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.

Regularly, according to the schedule of routine maintenance of the car (see. Specifications), 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. Head Routine maintenance). 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).

Oporozhneniye

 PERFORMANCE ORDER

  1. 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.
  2. Having waited final cooling of the engine, remove covers from a mouth of a broad tank.

If the engine yet completely cooled down, wrap up a cover rags for the purpose of elimination of risk of an oshparivaniye.

  1. For production of cooling liquid from a radiator remove a stopper and connect a piece of a suitable hose to a drain branch pipe in the right lower part of radiatorny assembly.
  1. Track, that the piece of a hose tense on the gate was lowered in the prepared capacity. If the stopper "became attached", or is not provided not, disconnect from a radiator the bottom hose and merge 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 allow antifreeze hits in eyes and on open sites of skin.

  1. If in the block of cylinders it is not provided the drain jams, complete removal of liquid from system is not obviously possible and this fact should be taken into consideration at configuration of a fresh mix.
  2. 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.
  3. Check a condition of radiatorny hoses and hoses of system of heating, and also collars of their fastening on unions and branch pipes (see. Head Routine maintenance).
  4. Replace the damaged components (in case of need see. 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 of a zabivaniye by their deposits which are washed away from a water shirt of the engine.

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

 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 supply 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 violation of passableness of a radiator remove the last (see. Removal and installation of a radiator of system of cooling) also 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.
  3. 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.

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

Filling

 PERFORMANCE ORDER

  1. Check serviceability of a condition and reliability of fastening of all hoses of an okhladitelny path. Replace defective components, tighten collars.
  2. Transfer the handle of management of system of heating of salon to 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 filling until liquid level in a tank will not rise to KALT/COLD mark the translucent case of the last. For release of air jams several times compress radiatorny hoses.

If the engine was not completely emptied because of lack of drain jams, at first it is necessary to fill in in system couple of liters 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 let's to it get warm to normal working temperature, then muffle and wait complete cooling.
  3. 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.
  4. Tighten a cover of a broad tank.
  5. At the corresponding complete set establish protection of a case.
  6. 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.
  7. Start the engine, warm up it to normal working temperature.
  8. In summary make one more control check of level of liquid (see. Head Routine maintenance).
