To fix the Brake Booster on a 3.4l engine you need the power Brake Booster holder item j 22805-b. Start by taking off the negative
Battery Cable then removing the insulator on the left instrument panel. Unplug the stop lamp switch from its electrical connection while removing the clip attached to its Brake Booster hook. This disconnects the Brake Pedal(animation rod). Cut some cooling fluid before taking off the cross vehicle brace and air cleaner inlet duct. Begin fuel system decompression then uninstall all ducts related to the evap canister purge valve and fuel system feeds while setting them off to the side. Sever the bypass tubes of the coolant outlet and inlet lines before you take the heater inlet hose off. Move the engine forward and then take off the power brake level sensor's electrical connector. Do not remove the brake pipes at the master cylinder end; keep them in place and disconnect the master cylinder by its two retaining nuts. To work on the Brake Booster remove the vacuum check valve only when you keep the combined vacuum hose and check valve as one piece. Fit the power Brake Booster holder (J 22805-B) to the booster through master cylinder retaining nuts then release the cowl lock to rotate the booster counterclockwise using a ratchet and flat-bladed tool alongside depressor of the Brake Booster locking tab. Take out the vacuum Brake Booster and remove its attaching piece called the power Brake Booster holder part number j 22805-b. Install the booster by keeping its internal parts original and undamaged locking flanges. Place the vacuum Brake Booster on the cowl and turn it counterclockwise until the locking flanges engage. Afterward, use a ratchet on the power Brake Booster holder (J 22805-B) to rotate the booster clockwise which locks the tab. Install the vacuum hose with check valve when you take out the power Brake Booster holder (J 22805-B). Put the master cylinder back on top of the booster unit and fasten its retaining nuts with a torque of 33 nm (24 ft. Lbs.). Set the brake fluid sensor electrical connection while placing the engine back in its regular position and fastening the engine mount struts on both sides. Put back the heater inlet pipe and join the coolant outlet and inlet bypass tubes while attaching the evap canister purge valve, fuel feed and return pipes. Complete the work by putting back the air cleaner inlet, crossing brace, filling the cooling system, connecting the pushrod to the Brake Pedal, attaching the clip, joining the stop lamp electrical connector, installing the instrument panel insulator, and linking the battery negative cable.
