Folksvagen Sharan/Sharan repair>> System of greasing of the engine>> Check of pressure of oil It is necessary to know the following:
The 2,0-litre engine has the switch of pressure 5 (fig. 166) oils on 25 кПа (dark blue isolation) and the switch of pressure of 6 oils on 180 кПа (black isolation see);
- Engine VR6 has the switch of pressure of oil on 30 кПа (brown isolation) and the switch of pressure of oil on 140 кПа;
- Pressure of oil in the engine can be measured by means of a manometre with an adapter which is rolled instead of the switch of pressure of oil;
- On engines (2,0 l and VR6) one of switches of pressure of oil is connected to a control lamp of insufficient pressure of oil. At oil pressure drop more low 25 кПа (the engine 2,0) or 30 кПа (engine VR6) the switch of pressure of oil on 25 кПа and accordingly on 30 кПа is closed and thus the control lamp of insufficient pressure of oil lights up.
At the control it is necessary to check both switches.
Check of switches of pressure of oil spend in a following order:
- Check up and if necessary finish to norm oil level in the engine;
- Include ignition. The control lamp of pressure of oil thus should light up;
- Start the engine. The control lamp of pressure of oil should go out;
- Disconnect штекерную колодку from the switch of pressure of oil on 25 кПа or 30 кПа (it is defined on colour of isolation) and close the wire end on "weight". The control lamp of pressure of oil Should light up;
- Again put on штекерную колодку;
- Disconnect штекерную колодку from the switch of pressure of oil on 140 кПа or 180 кПа (it is defined on colour of isolation);
- Start the engine and allow to it to work at frequency of rotation more than 2000 mines-1. Should light up a control lamp of pressure of oil and work a sound signal.
Check of the switch of pressure of oil on 25 кПа or 30 кПа spend in a following order:
- Turn out switches of pressure of oil on 25 кПа or 30 кПа (it is defined on colour of isolation);
- Screw a manometre 1342 (fig. 176) instead of the switch of pressure of oil (on the 2,0-litre engine — in a head of the block of cylinders, on engine VR6 — in the filter basis);
- Connect a brown cable 1 (fig. 176 see) manometre to "weight";
- Connect the measuring device (a tester or диодную a verifying lamp) between the switch of pressure of oil on 25 кПа or 30 кПа and positive conclusion АБ. The control lamp or the light diode should light up;
- Start the engine and gradually increase frequency of rotation. As soon as the manometre will show 15—35 кПа (the engine 2,0) or accordingly 15—45 кПа (engine VR6), pressure should be equal 0, and the control lamp should go out. Otherwise replace the switch of pressure of oil on 25 кПа or 30 кПа.
Check of the switch of pressure of oil on 140 кПа or 180 кПа spend in a following order:
- Disconnect штекерную колодку from the switch of pressure of oil on 140 кПа or 180 кПа (it is defined on colour of isolation);
- Turn out the switch and screw a measuring instrument of pressure of oil;
- Connect the measuring device (a tester or диодную a verifying lamp) between the switch of pressure of oil on 140 or 180 кПа and positive conclusion АБ. The control lamp or the light diode should not burn;
- Start the engine and gradually increase frequency of rotation. Check up: on the 2,0-litre engine at pressure 160—200 кПа the control lamp lights up, and on engine VR6 the control lamp should light up at pressure 120—140 кПа. If it does not occur, replace the switch of pressure of oil;
- Increase frequency of rotation to 2000 mines-1 and check up, that the manometre showed a minimum 200 кПа (for VR6 and the 2,0-litre engine). Thus the oil temperature should be 80 ° C;
- If it not so replace or repair the oil pump. Pressure of oil should not be more than 700 кПа.
