Tips for a great answer:
Unscrew the bolt that holds the negative connection to the Impala's
battery. Set this bolt aside for later use.
Remove the engine cover to access the intake manifold and manifold
gasket. Disconnect the throttle body inlet duct from the engine.
Twist off the radiator cap to allow draining of the coolant to flow more
smoothly. Place an empty container beneath the radiator's drain plug, and
remove this plug. Allow all of the engine coolant to drain into the empty
container. Replace the drain plug once you are finished.
Tag all of the electrical wiring and hoses before removing so that
reconnection is precise to factory settings. Remove these parts, individually,
from the intake manifold.
Loosen the bolts that hold the intake manifold to the Impala's engine
block. Lift the intake manifold from the block once all bolts have been
Use the flat-head screwdriver to pry the old intake manifold gasket from
the engine block. Discard this part once you have removed it.
Clean the engine block thoroughly with the engine degreaser and linen
cloth. If necessary, use a gasket scraper to remove excess buildup and grime.

Reconnect all of the necessary hoses and electrical wiring to the
intake. Pour the engine coolant back into the radiator.
Reattach the engine cover on top of the intake manifold and engine
block. Start the Impala's engine and check for any leaks around the new intake
