Salt that is sprayed on the roads in winter gets through the cracks under the hood and is deposited on the radiator, cables and other parts. This salt coating prevents moisture from evaporating and increases corrosion.
After washing, check if there is enough lubrication in the levers and rods, control cable. Lubricate them additionally if necessary.
Sequence of work
Washing is carried out on a cold engine, since on a warm engine the cleaning agent will evaporate before it has time to act on the dirt film.
1. Turn off the ignition.
2. Close the electronic unit, generator and fuel supply system with a rag or plastic bag, otherwise there will definitely be interference in the ignition or on-board electronics.
3. Start with the hood. Rinse with plenty of water, then clean with car shampoo using a sponge and rinse again with water. Don't forget about the engine stiffeners - that's where most of the dirt accumulates.
4. Wash the radiator with plenty of water using a narrow hose end. Treat areas with insect remains with a detergent that dissolves protein (dishwashing liquid).
Attention! Hard brushes can damage soft radiator fins.
5. Wash the grooves and profiled parts.

7. To remove water from the engine area after washing, use a compressed air gun.
Engine protection varnish
To reduce the accumulation of dirt on the engine and in the surrounding area, treat the engine and peripherals with a special heat-resistant protective varnish (). For the rest of the areas, it is sufficient to use a spray or a preservative. 3.10.
