Removal
The component layout diagram in the accompanying illustration will assist you in performing the following procedures. The air cleaner is removed in the illustration.
1 - throttle cable; 2 - inlet manifold; 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. Drain the cooling system.
4. Loosen the clamps and disconnect the upper radiator hose and heater hose from the inlet manifold.
5. Loosen the nuts securing the throttle cable to the bracket. Turn the drive lever to fully open the throttle and remove the cable end from the holder. Move the cable to the side, removing it from the work area.
6. Disconnect the electrical wiring from the carburetor.
7. Disconnect the brake booster hose from the intake manifold.
8. Remove the bolts securing the ignition coil bracket to the intake manifold.
9. Use a pipe wrench to disconnect the exhaust gas recirculation (EGR) and ART valve tubes from the EGR valve.
10. On models equipped with air conditioning, disconnect the idle speed control solenoid vacuum hoses from the throttle damper and intake manifold.
11. Gradually, moving in a spiral from the ends of the intake manifold to its center, loosen the mounting bolts and nuts.
12. Carefully remove the intake manifold, being careful not to allow dirt to enter the engine. Discard the old gasket.
Installation
Installation is carried out in reverse order.
1. Carefully clean the mating surfaces and check their flatness. If necessary, regrind the pipeline.
2. Be sure to replace the sealing gasket.
3. In several steps, moving in a spiral from the center of the pipeline outward, tighten the fasteners to the required force.

4. Restore all original electrical, vacuum, fuel and coolant line connections.
5. Fill the cooling system.
6. Start the engine and check for vacuum losses and fuel, oil and water leaks.
