Removal
1. Relieve the pressure in the fuel system (see chapter 4). Disconnect the negative cable from the battery.
Warning. If your car is equipped with an anti-theft audio system. before disconnecting the battery, make sure that Ves has the unlock code.
2. Drain the coolant into a clean container (see chapter 1).
3. Remove the air inlet duct (see chapter 4).
4. At the throttle body, disconnect the throttle actuator, hoses and electrical connectors. The valve body may remain bolted to the manifold. Disconnect the crankcase ventilation hose from the intake manifold.
5. Mark and then disconnect all wires. hoses and brackets attached to the intake manifold (figure 8.5,a,6).
6. Disconnect the high-voltage wires from the spark plugs and unhook them from the holders. Leave the wires connected to the ignition distributor.
7. The injectors may remain in the manifold. but you need to disconnect the fuel supply line, electrical connectors and the fuel pressure regulator vacuum hose from them (see Figure 8.5.a).
8. At the rear of the manifold, disconnect the electrical connectors for the variable manifold configuration control system. Tag and disconnect the vacuum hoses and coolant hoses attached to the manifold (see Figure 8.6). Proceed slowly and carefully. Access to the space behind the manifold is difficult and not all hoses are visible. Do not attempt to remove the manifold until you are sure all hoses are disconnected.
9. Unscrew the nuts and bolts securing the manifold to the lectricians and remove the manifold from the engine (figure 8.9). Do not try to pry the manifold off if it is stuck to the gasket.
Installation
10. Scrape off any remaining old gasket and sealant from the mating surfaces of the manifold and cylinder heads, then wash the surfaces with nitro solvent or acetone.
11. The connecting pipe of the cooling system passes under the manifold (figure 8.11). Due to the difficulty of accessing this area, you need to take advantage of the fact that the manifold is removed and replace the hose and its clamps.
12. Place new gaskets on the cylinder heads (figure 8.12) and install the manifold. Be careful not to move the gaskets. Secure the collector with bolts and nuts.

13. Tighten the nuts and bolts in several steps until the specified torque is reached. Tighten the fasteners from the middle to the ends of the manifold.
14. Install the remaining parts in the reverse order of removal.
15. Fill the cooling system. Start the engine and check for fuel, coolant, and vacuum leaks.
