    Q:
    How to replace the power steering pump on a LY7 engine on Cadillac STS? Posted by Customer
    A:
    The replacement of the Power Steering Pump (LY7 - Gas, 6 CYL, 3.6L, SFI, V6, Alum) requires the front air deflector and power steering pulley removal followed by placement of a drain pan underneath the vehicle. The air cleaner intake duct removal follows power steering reservoir outlet hose and pressure hose separation from the pump. Finally, you must separate three power steering bracket mounting bolts to extract the Power Steering Pump with its bracket. The Power Steering Pump bracket needs to be detached from its position on the pump. The Power Steering Pump needs attachment to its bracket before reinstalling the complete assembly into the vehicle. The Power Steering Pump bracket installation requires securing it to engine mounting bolts (1, 2 and 3) while tightening them sequentially to 50 n.m (37 lb ft). Replace the power steering pressure hose and reservoir outlet hose after which you must remove the drain pan. After power steering pulley installation a technician must install the air cleaner intake duct before performing power steering system bleeding operations. The last step includes front air deflector replacement.

    Q:
    How to replace the Power Steering Pump (LH2) on Cadillac STS? Posted by Customer
    A:
    Front air deflector removal must start along with the power steering pulley before installing a drain pan under the vehicle. The first step consists of removing the air cleaner assembly followed by disconnecting the power steering reservoir outlet hose and pressure hose from the Power Steering Pump. You must also take out the Power Steering Pump to engine mounting bolt together with the power steering bracket to engine bolts. Extract the power steering unit with its bracket out of the vehicle until you obtain separate components of the steering pump and bracket. Installation starts with connecting the power steering bracket to the Power Steering Pump before returning the assembly into position where the power steering bracket connects to the engine with 50 nm torque (37 ft. Lbs.) per the fastener notice in service precautions. The installation proceeds by securing the Power Steering Pump to its engine mounting bolt before tightening to 50 nm (37 ft. Lbs.) while restoring the power steering pressure hose and power steering reservoir outlet hose to the pump. Complete the process by installing the power steering pulley before the air cleaner assembly and conduct a power steering system bleed followed by front air deflector reinstallation.
