PLEASE READ BEFORE PROCEEDING
Per Tronox© thanks you for choosing a Patriot Exhaust Product. To realize the
potential of Patriot’s engineering and excellent fit, Please Read and
Understand these instructions completely prior to starting the installation.
Check that you received all the parts listed on the parts list, if you have
any concerns, please contact PerTronix before continuing . Headers will have
the part number stamped in the flange.
Work Smart – Work Safe! Most Header and Exhaust Installation are best
performed on a lift. If a lift is not available, raise the vehicle and support
on quality Jack Stands on level ground. Do not rely on a jack!
Many factors affect he installation of exhaust headers, including worn or
aftermarket motor mounts, previous accident damage, aftermarket cylinder heads
that may have relocated port or spark plug locations, suspension and steering
changes, sagging of original unibody structures due to age.
Coating Notes: Coatings can be marred during installation if you are not
careful. If you are breaking in a new motor, the extreme heat can alter the
appearance of the coating and this is not a warranty issue. We recommend
breaking in new motors with stock manifolds or an old set of headers.
We use sealing beads on all our headers. The raised bead creates a better seal
virtually eliminating leaks if installed properly. It is important to install
all header bolts lightly snug and then tighten to factory torque specs
starting in the center and working outward.
Before starting, allow the vehicle to cool, disconnect the battery, and spray
a penetrating oil on all hardware and fittings that will need to be removed.
Once you remove your manifold, clean the sealing surface on the head of any
old gasket debris or carbon build up.

INSTALLATION
- Starting on the Driver’s side, slip the header into position from the bottom. If steering is straight ahead this gives best Pitman arm clearance.

IMPORTANT CHECK LIST

- If dipstick tube was removed , make sure it is installed properly and that the dipstick has been replaced.
- Double-check the tightness of all bolts including brackets and accessories.
START THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual noises or exhaust leaks. If everything is OK, stop the engine and tighten all bolts while the engine is still warm. NOTE: Check the bolts periodically to make sure they have not loosened.
