Checking the recirculation valve of a diesel engine 1.9 l, 47 kW
1 - vacuum pump; 2 - connecting pipe; 3 - recirculation valve; 4 - valve membrane
Valve check
1. Remove the upper engine cover (see subsection 2.1).
2. Disconnect the vacuum hose from the valve fitting 3 (see fig. Details of the recirculation system of the diesel engine 1.9 l, 47 kW) recycling systems.
3. Connect to valve port 3 (see fig. Details of the recirculation system of the diesel engine 1.9 l, 47 kW) vacuum pump 1 (see fig. Checking the recirculation valve of a diesel engine 1.9 l, 47 kW).
4. Use a pump to create a vacuum in the valve. Diaphragm 4 of the valve should move up (can be checked by touch with your fingers from the bottom of the valve), and after disconnecting the vacuum pump, the membrane should return to its original position (can be identified by a clear sound). Otherwise, the valve is defective and must be replaced.
Removal and installation of elements of the recirculation system
1. Remove the upper engine cover (see subsection 2.1).
2. Disconnect the vacuum hose from the valve fitting 3 (see fig. Details of the recirculation system of the diesel engine 1.9 l, 47 kW) recycling systems.
3. Turn away two bolts 4 fastenings of the valve 3 of recirculation system to an inlet pipe 1 of the engine.
4. Unscrew the coupling bolt 6 of the clamp 5 and remove the valve 3 of the recirculation system from the connecting pipe 8.
5. To remove the connecting pipe 8 unscrew the two nuts 7 of its fastening to the exhaust manifold.
6. Replace gaskets 2 regardless of their condition.
7. Establish elements of system of recirculation of the fulfilled gases upside-down. Nuts 7 fastening the connecting pipe to the exhaust manifold, replace with new ones.
