You make removal in the following order:
– switch off ignition and disconnect a wire of "weight" from the rechargeable battery;
– disconnect a wide hose from a cover of a head of the block of cylinders;
– having pulled up and at the same time turning, remove tips with high-voltage wires from spark plugs;
– a stream of compressed air clear candles that will exclude hit of dirt in the engine cylinder after a reversing of spark plugs. Turn out spark plugs;

Fig. 3.2. An arrangement of round nuts of fastening of a cover of a head of the block of cylinders to tubes for spark plugs
– turn out the round nuts fixing a cover of a head of the block of cylinders to tubes for spark plugs
– uncover a head of the block of cylinders. If she sits densely, bring down her a kiyanka or insert mount between a head of the block of cylinders and a cover and raise it.
When using mount do not damage privalochny surfaces of a head of the block of cylinders and a cover, otherwise in the place of damage engine oil will proceed.
You make installation in the following order:
– clear privalochny surfaces of a head of the block of cylinders and a cover. Remove with a plastic scraper the remains of old laying and sealant, then clear surfaces solvent. If on surfaces there are traces of laying or engine oil, then after installation of a cover in these parts there can be oil leak;
Fig. 3.3. Places of putting RTV sealant on a head of the block of cylinders
– apply on eight places shown in
the figure 3.3
, a RTV sealant layer. Establish consolidations for tubes of spark plugs in a cover so that indexes on consolidations were directed towards a gear belt;
– establish new laying of a cover on a head, then establish a cover of a head of the block of cylinders and fix it by round nuts, having tightened them for several equal passes.
Further installation of a cover is carried out to the sequences, the return to removal.
