1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!


2. Uncover with heads cylinders of the ignition distributor with the wires connected to it by VV. Disconnect wires from the plugs on a head of cylinders and its cover (see the Head Routine maintenance). Do not forget to mark wires in order to avoid violation of an order of ignition at assembly.
3. Mark and disconnect all procedures of a wire impeding the implementation and hoses from the case of a throttle and a cover of a head of cylinders.
4. Carefully wipe a cover in order to avoid hit of garbage in a head cylinders/assembly of the valvate mechanism.
5. Turn out bolts of fastening of a cover of a head of cylinders – act as it should be, the return specified in a picture (see an illustration below).
6. Accurately uncover together with sealing laying. If laying of a podlipl to the interfaced head surface, tap a cover the hammer with soft brisk for the purpose of destruction of a layer of sealant. Do not make at all attempts to separate a cover by a poddevaniye its lever entered between the interfaced surfaces.

Installation

 PERFORMANCE ORDER

1. Separate old laying, then carefully smooth out the interfaced surfaces of a head of cylinders and its cover. Having scratched out traces of old sealant and fragments of laying, wipe surfaces with the rags moistened in acetone.
2. Impose a little RTV sealant on corners where the interfaced surface of a head adjoins to assembly of yokes (see an accompanying illustration). Wait about five minutes, waiting for the moment of the beginning of polymerization of sealant.

Make sure that the top layer of sealant slightly hardened, only after it start installation of a cover (in the conditions of the increased humidity polymerization of sealant can begin with a small delay).


3. Fill cast laying in the flute going on cover perimeter. Put the isolating plugs through passage in a cover, having slightly greased them with solution of soap water. Lay a cover on a head, then screw fixing bolts and tighten them in that order (see an accompanying illustration) with the required effort (see Specifications).
