GENERAL INFORMATION

The system of cooling of the tight type also includes an electric heater, a wide tank, the bomb of cooling the liquid, the thermostat and the ventilator.

In cars with the auxiliary alarming system, the wide tank contains the sensor of a longitudinal list of the car that includes a lamp of the alarming system if the level of cooling liquid considerably to fall.

In the departure of the cooling of cold motor the liquid circulates around the cylinder block, a head (heads) of the cylinder block and a final collector. The liquid of hot cooling passes by a covering of the automatic air door (in the presence) and by a heater before the return to the motor.

When the liquid that cools stretches out, the level of a wide tank increases. The entry of cooling the liquid for an electric heater closes what supplies the shut thermostat. When it cools liquid get the predetermined temperature, the thermostat opens and the liquid of hot cooling passes by the best hose to an electric heater. Like the liquid that cools it passes by an electric heater I lower, there is his cooling with a current of opposite air. The circulation of cooling the liquid continues for a wide tank, a final collector and a heater constantly.

The hydraulic union of the supporter is the air temperature made work behind an electric heater. When the air temperature gets the predetermined level, the spiral bimetálica opens the valve and liquid movements of silicon for the system of blades of the union. The main part of the union is located in an end with the water bomb, the driven part of the union is joined with supporter's shovels. The blades of the union are arranged so that the torque was transferred to supporter's shovels depending on the viscosity of liquid that to his time depends on the surrounding temperature and the frequency of the rotation of the motor. Therefore, the supporter only works when one needs and in comparison with the supporter constantly of work considerably safe the fuel, reduces the use of a belt of driving and the noise of the supporter.

Electric heater and wide tank

The electric heater with an angry current has tanks of the artificial material. The wide tank is done from the transparent material and has designations of the maximum and least levels of cooling the liquid. In the equipped cars of the automatic exchange in the right tank of an electric heater the electric heater of oil of the automatic exchange is located (type the liquid that cools the oil).

The wide tank with the valve of the excessive pressure that effectively pressuriza the cooling system so much in the temperature increase of cooling the liquid, as in the moment of the reduction. The wide tank also has the function of decontaminação. Any accumulation of air blisters in the cooling of liquid, in case of the thermostat and an electric heater returns to a wide tank and give out in the atmosphere, so the operational efficiency of cooling the liquid supports itself.

In cars with the auxiliary alarming system the wide tank contains the sensor of a longitudinal list of the car that includes a lamp of the alarming system if the level of cooling liquid considerably to fall.

Pressure of opening of the valve of excessive pressure in a cork of a wide tank:
  – OHC and driving DOHC
85 - 110 kPa
  – Motor of V6
100 - 140 kPa

Bomb of cooling the liquid

The centrifugal bomb of cooling the liquid located in an advanced wall of the cylinder block puts itself in the action for a side belt together with the creator.

Side belt

Mark and type
Motorcraft 83 HF 6 C 301 AA
The tension (measured by adaptation of special Ford):
  – new belt
400 - 500 N
  – the belt that was in the use
300 - 400 N
Deflexão
10 mm in the middle of longer siege below pressure of a thumb

Supporter

The ventilator of the motor OHC is manufactured of the artificial material, have seven blades, locate in an end of the bomb of cooling the liquid and it puts itself in the action for a side belt together with the bomb and the creator.

The supporter of motor DOHC with the electric walk of the thermal sensor is located in a cork of drain of an electric heater.

Thermostat


The thermostat is located behind a tube of branch of water production in the advanced party of a head of the cylinder block in the models OHC and in an advanced part of the water bomb in the models V6.

The temperature began to open:
  – OHC and driving DOHC
85 - 89 °C
  – Motor of V6
79 - 83 °C
Nominal opening temperature
88 °C
Temperature of full opening
102 ± 3 °C

Liquid cooling

Quantity:
  – Motor of OHC
8,0 dm3
  – the motor DOHC with the carburator
7,9 dm3
  – the motor DOHC with injection system
7,3 dm3
  – Motor of V6
8,5 dm3
To type
the mixture of the special non-congelation liquid of Ford SSM 97 B 9103 A and the distilled water (in 50 %) it forms a-30 °C
