Check of pressure of oil and the pressure gauge
The manometre is necessary for check with its possibility вворачивания in the gauge of pressure of oil. The pressure gauge is on the holder of the oil filter or near to the holder. Check
|
|
Check up oil level in the engine, if necessary, add.
Warm up the engine to working temperature. For this purpose pass on the car until the radiator fan will not join, and then again will not be switched off.
The diesel engine of 1.9 l: Remove the top cover of the engine, address to Section Removal and installation of the top cover of the engine / the bottom protection of an impellent compartment/stretcher.
|
Turn out the gauge of pressure of oil (2) on a flange of the oil filter and screw the device for check ().
|
|
Screw the device instead of the pressure gauge in the holder of the oil filter.
Connect a brown wire (1) devices to weight (-).
Attach control диодную a lamp to positive contact of the battery () and to the relay of pressure of oil. The light-emitting diode should not light up.
If the light-emitting diode lights up, replace the relay of pressure of oil.
|
|
If the light-emitting diode does not light up
|
|
Start the engine.
|
|
During starter start watch a light-emitting diode since the point of inclusion of the gauge of pressure can be passed already at start. |
The petrol engine: At pressure of oil 1.2 – 1.6 атм. The light-emitting diode should light up, otherwise it is necessary to replace the pressure gauge.
The diesel engine of 1.9 l: At pressure of oil 0.55 - 0.85 атм. The light-emitting diode should light up, otherwise it is necessary to replace the pressure gauge.
The diesel engine of 2.5 l: At pressure of oil 0.75 – 1.05 атм. The light-emitting diode should light up, otherwise it is necessary to replace the pressure gauge.
|
|
Check of pressure of oil
|
|
Start the engine on single turns. Remove value of pressure of oil from the device and compare it to the value resulted in Specifications.
Increase number of turns to 2000 rpm. Consider value of pressure of oil from the device and compare it to the value resulted in Specifications.
|
|
If demanded value of pressure of oil is not reached
|
|
Check up presence of mechanical damages to the engine, for example, damage of bearings of a cranked shaft (work HUNDRED).
If necessary, replace the holder of the oil filter with a safety valve or the oil pump.
|
|
At increase of number of turns of the engine of pressure of oil should not exceed 7.0 атм. Otherwise check up oil channels. If necessary, replace the holder of the oil filter with a safety valve. |
The diesel engine of 1.9 l: Establish into place the top cover of the engine.
