Removal
Open the hood and place a clean rag under the corners to protect the car's paintwork when removing the hood.
Disconnect the hose from washer nozzles and electrical connectors. Tie a thin long cord to the hose and electrical connector. Pull the electrical wiring and hose out of the hood, untie the cord from them, leave it in the hood. Later, the cord will be needed to install the electrical wiring and hose in the hood.
Using a marker, mark the position of the hinges on the hood.
Have an assistant support the hood in the open position and use a screwdriver blade to detach the gas-filled strut from the hood. If it is necessary to remove the gas-filled hood strut from the car, remove the lower part of the support in the same way.
If a new pneumatic support is to be installed, the gas must be removed from the old support for disposal. To do this, secure the supports in a vice by the section X, shown in Fig. 16-10. To avoid accidents, be sure to clamp the support at the specified area. At a distance equal to 1/3 of the length, saw the body of the air support. When sawing the support, use glasses to protect your eyes
Fig. 16–10. Section of support X, for which it is necessary to clamp the support in a vice: X=50 mm
Unscrew the bolts securing the left and right hood hinges and carefully remove the hood.
Check the condition of the hood hinges for play and wear; replace them if necessary.
Installation
With two assistants, install the hood and screw in the hood hinge bolts by hand. Align the hood hinges according to the marks made earlier and tighten the hood mounting bolts.
Secure the gas-filled struts to the hood by pressing the stop firmly until it locks onto the hood's spherical hinge.
Tie the electrical connector and washer hose to the cord and pull them into the hood. Push the hose onto the washer nozzles windshield.
Adjusting the hood position
Close the hood and adjust the height of its rear section relative to the adjacent body elements. The height is adjusted using the elongated holes for the bolts 2 (see Fig. 16–9) for fastening the hinge to the hood. To adjust, loosen the bolts, change the relative position of the hood hinge relative to the hood, and tighten the bolts.
Close the hood and check its position relative to the adjacent surfaces. When the hood is closed, the gap along its perimeter should be the same on all sides and be 3.5 mm. To adjust, loosen bolts 3 securing the hood hinges to the body and, moving the hood, adjust its position. After adjustment, tighten the hood hinge bolts.
To adjust the front part of the hood in height, loosen nut 15 (see Fig. 16–9). securing pin 12 of the lock and rotate it to the corresponding side of the lock pin, then tighten the nut.
If the hood lock does not lock securely, loosen nut 15 securing pin 12 of the lock and, by moving the lock pin due to the enlarged hole in the hood, achieve its alignment with the hood lock socket. Tighten the nut securing the hood lock pin.
