To release the components, the following steps have to be followed, firstly, the cowl cover has to be detached, then the cowl support brace and finally the windshield wiper motor support bracket. Stand back from the fuel pump and release the pressure off the fuel system and remove the connection of the negative terminal of the car battery. Then, take out the air filter housing and intake air duct and at least, unbolt the ignition coils. Remove the brake booster vacuum hose and the PCV hose and then remove fuel rail and the injector assembly. Remove the alternator and the air conditioning compressor, so that they are not connected anymore with the refrigerant lines, but still at hand. Remove the electrical connections from the IAT, MAP, TPS and ECT sensor leads. First unravel the intake manifold bolts from the external to the internal starting a 1/4 turn at one time until it could be easily unstucked, remove the intake manifold where any elements sticking to it will have to be detached as the intake manifold is pulled off. For installation; make sure that the surfaces of the cylinder heads as well as the intake manifold surfaces of the engine are clean. Any signs of wear on the O-rings on the intake manifold go for a new set of one but make sure to fit correctly. Gently install the manifold in position without shifting the rubber rings or coming into contact with the cylinder heads after placing it in position as this will shift the rings and this will cause vacuum or oil leakage. Torque the intake manifold bolts in the proper sequence to the manufacturer-prescribed LB of force. Last, do the remaining installation procedures in sequence with removal, engage the engine and look for vacuum leaks especially at the intake manifold gasket.

Next, remove the ignition coils and fuel rails, and drain some coolant. On VB engines, remove the coolant temperature sensor.

After that, remove the engine cover by pulling up at the front and sliding it forward. Remove the air filter housing and the intake air duct.

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.

The initial steps to remove the intake manifold are relieving the fuel system pressure and disconnecting the negative battery cable.

Remove the clamps from both ends of the air transfer tube. Remove the bolt from the P-clip for the air conditioning line, then remove the air transfer tube.

Disconnect all electrical connectors for the intake manifold sensors, ignition coils, Idle Air Control motor, alternator, and air conditioning compressor.
