Service of system of cooling

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 and 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 ways recyclings of the fulfilled cooling liquid consult with local authorities. In many regions of the world special points on any reception of working off are equipped. At all do not merge an old cooling liquid in the water drain and on the earth!

Recently nontoxical grades of antifreeze have been developed, however they also demand care in circulation.

Regularly, according to the schedule of routine maintenance of the car (see Has undressed the routine maintenance Schedule), the cooling system should be emptied, washed out and filled with a fresh mix of antifreeze with water. Such service allows to prevent corrosion development inside охладительного a path and appreciably raises 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 (the Section Check of a condition of components of system of cooling see) without fail should be checked. Defective components are subject to replacement. Do not forget about safety measures which should be observed at service of system of cooling (see the prevention in the Section beginning). Remember that the fulfilled cooling liquid is subject to recycling and should not merge in the water drain at all.

Опорожнение

PERFORMANCE ORDER

1. Cock a lay brake and prop up wheels противооткатными boots. It is necessary to start direct performance of procedures of service only after full cooling of the engine, i.e., after some hours 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 piece of a hose in diameter about 9.5 mm which second end lower in the prepared capacity. Open the gate, – in case of need take advantage of flat-nose pliers.
3. Having waited definitive cooling of the engine, uncover a jellied mouth and wait full опорожнения a radiator. Move drain capacity under the drain gate of the block and let out cooling liquid from the engine.

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

4. Check up a condition of hoses охладительного a path and collars of their fastening (the Section Check of a condition of components of system of cooling see).

Washing

PERFORMANCE ORDER

1. Completely having 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 infringement of passableness of a radiator, remove last (see the Head of System of cooling of the engine, salon and air conditioning heating) and deliver it for regenerative repair and service in a car-care centre workshop. Products of corrosion and dense adjournment leave from a path of system of cooling by chemical processing, – follow instructions of manufacturers of the cleaner got by you.

At regular performance of procedures of washing of system and replacement of a cooling liquid necessity for carrying out of chemical processing of a path should not to arise.

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

Refuelling

PERFORMANCE ORDER

1. Tighten drain gates.
2. Translate the handle of management of system of heating of salon on the maximum heating.
3. Slowly fill in in a radiator fresh, made in a proportion 1:1 a mix of antifreeze with water. Continue pouring until liquid level 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 for five minutes and once again check up level of a cooling liquid in a radiator, in case of need make updating.
4. Without establishing a cover on a radiator, start the engine and warm up it before opening of the valve of the thermostat (the 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 allow to it to cool down. Add in a radiator of a little more liquid, having finished its level to the bottom cut of a jellied mouth.
6. A way сжимания the top hose of a radiator let out from it air, in case of need add a little more a cooling liquid. Establish into place a radiator cover.
7. Translate the handle of management of system of heating of salon on the maximum heating, include for the maximum speed the heater fan.
8. Start the engine, warm up it to normal working temperature and check up system on presence of signs of leaks.
9. Unit overheating testifies to presence in охладительном a path of air stoppers. Muffle the engine and allow to it to cool down, – air should leave a path automatically. Repeating procedure, achieve a demanded temperature mode of the working engine.
