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

Attentively study radiator and heater hoses. Examine hoses on all length, at revealing of cracks, swellings and signs of ageing of a material make replacement. Cracks are easier for finding out a way сжимания a hose. Special attention turn on installation sites of the fixing collars, capable to cut or pierce hoses.
|
Make sure of reliability of fastening of all шланговых connections. Leaks of a cooling liquid usually are shown in the form of white or brown-red adjournment around a place of infringement of hermetic sealing. If for fastening any of hoses collars of wire type are used, it makes sense to replace their worm/screw.
Compressed air blow a forward part of the heat exchanger of a radiator, and at a corresponding complete set, also condenser K/V. Remove their backlashes between plates of heat exchangers remains of insects, foliage and other extraneous subjects, - try not to damage a plate and not to cut about them fingers.
If necessity for updating of level of a 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 a cooling liquid
|
|
Do not suppose antifreeze hit on open sites of a body and the painted surfaces of the car. Casual splashes immediately wash off a plentiful quantity of water. Remember that antifreeze is extremely a 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 stored in leaky closed container, immediately collect cooling liquid spilt on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About rules recyclings of the fulfilled cooling liquid consult on HUNDRED, - in many countries special points on any reception of working off are equipped, - at all do not merge an old cooling liquid in the water drain or on the earth! |
|
|
Recently nontoxical grades of antifreeze are developed, nevertheless, they also should to be utilised in the organised order. |
|
|
Before the beginning of a winter season it is necessary to check up necessarily concentration of antifreeze in a cooling liquid, especially if in system in the course of summer operation of the car in system water was added, - take advantage of appropriate amount prograduated ареометром.
Slightly warm up the engine so that the top hose of a radiator has heated up, - at measurement of concentration of antifreeze the liquid temperature should make an order +20С.
Cautiously turn away a stopper of a broad tank.
|
|
At the hot engine the stopper of a broad tank should be opened extremely cautiously, preliminary having covered with its rags. To open a tank follows only at temperature of a cooling liquid not above + 90С! |
Pump out liquid test in the working chamber ареометра.
In moderate widths concentration of antifreeze should providing protection of system to temperature-25S, in strong frosts to-35S.
|
|
Replacement of a cooling liquid of the engine
Replacement of a cooling liquid should be made strictly according to the Schedule of routine maintenance of the car (see Has undressed the routine maintenance Schedule). The order of performance of procedure is resulted above in Section Check of level of working liquids.
