Removal

Detachment of a returnable spring of a butterfly valve from an arm on an inlet collector

Unscrewing of nuts of fastening of the case of a throttle

Removal of the case of a throttle on the SOHC models

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Weaken the collars, fixing the main air branch pipe to the case of a throttle and a measuring instrument of a stream of air and remove a branch pipe.
3. Weaken a collar and disconnect a hose of a regulator of turns of idling from the throttle case.
4. Disconnect a hose of ventilation of the case, going from a cover of a head of the block of cylinders to the throttle case.
5. Disconnect hoses of giving I cool liquid Russian cabbage soup from the case of a throttle and close the ends of hoses suitable jams for reduction of loss I cool liquid Russian cabbage soup.
6. Disconnect the electric socket from the sensor of provision of a butterfly valve.
7. Remove an accelerator cable from the butterfly valve lever.
8. Take a sealing ring of a cover of a cable of an accelerator from an arm on an inlet collector, then отсоеди threads a returnable spring of a zaslonka from an arm (see fig. A detachment of a returnable spring of a butterfly valve from an arm on an inlet collector).
9. Check that all hoses and электричес cues sockets are disconnected from the throttle case.
10. Unscrew four nuts and remove the throttle case from an inlet collector (see fig. Unscrewing of nuts of fastening of the case of a throttle, Removal of the case of a throttle on the SOHC models). For access to the bottom nuts of fastening of the case of a throttle move fuel hoses aside.
11. Remove laying of the case of a throttle.
12. If necessary remove from the throttle case the sensor of provision of a butterfly valve.

Installation

Installation of laying of the case of a throttle

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments.
2. If acted in film, establish the sensor of provision of a butterfly valve.
3. Establish the throttle case with использо a vaniye of new laying (see fig. Installation of laying of the case of a throttle).
4. Check correctness and reliability of connection of hoses and electric sockets.
5. Check level of cooling liquid and, if necessary, finish it to norm.
If necessary adjust an accelerator cable.
