    1. Disconnect the negative battery cable. Relieve the fuel system pressure.
    2.  


    CAUTION
    Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

    1. Drain the cooling system.
    2.  
    3. Tag and unplug the wiring from the Mass Air Flow (MAF) sensor and the Intake Air Temperature (IAT) sensor.
    4.  
    5. Remove the air cleaner outlet tube. Remove the air cleaner bolts at the air cleaner body.
    6.  
    7. Disconnect the engine intake air resonator by pushing in the top and bottom tube surfaces at the engine air cleaner and pulling the air cleaner outward. Lift the air cleaner up and out of the engine compartment.
    8.  
    9. Remove the fuel line safely clips. Disconnect the fuel supply and return lines from the fuel supply manifold using the proper disconnect tools.

    12.  

    Note the position of the CMP sensor electrical connector. The installation requires that the connector be located in the same location.

    1. With suitable pliers, slide back the upper radiator hose clamp and with a twisting motion loosen the hose from the hose connection.
    2.  
    3. Remove the upper intake manifold.
    4.  
    5. Loosen the EGR tube nut and remove the EGR valve to exhaust manifold tube from the EGR valve tube to manifold connector.

    Fig. Fig. 20: Exploded views showing lower intake manifold gasket and seal installation and points where sealant should be used-3.0L OHV engines

    1. Clean the gasket mating surfaces of the intake manifold and the cylinder heads. Lay a shop rag in the lifter valley to catch any gasket material. After scraping, carefully lift the shop rag from the lifter valley, being careful not to let any particles enter the oil drain holes or cylinder head. If necessary, use a suitable solvent to remove old rubber sealant.
    2.  
    3. Lightly oil all the attaching bolts and stud threads before installation. When using a silicone rubber sealer, assembly must occur within 15 minutes after the sealer has been applied. After this time, the sealer may start to set-up and its sealing quality may be reduced. In high temperature and/or humidity conditions, the sealant will start to set up in approximately five minutes.
    4.  
    5. Apply a 1 / 4 inch (5-6mm) bead of a suitable silicone rubber sealer to the intersection of the cylinder block end rails and cylinder heads. Be careful not to let sealer that may block oil passages fall into the engine.

    7. Install the front and rear intake manifold end seals in place and secure. Install the intake manifold gaskets, aligning the locking tabs to the provisions on the cylinder head gaskets.
    8.  
    9. Carefully lower the intake manifold into position on the cylinder block and cylinder heads to prevent smearing the silicone sealer and causing gasket voids.
    10.  
    11. Install bolts 1, 2, 3 and 4and hand tighten
    12.  
    13. Install the bolts and tighten in the sequence illustrated in two steps. On the first pass tighten to 15-22 lbs. (20-30 Nm). On the second pass tighten the bolts in sequence to 20-23 ft. lbs. (26-32 Nm).
