3.2.18. Cleaning of the block of cylinders

GENERAL INFORMATION

Prevention

Caps of channels of system of cooling are densely pressed in the block of cylinders.


PERFORMANCE ORDER
1. Remove caps of channels of cooling of the block for what in blow on a small beard drive inside one of the parties of a cap and get a cap flat-nose pliers.
2. Carefully clear the block of the consolidation remains.
3. Remove covers with loose leaves, designate them and store separately.
4. Turn out carving caps of the block of cylinders (or drill, and then banish a carving).
5. At strong pollution of the block clean all channels a vapor jet and the compressed air (it is recommended to carry out in car-care center), wash out the block outside detergent. Banish all carving openings, clean and blow the compressed air. Dry the block and grease with veretenny oil to protect from corrosion.

6. Banish all carvings of the block of cylinders, having cleared thereby of dirt. Dry carving openings to exclude breakage of the block of cylinders at the expense of a hydraulic pressure at a bolt wraparound.
7. If the block is not so strongly polluted, it is possible to be limited to washing by soap solution. Irrespective of a way of cleaning very carefully wash out all internal lubricant channels and well dry. Walls of cylinders oil to prevent emergence of a rust.
8. Establish covers of radical bearings, bolts tighten by hand.

9. Press new caps without distortions, previously having greased them with hermetic. Wrap on non-drying hermetic new caps of oil channels. Densely tighten caps.
