DISASSEMBLY - RIGHT SIDE
1. Disconnect negative cable from battery.
2. Use penetrating oil on all nuts and bolts to be
removed. This will prevent the possibility of broken
or stripped nuts and bolts.
3. Remove air cleaner system (note position of line and
hose connections).
4. Disconnect A.I.R. injection tube from exhaust
manifold and remove diverter valve (if applicable).
5. Disconnect spark plug wires, remove spark plugs,
and remove the first and second plug wire brackets.
6. Remove dipstick and both sections of dipstick tube.
7. Drain coolant (save for re-use, if desired), disconnect
temperature sensor wire, and remove temperature
sensor from head.
8. Remove bolts and exhaust manifold .
9. Remove knock detector wire and knock detector
from side of engine block.
10. Remove starter and starter shield. NOTE: Starter
shield may have to be modified prior to re-
installation on some applications (see Figure 1) .

DISASSEMBLY - LEFT SIDE
1. Remove air conditioning compressor support
bracket.
2. Disconnect A.I.R. (air injection reactor) tube from
exhaust manifold (if applicable).
3. Remove left nut holding A.I.R. crossover tube to rear
of engine and loosen nut on right side. This will
allow tube to be moved off left stud and up out of the
way (if applicable).
4. Remove shift rod pin at steering column arm and
move shift rod back against firewall. Note or mark
location of parts removed to facilitate re-assembly.
5. Disconnect spark plug wires and remove spark plugs
to avoid damage while installing TES.

DISASSEMBLY - CROSSOVER PIPE
1. Raise vehicle and support with jackstands.
2. Remove O2 sensor, being careful not to rupture or
destroy the unit.
WARNING: Do not clean this unit in any cleaning
solvent and do not rupture wire.
3. Making sure the converter (or muffler) is cool,
remove the exhaust crossover pipe. You may find it
helpful to clamp the converter (or muffler) to the
crossmember using pieces of wood and C-clamps.
This will allow you to "work" the crossover pipe
loose from the converter more easily. If the pipe is
frozen to the converter, it can be heated with a
propane torch (or equivalent) to help loosen the joint.

ASSEMBLY - RIGHT SIDE
NOTE: HEAT SHIELD MUST BE INSTALLED
BEFORE THE RIGHT SIDE MANIFOLD.
1. Position heat shield in frame so that it will protect
1-3/4"
fuel lines from excessive heat. Drill 1/4" hole into
the bottom of frame rail 3/8-inch in front of rubber
snubber on 4W.D. models and 1 inch from the
outside edge of frame. Drill another 1/4" hole 5
inches in front of the first hole, also 1 inch from the
outside of frame. Install heat shield using 1/4" nuts,
bolts, and washers supplied. On 2W.D. models slip
manifold into position and determine position fore
and aft where shield must be placed. Next, drill a
1/4" hole 1" from the outside edge of frame. Drill
another 1/4" hole 5" in front of the first hole also 1"
from outside of frame.
2. Install T.E.S. flange gasket and one 3/8"-16 x 1" bolt,
lock washer and flat washer at rearmost bolt hole
(leave bolt loose enough to accept T.E.S.).
3. Install dipstick tube and right side T.E.S. manifold
with dipstick protruding between A.I.R. log (if A.I.R.
equipped) and flange (original location).
4. Install remaining bolts and lock washers.
5. Align all parts and tighten all right side bolts at this
time.
6. Re-install starter and heat shield. Some models will
require that the starter heat shield be trimmed as
shown in Figure 1.
