To remove the upper intake manifold, you need to disconnect various electrical connectors, hoses, and wiring harness retainers. Then, you should loosen the upper intake manifold bolts and remove it, discarding the upper-to-lower intake manifold seals. If necessary, remove the insulator from the left valve cover.

The initial steps are to relieve the fuel system pressure and disconnect the cable from the negative terminal of the battery.

Disconnect the negative battery terminals, disconnect the left intercooler tube from the EGR air flow control valve, remove the EGR crossover tube, disconnect interfering wiring harnesses, remove the oil dipstick tube bolts and intake manifold bolts, install a new gasket during reassembly, disconnect the fuel injector wiring harness and pressure sensor wiring harness, remove the air intake heater mounting bolts, lift off the heater assembly and discard the gasket, use new upper and lower heater block gaskets during reassembly, and replace the intake air heater relay by disconnecting the negative battery terminals, labeling and disconnecting the trigger wires, removing the nuts from the cable terminals, and removing the relay mounting bracket bolts.

You should remove the upper dipstick tube mounting bolt and detach the throttle and cruise control cables if necessary.

Detach the fuel rail from the dump/overflow valve, then remove it.
