Tip: The throttle assembly can be removed without draining the coolant. To do this, you will need two M10 bolts as plugs.
Warning! Work should only be started after the engine has cooled to a safe temperature (not higher than 45°C).
Note: Removal of the throttle assembly is shown on engine 21114. On other engines, the work is performed similarly.
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. On engines 2112, 21124 and 21114, remove the decorative engine cover (see "Engine trim - removal and installation").
3. By unscrewing the expansion tank cap, we release excess pressure in the engine cooling system.
4. Remove the air supply hose to the throttle valve (see "Throttle valve - drive adjustment").
5. Disconnect the throttle drive cable from the sector (see "Throttle - Drive Cable Replacement").
6. Disconnect the wiring harness from the throttle position sensor (see "Throttle Position Sensor - Checking and Replacing").
7. Disconnect the wiring harness from the idle speed control valve (see "Idle speed control valve - checking and replacing").
8. Using a Phillips screwdriver, loosen the clamps securing the crankcase ventilation hose (1), two coolant supply hoses (2) and the adsorber hose (3).
9. Remove the crankcase ventilation hose from the throttle body fitting.
10. Disconnect the adsorber hose from the throttle assembly.
11. Key by 13 mm we unscrew the two nuts securing the throttle assembly to the receiver flange.
12. Remove the throttle assembly from the studs and lift it above the expansion tank of the cooling system. Holding the throttle assembly in a raised position, remove the coolant supply hoses from the throttle body fittings.
Note: It is not necessary to disconnect the coolant supply hoses to replace the throttle body gasket.
13. Insert M10 bolts into the hoses. To prevent them from falling out, tighten the hose clamps.
14. On engines 21114 and 21124 we remove the sealing rubber ring from the groove of the receiver flange. We replace the damaged ring.

On engines 2111 and 2112 we remove the sealing gasket from the studs. We replace the damaged gasket.
Installation
We install the throttle assembly in the reverse order.
