Service of system of cooling (опорожнение, washing and refuelling)

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 (Specifications see), 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 (Routine maintenance see the Head) 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).

Опорожнение

 PERFORMANCE ORDER

  1. Cock a lay brake and prop up wheels противооткатными boots. In case of need remove protection картера. It is necessary to start direct performance of procedures of service only after full cooling of the engine, i.e. after not less than several hours after trip end.
  2. Having waited definitive cooling of the engine, remove covers from a mouth of a broad tank.

If the engine has not completely cooled down yet, wrap up a cover rags for the purpose of risk elimination ошпаривания.

  1. For release of a cooling liquid from a radiator remove a stopper and connect a piece of a suitable hose to a drain branch pipe in the right bottom part радиаторной assemblages.
  1. Track, that the piece of a hose tense on the gate has been lowered in the prepared capacity. If the stopper "has become attached", or is not provided absolutely not, disconnect from a radiator the bottom hose and merge a liquid through it.

Cooling liquid should be lowered in drain capacity of the corresponding volume which it is necessary to prepare in advance. Try not to admit antifreeze hit in eyes and on open sites of a skin.

  1. If in the block of cylinders it is not provided the drain stoppers, full removal of a liquid from system is not obviously possible and the given fact should be taken into consideration at configuration of a fresh mix.
  2. While the liquid merges from the block, disconnect a hose from a broad tank and remove last. Wash out a tank pure water (in case of need - with soap). Clear уровневые labels on tank walls.
  3. Check up a condition радиаторных hoses and hoses of system of heating, and also collars of their fastening on unions and branch pipes (Routine maintenance see the Head).
  4. Replace the damaged components (in case of need see the Head of System of cooling, heating).

Washing

The radiator is washed out separately from system for the purpose of prevention of risk of blocking of thin internal channels of its heat exchanger as a result забивания by their adjournment which are washed away from a water shirt of the engine.

It will be separately reasonable to wash out the heater heat exchanger also.

 PERFORMANCE ORDER

  1. Disconnect the top hose from a radiator the top and bottom hoses and insert into a branch pipe of the first a garden hose. Include water delivery and continue washing until the pure transparent stream will not start to follow from the bottom branch pipe.
  2. In cases of especially strong pollution or infringement of passableness of a radiator remove last (Removal and installation of a radiator of system of cooling see) and make it обратнопоточную 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 workshop of car-care centre for carrying out of necessary regenerative repair.
  3. 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.

  1. For washing of a water shirt of the engine remove the thermostat (Removal, installation and check of serviceability of functioning of the thermostat see) and disconnect the bottom hose from a radiator.
  2. Fill a garden hose in an aperture under thermostat installation in a head of cylinders, include water delivery and continue washing until the transparent stream will not start to follow from the bottom hose.
  3. On termination of washing, establish the thermostat (Removal, installation and check of serviceability of functioning of the thermostat see) and restore initial connection of hoses.

Refuelling

 PERFORMANCE ORDER

  1. Check up serviceability of a condition and reliability of fastening of all hoses охладительного a path. Replace defective components, tighten collars.
  2. Translate the handle of management of system of heating of salon on the maximum heating.
  3. Uncover a broad tank and start to fill in slowly a fresh mix of antifreeze with water in a mouth of the last. Continue refuelling until liquid level in a tank will not rise to mark KALT/COLD the translucent case of the last. For release of air stoppers some times compress радиаторные hoses.

If the engine has not been completely emptied because of absence of drain stoppers, at first it is necessary to fill in in system pair of litres of the distilled water and only then to fill in a mix of demanded structure (or at first antifreeze, then - again water in demanded proportions).

  1. Establish into place a cover of a broad tank.
  2. Start the engine and allow to it to get warm to normal working temperature, then muffle and wait full cooling.
  3. Examine components of system of cooling on presence of signs of development of leaks, then check up level of a cooling liquid in a broad tank, in case of need make corresponding updating.
  4. Tighten a cover of a broad tank.
  5. At a corresponding complete set establish protection картера.
  6. Translate handles of a choice of temperature of submitted air and a choice of a high-speed mode of the fan on the maximum productivity.
  7. Start the engine, warm up it to normal working temperature.
  8. In summary make one more control check of level of a liquid (Routine maintenance see the Head).
