2008 Cadillac SRX Power Steering Reservoir

You should fill the pump reservoir with fluid to the minimum system level, full cold level, or middle of hash mark on the cap stick fluid level indicator, fully charge the hydro-boost accumulator if equipped with hydro-boost, and raise the vehicle, with the key on engine off, turn the steering wheel from stop to stop 12 times, verify power steering fluid level per operating specification, start the engine, rotate steering wheel from left to right, check for sign of cavitation or fluid aeration (pump noise/whining) and verify the fluid level.

You should remove the front air deflector, place drain pans under the vehicle as needed, remove the air cleaner inlet duct, remove as much power steering fluid from the remote power steering fluid reservoir as possible, disconnect the power steering cooler outer hose from the remote power steering fluid reservoir and the power steering fluid reservoir outlet hose from the remote power steering fluid reservoir and remove the remote power steering fluid reservoir bolts and the remote power steering fluid reservoir from the vehicle.
