• Working from under the vehicle, first remove the
exhaust H-Pipe by disconnecting at the exhaust
manifolds, muffler pipes and also be sure to
unplug all 4 oxygen sensors.
• Working from under the hood, disconnect the
emissions tubes from both exhaust manifolds,
then unbolt and remove the strut tower brace to
allow for clearance while lifting the engine on
the passenger side.
• Disconnect negative battery terminal.
• To facilitate installation of the header on the
passenger side, first remove the engine cross
member support bar (G-load brace), then
remove the motor mount nut on the passenger
side to allow the motor to be jacked about 3-4
inches.
• Working from under the vehicle, unbolt and
remove the starter and then the passenger side
exhaust manifold.
• Unbolt the steering shaft pinch bolt (located on
the driver’s side just above the steering rack at
the rubber coupler or rag joint). Pull the steering
shaft up off of the splines on the steering rack
and swing the shaft to the driver’s side of the
engine compartment. Unbolt and remove the
