Removal

The procedure for removing the manifold is similar to that described above, taking into account the following points:

• the vacuum and coolant hoses and electrical wiring vary depending on the model. When disconnecting any pipes, hoses, or wires, take into account their location to ensure proper installation in the same place;
• ignore references to air intake and starter hanger;
• any removed gaskets must be replaced.
