NOTE: Installation of these headers requires an adequate workspace, general mechanic's tools general
mechanical "know how”. You should carefully read these instructions before attempting to install these
headers. This part is legal on Emission Controlled Vehicles.
1. Place vehicle in a location where the floor is solid and flat, with adequate lighting. Do not attempt to
work on a hot engine. Heat causes metal to expand and makes removal of fasteners difficult. Disconnect the
battery cables from the battery. Raise the front of the vehicle to obtain adequate access to the bottom exhaust
manifold flanges. Use large-base jack stands to support the vehicle. Do not rely on the jack! Block the tires
to prevent the vehicle from rolling off the jack stands. Use safety glasses.
2. Spray WD-40 on all accessible fasteners and fittings before attempting to remove them.
3. From underneath the vehicle disconnect the Y-pipe from the
exhaust manifolds.
4. To remove the driver's side manifold. First remove the starter. Remove the driver’s side manifold, studs
and heat shields from the engine, through the top.
5. Using a scraper, remove all carbon deposits and high spots from head surface. Apply a high temperature gasket
sealer to exhaust pipe flare in order to avoid problems due to lack of space later in the installation.
6. Recommended to remove steering shaft for easier installation of header. Note: Mark allignment of shaft.
Install driver’s side header using new head gasket + bolts. Use a high temp gasket sealer (O2 sensor safe) on
head gasket. Install header through the top of engine compartment. You might have to move hoses, wires
and steering shaft out of the way for easier installation. Starting from the center bolts in and working your
way out. Torque all fasteners to 30 to 35 pounds. Then, after installation of header is done, wrap steering
shaft with supplied heat-wrap and wire strips on vehicle. As shown in the picture.
7. Remove the air cleaner assembly. Remove the passenger side manifold. Then remove heat shield studs
and manifold from the engine through the top.
