Features of the device
Engines of cars Hyundai are equipped by circulating system of cooling. For circulation of a cooling liquid the centrifugal pump serves. The system of cooling of the engine consists of a shirt of cooling, a radiator with the electrofan, the centrifugal water pump, the thermostat and hoses. The cooling system works with a separate broad tank.
Management of a contour of a cooling liquid the thermostatic. While the engine cold, a cooling liquid circulates only in a head of the block of cylinders, the block of cylinders and the heat exchanger. In process of warming up of the engine the thermostat opens the big contour of system of cooling. The cooling liquid starts to move constantly working pump through a radiator of system of cooling. The cooling liquid passes through a radiator from top to down, being cooled passing between plates of a radiator air.
When the temperature of a cooling liquid is in a range 92–97 °С, the thermoswitch includes the radiator electrofan. The electrofan is put in action by the electric motor and works until the temperature of a cooling liquid will not fall more low 84–91 °С.
|
THE PREVENTION
Be cautious – the radiator electrofan can join and at the switched off ignition. Because of heat in a motor compartment it can occur some times.
|
Thanks to that that the fan works changeably, useful capacity of the engine increases, the fuel expense decreases.
The beskorpusnyj thermostat of system of cooling – with firm thermosensitive наполнителем.
Radiator of system of cooling trubchato-lamellar, aluminium, with plastic tanks. The cooling liquid is filled in in system through a bulk mouth of the broad tank which stopper is supplied inlet and final by valves.
Cars with engines in working volume of 1,1 and 1,3 l
Check of tightness of system of cooling
Wait, while the engine will cool down, then cautiously remove a radiator stopper.
Check up level of a cooling liquid (should be at the bottom edge of a mouth of a radiator).
Establish on a mouth of a radiator the adaptation for check of stoppers of a radiator and create in system pressure 140 кПа (1,4 kgs/sm 2). Supporting the specified pressure during 2 mines, be convinced of absence of leaks of a liquid from system, through hoses and connections.
In the presence of liquid leaks eliminate them or replace faulty details.
|
THE NOTE
The temperature of a cooling liquid can be very high. Do not open cooling system on the hot engine as thus there can be an emission of a hot liquid that will cause burns. Start works with cooling system only after engine cooling.
|
Dry wipe checked knots and connections of system of cooling.
At removal of the verifying adaptation watch that from it the cooling liquid has not poured out.
At installation, check and removal of the verifying adaptation try not to deform a radiator mouth.
Check of a stopper of a radiator of system of cooling
Remove a radiator stopper, moisten a lining of a stopper with a cooling liquid and establish a stopper on the adaptation for check (fig. 2.89).
Create the adaptation pressure until the arrow of a manometre of the adaptation will cease to deviate.
|
THE NOTE
Pressure of opening of the steam valve – 78–108 кПа (0,8–1,1 kgs/sm 2).
Maximum permissible value – 65 кПа (0,66 kgs/sm 2).
|
Be convinced that opening of valves occurs at pressure not less specified.
If opening of valves begins at smaller pressure, replace a radiator stopper.
|
THE NOTE
Before check be convinced of cleanliness of a stopper of a radiator: if on a stopper lining there are traces of a rust or other pollution, results of check will be inexact.
|
Replacement of a cooling liquid
It is necessary to replace cooling liquid only after repair of system of cooling at which the liquid merged. Replacement within the limits of annual maintenance service is not provided. If at repair the head of the block of cylinders, a lining of a head of the block of cylinders, a radiator, a radiator of a heater or the engine were replaced, in any case it is necessary to replace cooling liquid. It is required for the reason that anticorrosive particles in a phase extra earnings, settling on details of system of the cooling, the easy metals made of alloys, provide creation of a durable anticorrosive layer. The share of anticorrosive particles in the liquid which was in the use not so is great to create on new details a sufficient protective layer.
|
PREVENTIONS
It is impossible to use repeatedly merged cooling liquid – it is poisonous. It cannot be poured out simply in the water drain or on the earth. Utilise cooling liquid in places specially taken away for this purpose.
At plum of a cooling liquid watch that the cover of the block of the relay has been closed, do not suppose liquid hit on elements of an electric equipment and a paint and varnish covering of a body. If the liquid spills, at once смойте its considerable quantity of water.
|
Establish the handle of the switch of temperature in the position corresponding to the maximum temperature of air submitted to salon. Be convinced that the engine and a radiator to the touch the cold.

Stop the engine. Check up and if necessary restore to norm liquid level in a radiator.
Tighten a radiator stopper, then start up the engine and be convinced of absence of leaks.
Check of density of a cooling liquid
The cooling system should be all year long filled by a solution этиленгликоля in water that prevents the damages caused by freezing and corrosion, formation of limy adjournment and, besides, increases a boiling point of a cooling liquid. In a contour of system of cooling
Because of liquid expansion at heating superfluous pressure is created that also promotes increase of a boiling point of a liquid. Pressure is limited by the valve in a cover of a broad tank. Higher boiling point of a cooling liquid is necessary for normal work of system of cooling. At too low boiling point in system steam stoppers because of what damage of a cooling contour and reduction of cooling of the engine is possible can be formed. Therefore the cooling system should be all year long filled by antifreeze.
As a cooling liquid antifreeze on a basis этиленгликоля for details from aluminium alloys can be used only.
|
THE NOTE
Level of a cooling liquid is recommended to be checked on the cold engine as at heating its volume increases and in the heated-up engine liquid level can rise considerably.
|
Remove a radiator stopper.
Check up ареометром density of a cooling liquid which should be 1,078–1,085 g/sm 3.
If level in a tank below norm, and density of a liquid above specified, add the distilled water. If density normal, add a liquid of the same mark, as a liquid which is in system of cooling. When density below norm, restore its concentrate.
|
PREVENTIONS
At concentration of antifreeze below 30 % anticorrosive properties of a cooling liquid decrease.
At concentration above 60 % frost resistance and cooling properties of a liquid decrease that negatively influences engine work. Therefore it is necessary to support concentration этиленгликоля in the specified limits.
Do not mix cooling liquids of different marks.
