If you only need to remove the upper intake manifold, stop at this point. Otherwise, continue with the
procedure to also remove the lower intake manifold.
8. Drain coolant. Remove the upper radiator and heater supply hoses from intake manifold.
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are
quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless
it is contaminated or several years old.
9. Remove distributor cap and spark plug wires as an assembly.
10. Observe and mark the location of the distributor rotor and housing so ignition timing can be
maintained at reassembly. Remove distributor hold−down screw and clamp and lift out distributor.
11. Remove rocker arm covers.
12. Remove intake manifold attaching bolts and nuts. Note length of manifold attaching bolts during
removal so that they may be installed in their original positions. Tap manifold lightly with a plastic
mallet to break gasket seal. Lift off manifold.
13. Remove all old gasket material and sealing compound.
To install:
14. Apply sealing compound to the joining surfaces. Place the intake manifold gasket in position. Ensure
the tab on the right hand bank cylinder head gasket fits into the cutout of the manifold gasket.
