THE GENERAL DATA

If at you the new car of foreign manufacture, moreover with инжекторным the engine, it is possible not to read further. But if the car second-hand, with the carburettor motor – then business another. Actually, power supply systems and ignitions among themselves are not connected. But on modern engines with injection you will not meet приснопамятного the mechanical distributor, breaker contacts. And on carburettor – as much as necessary. And not to potter then on a frost, contacts should be cleaned, a distributor cover – too (and it is better to replace). Even better – to replace classical system of ignition on electronic (if still there were automobile owners who have not made it).

Do not forget about high-voltage wires. After driving couple of years on our "salty" roads they are desirable for changing, and it is better – on wires with a silicone cover which are less sensitive to differences of temperatures. Besides, on them hoarfrost which often is at the bottom of absence of a spark is not formed. By the way, corrosion or a bad inhaling of storage plugs can be the banal reason of malfunctions of ignition.

Separately – about candles. Usually them change through 15-20 thousand kilometres, i.e. Time in one and a half year (we do not take supermodern, maintaining 100 thousand in km and more). It is not necessary to save on candles – to calcinate, clean and regulate backlashes. Change at least once a year it it is inexpensive. Also put new on the threshold of winter. Fuel system

Quite often it is at the bottom of unsatisfactory work of the engine during winter time. And all – because of the water condensate which has accumulated in a fuel tank. If in a tank there is a drain stopper, water can be merged simply if is not present – to "neutralise", having applied so-called "вытеснители a moisture". Almost all leading manufacturers of auto chemical goods who are present in the Russian market (STP, Loctite, WynnХs, Aspokem), offer similar preparations which are filled in in a fuel tank and gradually clear the power supply system.

To the superfluous will not put the new filter of thin clearing of fuel, to clean the carburettor and if the motor has injection system – to be convinced of cleanliness of injectors.

To owners of diesel foreign cars, especially if the car was maintained earlier in the country with a soft climate, it is necessary to take care of equipment of fuel system by special devices of heating. Practice shows what to get the diesel motor at–20 With happens difficultly as fuel loses fluidity (how much "winter" solar oil which at us is on sale in the winter is – it is possible to guess only). One of effective measures – application warmed up топливоприводов and filters. Thus to start up the diesel motor it is possible even at–40 for S.Podogrev it is carried out by elements which eat from the regular accumulator.

The current consumed by them makes nearby 5А, inclusion of heaters for 5–10 minutes practically does not affect accumulator capacity.
