11.24.3. An engine sink
For environmental contamination prevention wash the engine and a motor compartment in specially taken away places equipped with the waste water drain or local treatment facilities.
While in service the car on external surfaces and engine elements dirt and oil adjournment collect. In the field of oil картера the engine they worsen oil cooling owing to what its viscosity decreases, engine details intensively wear out. Accumulated near oil щупа the engine abrasive particles at each check of level of oil can get in картер the engine. The dirt and oil on elements of a control system of the engine, and on high-voltage wires of system of ignition in a motor compartment create electric equipments (especially in crude weather) undesirable electric chains which complicate start-up of the engine and lead to faults in its work. And at last, with strongly polluted engine not to pass checkup.
Wash a block head, the block of cylinders and oil картер the engine with special washing-up liquids which delete all kinds of pollution. The washing-up liquids got in shop, it is possible to divide on two groups:
– Shampoos for an engine sink;
– Universal remedies, for example, for a sink of the engine and removal of bitumen stains from a paint and varnish covering of a body.
From make-shifts it is possible to use the detergent powder dissolved in water or a liquid for ware washing.
It is forbidden to use gasoline as any spark (even the category of a static electricity between your clothes and a car body) can cause ignition in a motor compartment for a sink of the engine.
It is forbidden to use open fire. Do not smoke and do not get the engine before full removal of the rests of a washing-up liquid from its surface.
If there is no possibility to dry the engine after a sink the compressed air, try to avoid water hit on electric equipment devices, high-voltage wires, ignition coils.
It is forbidden to start up the engine before full removal from its surface of washing structure or water — in this case the risk of failure of an electric equipment sharply increases.
To spend a sink of the engine it is more preferable on special automobile sinks. It is standard service of the majority of automobile sinks: the engine at first process special structure, then wash manually then it rinse with water under pressure and dry compressed air. After a sink it is necessary to check up serviceability of devices of an electric equipment and engine work.
In the course of an engine sink it is impossible to suppose water hits on the generator, a starter and elements of a control system of the engine.
At carrying out of a sink of the engine in "house" conditions the small scraper, a painting brush, a tooth-brush (for hard-to-reach spots), capacity with water or a garden sprayer be required to you. Considerable adjournment of a dirt and oil need to be removed at first a scraper. If the scraper near at hand is not present, for removal of adjournment of a dirt and oil the screw-driver with the long handle well will approach, and it is better — a wooden shovel. After a sink blow in the engine the compressed air.
If you do not have compressor for обдува the engine the compressed air it is possible to use a vacuum cleaner, having connected a hose to its exhaust outlet.
