The intake manifold is a two−piece (upper and lower) aluminum casting. Runner lengths are tuned to optimize
engine torque and power output. The manifold provides mounting flanges for the air throttle body assembly,
fuel supply manifold, accelerator control bracket and the EGR valve and supply tube. A vacuum fitting is
installed to provide vacuum to various engine accessories. Pockets for the fuel injectors are machined to
prevent both air and fuel leakage. The following procedure is for the removal of the intake manifold with the
fuel charging assembly attached.
1. Make sure the ignition is off, then drain the coolant from the radiator (engine cold).
CAUTION
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.
