| INSTALL TIME: Approximately 4 hours.
| DIFFICULTY: Average.
STEP 1
Disconnect the negative battery terminal and place the front of the vehicle
securely on jack stands.
STEP 2
Remove the hose clamp at the throttle body, unplug mass-air sensor, and remove
the 2 screws holding the top of the air box and sensor bracket from the front
of the strut tower then remove the entire assembly.
STEP 3
Remove the air-injection routing tubes by disconnecting the 2 vacuum lines at
the diverter valves, remove the hose clamps from the back of the air pump and
remove the 2 clamps connecting the hoses to the steel lines (near rear of
valve cover) and remove the entire assembly.
STEP 4
Remove all of the spark plugs and the dipstick tube. NOTE!!! On (94-95)
Mustangs the EGR tube on the passenger side exhaust manifold needs to be
removed before removal of the exhaust manifold.
STEP 5
Working from under the vehicle (use caution) remove the nuts connecting the
H-Pipe backward a few inches to gain clearance for the header installation.
STEP 6
Remove the stock headers and clean off any gasket material from the gasket
surface on the cylinder head. (The exhaust manifolds can be removed the inside
of the engine compartment).
STEP 7
Before re-installing, the dip stick will require clearance.
STEP 8
To avoid damage to the header coating or paint in
the engine compartment it may be necessary to raise the right side of the
engine while installing the passenger side BBK Header. The motor mount is
connected to the vehicle with 1 nut, easily accessible from under the front of
the vehicle.
STEP 9
Remove the nut and jack up the engine up using a floor jack or hoist being
sure to place the jack as not to damage or harm any part of the engine. Once
the engine is in the raised position place an appropriately sized block of
wood between the motor mount and the frame (this will hold the engine in an
upward position in the event of jack or hoist failure).
STEP 10
Set the BBK Header into place and start all the bolts by hand, then lower
the engine back into position in the frame, tighten the mount nut to a factory
specification. Torque all the header bolts to the Ford specification.
NOTE! Before tightening the engine mounts make sure the engine is sitting
evenly and both studs are all the way through the engine mounts leaving enough
clearance between the steering shaft and BBK Header to prevent rubbing and
vibrations.
STEP 11
Re-install the spark plugs and wires.
STEP 12
Before re-installation, the air injection tubes must be modified as shown
below using the hose and clamps provided in the kit.
IMPORTANT : All appropriate safety equipment and gear must be used during
the installation of this or any BBK Performance products or any time you work
on a vehicle.
BBK Performance accepts no responsibility for injuries or damage caused by or
during the installation of this product.
