INSTALLATION INSTRUCTIONS
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.
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 accesses to the bottom exhaust manifold flanges.
Uselarge-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.
2. Spray WD-40 or some type of penetrating oil on all
accessible fasteners and fittings before attempting to
remove them.
3. From underneath the vehicle disconnect the Y-pipe from the
exhaust manifold.
4. Begin with the driver's side. Remove the manifold and studs
from the head.
5. Using a scraper, remove all carbon deposits and high spots
from head surface. At this time apply a high temperature
sealer to exhaust pipe flare in order to avoid problems
due to lack of space later in the installation.
6. Install header and be sure to tighten all the bolts between
30-35 pounds. For best seal, start with center bolts and
work your way out.
7. For '92-'95 models only begin on the passenger side by
removing the EGR tube to the exhaust manifold. Once the
bolts have been removed; slightly loosen the tube at the EGR
valve (located on the back of the intake manifold) DO NOT
REMOVE TUBE.
8. Now on passenger side begin by unbolting the four bolts and
nuts and remove the 2 studs from the head.
