EGR valve installation details on petrol models with 112 and 113 series engines
19 - Inlet pipeline; 89 - EGR valve; 89/1 - EGR pipe; 89/2 - Vacuum control unit; 89/3 - Union nut; a - Vacuum from the intake pipeline; b - Depression of controlled depth from the transducer of the recirculation system to the EGR valve; Y31/1 - Vacuum EGR transducer
1. Details of installing the EGR valve on models equipped with 112 and 113 series engines are shown in the illustration, which includes all references in the text.
2. Remove the air cleaner cover.
3. Remove the intake air duct assembly with the MAF sensor.
4. Give the union nut (89/3) on the EGR valve (89).
5. Disconnect the EGR pipe (89/1) from intake manifold (19) and cylinder heads.
6. Disconnect wiring harness from EGR transducer (Y31/1).
7. Remove the EGR valve (89).
8. Installation is carried out in the reverse order - in order to avoid jamming of the throttle actuator lever, make sure that the vacuum tube from the EGR transducer is correctly routed (Y31/1).
