leaks.
