Check of functioning of system of cooling and frost resistance of cooling liquid, liquid replacement
General information
Many serious violations in operation of the engine are connected with malfunctions of system of cooling. If the car is equipped with automatic transmission, its functioning and service life also are directly connected with work of system of cooling.
|
|
Check of system of cooling should be made at the cold engine therefore it is better to be engaged in it before the trip first in the present day, or not earlier than in three hours after останова the engine.
Slowly, being careful in case the engine yet absolutely cooled down, uncover a broad tank. Carefully wash out it from within and outside pure water. Also wash out a jellied mouth of a tank. Existence of traces of corrosion in a jellied mouth means that it is necessary to replace cooling liquid. Cooling liquid in a broad tank should be rather pure and transparent. If liquid has a brownish shade, empty system and fill in in it new cooling liquid (see. Section Check of level of working liquids).

Attentively study radiator and heater hoses. Examine hoses on all length, at identification of cracks, swellings and signs of aging of a material make replacement. Cracks are easier for finding by a hose szhimaniye. Special attention turn on installation sites of the fixing collars, capable to cut through or pierce hoses.

Make sure of reliability of fastening of all shlangovy connections. Leakages of cooling liquid usually are shown in the form of white or brown-red deposits around a place of violation of sealing. If for fastening any of hoses collars of wire type are used, it is meaningful to replace them worm/screw.
The compressed air blow a forward part of the heat exchanger of a radiator, and at the corresponding complete set, also the К/В condenser. Remove them gaps between plates of heat exchangers remains of insects, foliage and other extraneous subjects, - try not to damage plates and not to cut about them fingers.
If need for correction of level of cooling liquid arises regularly thus that traces of any external leaks are absent, it is necessary to make check of system of cooling by pressure in conditions HUNDRED.

Check of frost resistance of cooling liquid
|
|
Do not allow antifreeze hit on open sites of a body and the painted surfaces of the car. Casual splashes immediately wash away a plentiful quantity of water. Remember that antifreeze is extremely toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences, up to a lethal outcome. Never leave antifreeze being stored in leaky closed container, immediately collect cooling liquid spilled on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About rules utilization of the fulfilled cooling liquid consult on HUNDRED, - in many countries special points on different reception of working off are equipped, - at all do not merge old cooling liquid in the sewerage or on the earth! |
|
|
Recently nontoxical grades of antifreeze are developed, nevertheless, they also should to be utilized in the organized order. |
|
|
Before the beginning of a winter season it is necessary to check surely concentration of antifreeze in cooling liquid, especially if in system in the course of summer operation of the car in system water was added, - use as appropriate pro-graduated areometer.
Slightly warm up the engine so that the top hose of a radiator heated up, - at measurement of concentration of antifreeze the temperature of liquid should make about +20°С.
Carefully unscrew a stopper of a broad tank.
|
|
At the hot engine the stopper of a broad tank should be opened extremely carefully, previously having covered it with rags. To open a tank follows only at temperature of cooling liquid not above + 90°С! |
Pump out liquid test in the working chamber of the areometer.
In midlatitudes concentration of antifreeze should providing protection of system to temperature - 25°С, in hard frosts to - 35°С.

Replacement of cooling liquid of the engine
Replacement of cooling liquid should be made strictly according to the Schedule of routine maintenance of the car (see. Undressed the Schedule of routine maintenance). The order of performance of procedure is given above in the Section Check of level of working liquids.
