Service of system of cooling

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.

Regularly, according to the schedule of routine maintenance of the car (see. Undressed 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.

During service also the condition of all hoses of system and a cover of a jellied mouth of a radiator (without fail should be checked see. Section Check of a condition of components of system of cooling). Defective components are subject to replacement. Do not forget about precautionary measures which should be observed at service of system of cooling (see the prevention at the beginning of the Section). Remember that the fulfilled cooling liquid is subject to utilization and should not merge in the sewerage at all.

Oporozhneniye

PERFORMANCE ORDER

1. Cock the parking brake and prop up wheels protivootkatny boots. It is necessary to start direct performance of procedures of service after complete cooling of the engine, i.e., some hours later after trip end.
2. Get drain capacity under radiator plums, – the drain gate is located on a wall of the bottom tank. Pull on the gate a hose piece in diameter about 9.5 mm which second end lower in the prepared capacity. Open the gate, – in case of need use flat-nose pliers.
3. Having waited final cooling of the engine, uncover a jellied mouth and wait a full oporozhneniye of a radiator. Move drain capacity under the drain gate of the block and let out cooling liquid from the engine.

If after gate opening liquid does not start to merge, clean an opening a small screw-driver.

4. Check a condition of hoses of an okhladitelny path and collars of their fastening (see. Section Check of a condition of components of system of cooling).

Washing

PERFORMANCE ORDER

1. Having completely emptied system, wash out a radiator the pure water submitted from a garden hose, continue washing until the pure transparent stream will not start to follow from the top hose.
2. In cases of especially strong pollution or violation of passableness of a radiator, remove the last (see. The head of System of cooling of the engine, salon and air conditioning heating) also deliver it for regenerative repair and service in a car-care center workshop. 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.

3. Disconnect perelivny a hose from a broad tank and wash out the last pure water. Again connect a hose.
4. Periodically delete outside of a radiator the stuck extraneous subjects.

Filling

PERFORMANCE ORDER

1. Tighten drain gates.
2. Transfer the handle of management of system of heating of salon to the maximum heating.
3. Slowly fill in in a radiator the fresh, 1:1 mix of antifreeze made in a proportion with water. Continue filling until level of liquid will not rise to the bottom cut of a jellied mouth. Add cooling liquid in a broad tank, having finished its level to the bottom mark in a tank wall. Wait five minutes and once again check level of cooling liquid in a radiator, in case of need make adjustment.
4. Without establishing a cover on a radiator, start the engine and warm up it before opening of the valve of the thermostat (liquid should start to circulate through a radiator, thus there will be a warming up of the top hose of the last).
5. Muffle the engine and let's to it cool down. Add in a radiator a little more liquid, having finished its level to the bottom cut of a jellied mouth.
6. By a szhimaniye of the top hose of a radiator let out from it air, in case of need add a little more cooling liquid. Establish into place a radiator cover.
7. Transfer the handle of management of system of heating of salon to the maximum heating, turn on for the maximum speed the heater fan.
8. Start the engine, warm up it to normal working temperature and check system on existence of signs of leaks.
9. Overheating of the unit testifies to existence in an okhladitelny path of air jams. Muffle the engine and let's to it cool down, – air should leave a path automatically. Repeating procedure, achieve a demanded temperature mode of the working engine.
