Cars with 1.6-/2.0-liter petrol engines
The throttle body must be removed when performing many jobs in the engine compartment.
Removal
1. Remove the air filter.
2. Disconnect the connectors of the intake air temperature sensor 1 and the throttle opening potentiometer 8 (see illustration).
3.2 Disconnect the connectors of the intake air temperature sensor 1 and the throttle opening potentiometer 8
3. Loosen the screw clamp of the hose fastening clamp 2 on the throttle pipe and remove the hose(see illustration) 3.2).
4. Disconnect the accelerator cable from the throttle lever.
5. Disconnect the crankcase ventilation hose.
6. Clamp the cooling hoses 6 using clamps, for example HAZET 4590-2 or FACOM Mot. 453-01, at the points indicated by the line in Illustration 3.6. If this is not done, the cooling system will leak fluid after the next operation.
3.6 Clamp the cooling hoses 6 at the points marked with the line using clamps, e.g. HAZET 4590-2 or FACOM Mot. 453-01
7. Loosen the clamps on the hoses 6 and disconnect the hoses (see illustration 3.6).
8. Unscrew the four bolts (see arrows in illustration 3.6) and remove the throttle body.
Installation
9. Replace the flat sealing gasket between the throttle body and the intake manifold. Remove the old seal and also remove its remains from the sealing surfaces.
10. Secure the throttle body with four bolts. The tightening torque of the bolts is 15 Nm.
11. Connect the cooling system hoses and secure them to the pipes with clamps.
12. Remove the clamps from the hoses that were used to clamp them to prevent coolant leakage.
13. Connect the crankcase ventilation hose 5 (see illustration 3.2).
14. Connect the plugs of the intake air temperature sensor and throttle potentiometer.
15. Attach the accelerator cable to the throttle lever and adjust its tension.
16. Secure the air intake hose to the throttle body. The hose clamp screw should be on the side opposite the accelerator cable.
17. Replace the air filter.
18. Fill the coolant and bleed air from the cooling system.
