- Lubrication system


Lubricant under pressure is provided by the gear oil pump put in action from a cam-shaft via the angular tooth gearing the Lubrication system has the replaced filter and the oil heater.

Oil pump

The gear oil pump rotating with cam-shaft speed.

Width of gear wheels
29 mm
Oil pressure (at a temperature of 80 °C):
  – at 650 rpm 
0,12 MPas
 – at 3000 rpm
0,30 MPas

Oil filter

The disposable, replaced filter.

Brand and type: Motorcraft EFL 164 or Purftux LS 127.

Frequency of replacement: each 7500 km of a run or time in six months.

Oil pressure sensor

It is located in the holder of an oil filter.

Brand: Calorstat.

Temperature began opening: 72 °C.

Temperature of full opening: 81 °C.

Minimum valve stroke: 7,5 mm.


The fan is put in action by a maple belt by means of the electromagnetic coupling included by the thermal switch located in a radiator.

Number of blades: 8.

Outer diameter of blades: 360 mm.

Thermal switch of coupling of the fan

It is located in the right tank of a radiator.


  – inclusions: 82 °C;
  – switching off: 68 °C.

Cooling liquid

Quantity: 9,5 dm3.

Type: special nonfreezing Ford SQM97B9103A liquid.

Frequency of service: check of level each 7500 km of a run (does not demand periodic replacement of cooling liquid).
