Installation
1. Install in reverse order, tighten all nuts and bolts to the torque given in the Specifications. On models with a 2.0L engine, when attaching the subframe to the bottom, screw 100mm rods into the nuts to adjust the position of the bolt holes. With the front of the subframe aligned, insert the rear bolts, then unscrew the rods and insert the front bolts. At connection of a steering column with the steering mechanism be guided by the Head Suspension and steering. Top up the fluid level in the power steering hydraulic system. Fill the engine with oil and the cooling system with coolant as described in Chapter Transmission. Before performing a test drive, depress the brake pedal several times until the brake pads return to their normal position.
