Intake Manifold: Removal

  1. Place transmission gear selector in Park (Neutral on manual transmissions). Set parking brake and block drive wheels. Although fuel pressure drops to zero when ignition is turned off, loosen fuel filler cap to relieve tank pressure. To further minimize risk of fire and personal injury, cover surrounding areas with a shop rag while removing fuel lines.

  2. Disconnect negative battery cable. Remove engine cover and air injection crossover hose. Remove air cleaner. Drain cooling system. Label and disconnect necessary brackets, wires and hoses. Disconnect fuel lines and linkages.
