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.
