3.8. Service of system of cooling (oporozhneniye, washing and filling)
|
|
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 and 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 ways utilization of the fulfilled cooling liquid consult with local authorities. In many regions of the world special points on different reception of working off are equipped. At all do not merge old cooling liquid in the sewerage and on the earth! |
|
|
Recently nontoxical grades of antifreeze were developed, however they also demand care in the address. |
Check of a condition of components
|
|
- The wide range of engine failures is connected with violation of functioning of system of cooling. On the models equipped with AT, this system provides also ATF cooling, supporting thereby optimum conditions for transmission work.
- Check of a condition of components of system of cooling should be made after complete cooling of the power unit (not less than in three hours after an engine stop).
- Uncover a broad tank. The cooling liquid which was in system should be rather transparent. If liquid is painted in color of a rust, the system should be washed out and filled with a fresh mix (see below). If level of liquid does not reach top, add in a broad tank a little more mix of demanded structure (see. Check of levels of liquids).
- Attentively examine the top and bottom radiatorny hoses together with hoses of system of heating of the salon, having smaller diameter and located between the power unit and a partition of an impellent compartment. Check hoses on all their length and in case of identification of cracks, swellings and signs of aging of a material make replacement of defective components. Small cracks are usually simpler for making out at a hose szhimaniye.
|
- Check hoses on existence of the wiped sites.
|
|
- The softening of rubber testifies to the beginning of its destruction as a result of aging.
|
|
- Too hard tightening of a collar for the purpose of more reliable fixing on an union / branch pipe of the hardened hose does not promote the leak termination, and only leads to destruction of a material of a hose.
|
|
- Check all hoses on existence of swellings and traces of infiltration of oil at end faces. Cracks and small breaks in rubber come to light at a hose szhimaniye easier.
|
|
|
|
Originators of the real Management recommend to make replacement of hoses approximately time in two years regardless of their condition. |
|
- Check reliability of fastening of all hoses on the unions / branch pipes. Leakages of cooling liquid usually are shown in a look потеков rusty or white color on surfaces surrounding their source. If hoses are fixed on unions / branch pipes by collars of braided type, it will be reasonable to replace the last more reliable worm or screw.
- Having blown the compressed air, or by means of a soft brush, remove from gaps between plates of the heat exchanger of a radiator old leaves, remains of insects and other garbage. Try not to damage soft plates of the heat exchanger and not to cut about their keen edges fingers.
- Regularly, according to the schedule of routine maintenance of the car (see. The schedule of routine maintenance), the system of cooling should be emptied, washed out and filled with a fresh mix of antifreeze with water. Such service allows to prevent corrosion development in an okhladitelny path and considerably increases efficiency of functioning of system.
- Do not forget about precautionary measures which should be observed at service of system of cooling (see the prevention above).

Oporozhneniye
|
|
- Cock the parking brake and prop up wheels protivootkatny boots. In case of need remove protection of a case. It is necessary to start direct performance of procedures of service after complete cooling of the engine, i.e. not less than several hours later after trip end.
- Having waited final cooling of the engine, include ignition, include a heater сальна on the maximum productivity, then again turn a key in the situation OFF.
|
- Uncover a jellied mouth of a radiator.
|
|
|
|
If the engine yet completely cooled down, wrap up a cover rags for the purpose of elimination of risk of an oshparivaniye! |
|
-
For production of cooling liquid from a radiator remove a stopper of the drain gate in the right lower part of radiatorny assembly. If the stopper "became attached", or is not provided not, disconnect from a radiator the bottom hose and merge liquid through it.
|
|
- Remove drain jams of the block of the engine.
|
A.
B.
|
-
For the purpose of ensuring freedom of an effluence of liquid weaken a stopper of release of air jams.
|
|
|
|
Cooling liquid should be lowered in drain capacity of the corresponding volume which it is necessary to prepare in advance. Try not to allow antifreeze hits in eyes and on open sites of skin. |
|
- In case of need, while liquid merges from the block, disconnect a hose from a broad tank and remove the last. Wash out a tank pure water (in case of need with soap). Clear urovnevy labels on tank walls.
- Check a condition of radiatorny hoses and hoses of system of heating, and also collars of their fastening on unions and branch pipes (see above), replace the failed components.
|
|
Washing
|
|
- For washing of system of cooling submit to a radiator pure water from a garden hose.
- As soon as water will start to follow from drain gates pure, free from corrosion products, stop washing and strongly tighten jams of drain gates.
- In cases of especially strong pollution or violation of passableness of a radiator remove the last and make its obratnopotochny washing, having filled a garden hose in the bottom branch pipe — if to achieve positive result it is not possible, deliver a radiator in a car-care center workshop for carrying out necessary regenerative repair.
- Products of corrosion and dense deposits are removed from a path of system of cooling by chemical processing — follow instructions of manufacturers of the cleaner acquired by you.
|
|
|
|
At regular performance of procedures of washing of system and replacement of cooling liquid need for carrying out chemical processing of a path should not arise. |
Filling
|
|
- Check serviceability of a condition and reliability of fastening of all hoses of an okhladitelny path. Replace defective components, tighten collars.
- Start to fill in slowly a fresh mix of antifreeze with water in a radiator mouth. Continue filling until liquid level in a tank will not rise to a mark the MOVE on the translucent case of the last.
- Establish into place a cover of a radiator and tighten a stopper of release of air jams on the top hose of a heating path.
- Start the engine and let's to it get warm to normal working temperature, then, drive it on single turns about 2-3 minutes — on a measuring instrument on instrument a guard track, that the engine did not overheat. Muffle and wait complete cooling.
- Examine components of system of cooling on existence of signs of development of leaks, then check level of cooling liquid in a broad tank, in case of need make the corresponding adjustment.
- Transfer handles of a choice of temperature of submitted air and a choice of a high-speed mode of the fan to the maximum productivity.
- Start the engine, warm up it to normal working temperature.
- In summary make one more control check of level of liquid (see. Check of levels of liquids).
