Installation
1. Install in the reverse order, tightening all nuts and bolts to the torque specified in the Specifications. When securing the subframe to the underbody, screw 100 mm long rods into the nuts to adjust the position of the bolt holes. With the front of the subframe aligned, insert the rear bolts, then remove the rods and insert the front bolts. When connecting the steering column to the steering gear, refer to Chapter Suspension and steering. Bring the fluid level in the power steering hydraulic system to the normal level. Fill the engine with oil and the cooling system with coolant as described in Chapter Maintenance. Bleed the fuel system as described in Chapter Power and exhaust systems. On turbocharged models, before starting the engine, make sure the lubrication system is filled as described in Chapter Maintenance. Before performing a test drive, press the brake pedal several times to bring the brake pads to their normal position.
