Check of functioning of the cooling system and frost resistance of cooling liquid Address also materials of the Section Check of a State and Replacement of Hoses of a Motive Compartment, localization of leaks.
Noticeable leak of cooling liquid and/or availability of oil in liquid, and also white cloudlets in the fulfilled gases indicate existence of defect in sealing laying of a head of cylinders. Check of frost resistance of cooling liquid
Before a winter season it is necessary to check surely concentration of antifreeze in cooling liquid, especially if in system clear water was in use filled in. You will need the special areometer with graduation of frost resistance of antifreeze. Check Removal of liquid
Antifreeze addition Address materials of Specifications. In need of protection of the engine up to the temperature of -25 °C concentration of antifreeze in cooling liquid has to make 40%. In need of protection up to the temperature of -35 °C concentration of antifreeze has to make 50%.
If concentration increases to higher level, degree of protection of the engine begins to go down and, besides, heat-removing properties of cooling liquid worsen. Air traffic jams If after liquid replacement the engine overheats, the reason, most likely, available air traffic jams in system. These traffic jams do not allow liquid to circulate on all system. They appear as a result of too hasty gas station of system. If you consider that in system there are air traffic jams, first of all try to squeeze all visible hoses in turn. You at once define, the hose is filled with liquid or air. As a rule, all air traffic jams disappear after the first (after liquid replacement) start of the engine. At the working heated-up engine include a heater and its fan. Warm air has to come to salon in enough. If temperature of the given air low, the reason, perhaps, is an air stopper. Consequences of emergence of air traffic jams in system can be very serious (not simply decrease in overall performance of a heater). The big stopper can stop circulation of liquid in the engine. To make sure of lack of traffic jams in the engine, touch the top hose of a radiator at the working engine — it has to be hot. If the hose cold, it demonstrates existence of an air stopper in the engine or about the faulty thermostat. If you could not get rid of air traffic jams, allow the engine to cool down completely, uncover a broad tank, try to squeeze system hoses. If it did not help, merge all cooling liquid in a pure container and again fill system with the same liquid, following the recommendations provided above. |
