Removing
The component layout in the accompanying illustration will make it easier to follow the procedures described below. The air cleaner in the illustration has been removed.
1 - throttle cable; 2 - inlet pipeline; 3 - fuel vapor separator; 4 - temperature sensitive valve
1. Disconnect the negative cable from the battery.
2. Remove the air cleaner and disconnect the fuel supply and return hoses from the fuel vapor separator.
3. Empty the cooling system.
4. Loosen the clamps and disconnect the upper radiator hose and heating hose from the intake manifold.
5. Loosen nuts attaching to throttle cable bracket. Rotate the drive lever to fully open the shutter and remove the end of the cable from the holder. Take the cable to the side, removing it from the working area.
6. Disconnect the electrical wiring from the carburetor.
7. Disconnect a hose of the vacuum amplifier of brakes from the inlet pipeline.
8. Give bolts of fastening of an arm of the coil of ignition to the inlet pipeline.
9. Using a pipe wrench, disconnect the tubes of the valves of the exhaust gas recirculation systems (EGR) and VRT from the EGR valve.
10. On models equipped with air conditioning, disconnect the idle speed solenoid valve vacuum hoses from the throttle damper and intake piping.
11. Gradually, moving in a spiral from the ends of the inlet pipeline to its center, give the fixing bolts and nuts.
12. Trying to prevent dirt from entering the engine, carefully remove the intake manifold. Throw away the old gasket.
Installation
Installation is in the reverse order.
1. Thoroughly clean the mating surfaces and check their flatness. If necessary, make a groove in the pipeline.
2. Be sure to replace the sealing gasket.
3. In several stages, moving in a spiral from the center of the pipeline outward, tighten the fasteners with the required force.
4. Restore all original wiring, vacuum, fuel, and coolant line connections.
5. Prime the cooling system.
6. Start the engine and check for vacuum losses and fuel, oil and water leaks.
