5.3.1. Service of the cooling system (depletion, washing and filling)

Do not allow hit of antifreeze on open parts of the body and the painted surfaces of the car. Immediately wash away casual splashes a plentiful amount 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 stored in leaky closed container and immediately collect the 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. Do not merge old cooling liquid in the sewerage and on the earth at all!

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 the Head Nastroyki and routine maintenance of the car), the cooling system has to be emptied, washed out and be filled with fresh mix of antifreeze with water. Such service allows to prevent development of corrosion in a cooling 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 has to be checked (see the Head Nastroyki and routine maintenance of the car). Defective components are subject to replacement.

Do not forget about precautionary measures which have to be observed at service of the cooling system.

Depletion

 PERFORMANCE ORDER

  1. Cock the parking brake and prop up wheels antiretractable boots. In case of need remove protection of a case. It is necessary to start direct performing procedures of service only after full cooling of the engine, i.e. not less than several hours later after end of a trip.
  2. Having waited for final cooling of the engine, uncover a mouth of a broad tank.

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

  1. For production of cooling liquid from a radiator disconnect the lower hose from a radiator and merge liquid through it then connect a hose to a radiator and tighten a hose collar.

Cooling liquid should be lowered in the drain capacity of the corresponding volume which needs to be prepared in advance. Try not to allow hits of antifreeze in eyes and on open sites of skin.

  1. If drain traffic jams are not provided in the block of cylinders, full removal of liquid from system is not possible and this fact has to be taken into account at configuration of fresh mix.
  2. While liquid merges from the block, disconnect a hose from a broad tank and remove the last. Wash out a tank clear water (in case of need - with soap). Clear-level tags on tank walls.
  3. Check a condition of radiator hoses and hoses of system of heating, and also collars of their fastening on unions and branch pipes (see the Head Nastroyki and routine maintenance of the car).
  4. Replace the damaged components (in case of need see the Head of the Cooling system of the engine, heating of salon and air conditioning).

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 clogging 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 lower hoses and insert a garden hose into a branch pipe of the first. Include water supply and continue washing until the pure transparent stream does not begin to follow from the lower branch pipe.
  2. In cases of especially strong pollution or violation of passability of a radiator remove the last (see the Section Removal and installation of a radiator of the cooling system) and make its obratnopotochny washing, having filled a garden hose in the lower branch pipe, - if it is not possible to achieve positive result, deliver a radiator in a workshop of car service for carrying out necessary recovery repair.
  3. Products of corrosion and dense deposits are removed from a path of the cooling system by chemical processing, - follow instructions of manufacturers of the cleaner acquired by you.

At regular performing 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 the Section Removal, installation and check of serviceability of functioning of the thermostat) and disconnect the lower hose from a radiator.
  2. Fill a garden hose in an opening under installation of the thermostat in a head of cylinders, include water supply and continue washing until the transparent stream does not begin to follow from the lower hose.
  3. Upon completion of washing, install the thermostat (see the Section Removal, installation and check of serviceability of functioning of the thermostat) and restore initial connection of hoses.

Gas station

 PERFORMANCE ORDER

  1. Check serviceability of a state and reliability of fastening of all hoses of a cooling path. Replace defective components, tighten collars.
  2. Transfer the handle of management of system of heating of salon to the maximum heating.
  3. On OHC 1.2 and 1.4 engines of l separate the socket of the sensor switch of temperature and turn out the sensor from the inlet pipeline. Fill in OZh in the tank so that its level reached the lower cut of an opening of the sensor of temperature.

Temperature sensor switch socket

  1. On DOHC 1.4 and 1.6 engines of l turn out the screw with a head under a prutkovy six-sided key from the case of the thermostat and fill in OZh in the tank so that its level reached the lower cut of an opening of the sensor of temperature. Screw the screw with a head under a hexagon, having greased it with sealant (for example, OPEL 15 03 166), and tighten 15 Nanometers with effort.

The control screw in the thermostat case

On DOHC 1.0 and 1.2 engines of l there is no union for removal of air. Air quits the system itself during the operation of the engine.

  1. Uncover a broad tank and begin to fill in slowly fresh mix of antifreeze with water in a mouth of the last. Continue gas station until liquid level in a tank does not rise to the mark KALT/COLD the translucent case of the last. For release of air traffic jams several times squeeze radiator hoses.

If the engine was not completely emptied because of lack of drain traffic jams, at first it is necessary to fill in in system couple of liters of the distilled water and only then to fill in mix of the required structure (or at first antifreeze, then - again water in the required proportions).

  1. Establish into place a cover of a broad tank.
  2. Start the engine and let's it get warm up to the normal working temperature, then muffle and wait for full cooling.
  3. Examine cooling system components on existence of signs of development of leaks, then check the 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 the choice of temperature of the given air and the choice of the high-speed mode of the fan to the maximum productivity.
  7. Start the engine, warm up it up to the normal working temperature.
  8. In conclusion make one more control check of level of liquid (see the Head Nastroyki and routine maintenance of the car).
