Caution! If the manifold is disconnected only to remove the cylinder head, then unscrew the bolts and move it to the side without disconnecting the hoses and wires. The procedure for dismantling the manifold from the engine as a separate part is described below.
Removal
1. Disconnect the battery from ground.
2. Decompress the fuel system (see subsection 5.2.2)
3. Mark and disconnect the vacuum hoses from the manifold.
4. Remove the damper housing (see subsection 5.2.9.2.1) and an equalizing chamber (see subsection 5.2.9.2.6).
5. Remove the fuel distributor comb and injectors (see subsection 5.2.9.2.5).
6. Mark and disconnect the hoses from the recirculation valve and the modulating vacuum valve. Unscrew the recirculation tube from the manifold.
7. Disconnect the ground wire from the manifold (the connection point is indicated by an arrow).
8. Loosen the bolts and nuts (indicated by arrows) and remove the manifold.
Caution! Working from underneath the vehicle, disconnect the wire mounting brackets, lower bolts and 2 nuts securing the pair of steel tubes to the manifold.
Installation
1. Clean the manifold, check the condition of the split surface, and grind if necessary.
2. Install a new gasket, install the manifold and tighten the bolts and nuts.
3. Tighten the bolts and nuts evenly, to the specified torque, moving from the center to the periphery.
4. Install the remaining parts in reverse order.
5. Before starting the engine, check the throttle cable for free movement.
6. Start the engine and check for coolant leaks and vacuum connections.
