Amplifier Diaphragm
2. Remove the air filter assembly.
3. Turn off all accessories and disconnect the electric fan.
4. Plug and plug the coolant compensator hoses. stroke, valves and temperature sensor.
5. Warm up the engine to normal operating temperature and attach a tachometer.
Air Conditioned Models
6. Disconnect the vacuum pipe (B - in the accompanying illustration).

B - Vacuum tube
7. Apply vacuum from the collector to the diaphragm of the amplifier and make sure that the frequency is cold. engine speed increased to 1200 -1400 rpm. If this increase does not occur, turn the adjusting screw to adjust.

Models equipped with power steering
8. Follow steps 2-4. On air-conditioned models, also check and adjust the booster diaphragm.
9. From connect the vacuum pipe (A - in the accompanying scheme) and apply vacuum from the manifold to the amplifier diaphragm.

10. Engine speed should increase to 800-1000 rpm on manual transmission models and to 1050-1250 rpm on automatic transmission models. If the speed increase is not the same, disconnect the vacuum pipe and turn the adjusting screw on the diaphragm to adjust.

11. Reconnect the vacuum pipe and recheck the engine speed.
Triple solenoid valve
12. A triple solenoid valve is installed between the intake manifold and the booster diaphragm. On air-conditioned models, a triple solenoid valve limits the vacuum flow according to a signal sent through the control unit from the air-conditioning switch. A triple solenoid valve on power steering models limits vacuum flow according to a signal from the power steering switch.

And - the Steering drive with the amplifier; B - No. 2 ACV; C - Air conditioning
13. At idle, turn on the air conditioner and check that the booster diaphragm, triple solenoid valve are working properly.
14. Turn off the air conditioner and turn the steering wheel to the maximum angle to the right or left and check that the booster diaphragm, triple solenoid valve are working properly.
Amplifier Diaphragm Rod (arrow) should move if the triple solenoid valve is working properly
Power steering switch
15. Disconnect the power steering switch connector and check for an open as shown in the accompanying illustration. At idle, turn the steering wheel to the maximum angle to the right or left to make sure there is no break.
