Removal and installation of covers of heads of cylinders


  1. Disconnect a negative wire from the battery.
  2. Remove assembly of the air cleaner (The head of the Power supply system and production of the fulfilled gases).
  3. Remove hoses of ventilation of a case and management of functioning of system of catching of vapors of fuel.
  4. Remove an arm of a cooling tube from a cover of the left head of cylinders.
  5. Disconnect candle wires from spark plugs (it is necessary to pull only for a wire tip cover). It makes sense to mark previously wires for a guarantee of their correct connection at assembly.
  6. Remove from hairpins of covers of heads of cylinders plastic holders of wires and put them together with wires aside.

Holders try to pull vertically up - they are rather fragile and can be easily broken in case of formation of the slightest distortion at removal.

  1. Give bolts of covers of heads of cylinders.

Part of fixture is not bolts, but hairpins - apply on surfaces of covers of a tag around installation of hairpins that at assembly to have an opportunity to arrange fixture in a former order.

  1. Uncover heads of cylinders.
  1. After a cover obstukivaniye the hammer with rubber brisk, lift it up.

If the cover "stuck", tap it slightly for release on perimeter the hammer with soft brisk. If the obstukivaniye did not help, try to push in a joint between a cover and a head an edge of a spackling knife and with its help to cut a layer of old sealant. Do not try to hook a cover the lever filled in a joint - it is fraught with damage of the interfaced surfaces.


The interfaced surfaces of both heads and their covers before installation of the last have to be smoothed carefully out. By means of a pro-masonry scraper remove all traces of material of old laying and sealant from the interfaced surfaces, then wipe surfaces with the rags moistened in acetone. If at installation to leave marks of sealant or oil on the interfaced surfaces it will lead to development of leak of oil in the near future.

Metallized (on a metal substrate) silicone laying if they are not damaged are subject to reuse.


  1. Make sure that carving openings in heads are absolutely pure. For removal of traces of sealant and restoration of the damaged rounds banish a carving of openings a tap.
  2. Before installation of covers apply laying and to heads of cylinders.
  3. Carefully establish a cover on the first head and screw fixing bolts / hairpins.
  4. Tighten fixture with the required effort in three stages.

The VKOY CASE do not tighten bolts/hairpin of covers of heads of cylinders stronger, than it is required.

  1. Further installation in an order, the return to a removal order.
  2. Start the engine and carefully check it for leaks in the course of a warming up.
