2009 Chevrolet Trailblazer Power Steering Pump Seal

First, you need to remove the front air dam deflector and install a drain pan under the vehicle. Then, please disconnect the power steering hose assembly from the Power Steering Cooler. Finally, you should remove the power steering cooler mounting bolts and remove the power steering cooler from the radiator support.

First, you need to fill the pump reservoir with fluid to the minimum system level, FULL COLD level, or middle of the hash mark on the cap stick fluid level indicator. If it is equipped with hydro-boost, you should fully charge the hydro-boost accumulator by starting the engine, firmly applying the brake pedal 10-15 times, and turning the engine OFF. Then, please raise the vehicle until the front wheels are off the ground, key on engine OFF, and turn the steering wheel from stop to stop 12 times. Finally, you should verify the power steering fluid level per operating specification, start the engine, rotate the steering wheel from left to right, and verify the fluid level.
