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 the measuring instrument of a stream of air and remove a branch pipe.
3. Weaken a collar and disconnect a hose of the regulator of turns of idling from the throttle case.
4. Disconnect the hose of ventilation of a 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 I cool with suitable traffic jams for reduction of loss 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 lever of a butterfly valve.
8. Take a sealing ring of a cover of a cable of an accelerator from an arm on an inlet collector, then otsoyed to Nita a returnable spring of the gate from an arm (see rice. A detachment of a returnable spring of a butterfly valve from an arm on an inlet collector).
9. Check that all hoses and электричес sockets are disconnected by Kia from the throttle case.
10. Unscrew four nuts and remove the throttle case from an inlet collector (see rice. 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 lower 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 the sensor of provision of a butterfly valve from the throttle case.

Installation

Installation of laying of the case of a throttle

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