DISASSEMBLY
1. Disconnect negative battery cable.
2. Raise vehicle and remove four O2 sensors, being
careful not to damage.
3. Cut left side exhaust pipe 1/2" from weld to allow
removal of cat. assembly
(See Fig. 1)
.
NOTE:
Before removing exhaust pipe/catalytic
converter assembly determine the position of cat.
inlet for re-installation. Either note measurements or
mark bottom of floorboard with chalk to show
catalytic location (Do not damage converters).
4. Unbolt and remove exhaust pipe/catalytic converter
assembly.
5. With catalytic assembly removed from vehicle, cut
right side exhaust pipe off from catalytic converter
approximately 1/2" ahead of weld
(See Fig. 1)
.
• RIGHT SIDE
1. Remove air inlet from intake manifold.
2. Remove spark plugs.
3. Remove manifold.
4. Install T.E.S. flange gasket and T.E.S. manifold from
top. Install header bolts supplied, and leave loose
enough to ensure proper alignment.
NOTE:
Use flat washers at slotted ends and lock
washers on all bolts.
5. Re-install dual catalytic forward assembly and use a
1" spacer (piece of wood, etc.) to provide the proper
clearance between the catalytic and the
crossmember.
6. Install right extension to catalytic (slip over the
catalytic nipple) and bolt onto right T.E.S. manifold
with donut gasket in place.
7. Tighten flange bolts. Be sure to locate donut gasket
with equal space all around for the best seal
(See Fig. 2).
NOTE:
Tack welding should not be done until the
entire system is securely bolted in place.
MIG
welding is desirable but gas welding can be used.
8. Re-install air inlet.
INSTALLATION INSTRUCTIONS
•
LEFT SIDE
1. Remove spark plugs.
2. Unbolt E.G.R. flange from manifold.
3. Remove exhaust manifold.
4. Install T.E.S. flange gasket and T.E.S. manifold from
top. Install header bolts supplied, and leave loose
enough to ensure proper alignment. Tighten all bolts
and nuts.
5. Re-attach E.G.R. tube.
NOTE:
Our T.E.S. E.G.R. fitting uses the stock
adapter.
6. Install left crossover pipe with donut gasket over
catalytic nipple and bolt onto T.E.S. Be sure to locate
donut gasket with equal space all around for the
best seal
(See Fig. 2).
7. With everything in place, tack weld T.E.S. to
catalytic.
NOTE:
MIG welding is desirable but gas welding can
be used.
8. After tack welding, remove assembly and complete
weld.
9. Re-install assembly and tighten all bolts.
10. Replace spark plugs and wires.
11. Check all wires and lines for adequate clearance.
•
FINAL INSPECTION
1. Check all lines (hydraulic, vacuum, air conditioning
and fuel) to ensure there is adequate clearance to
T.E.S. components.
2. Re-connect battery.
3. At this point it is a good idea to look everything over
and make sure that nothing was missed in
assembly.
4. Start vehicle and bring up to normal operating
temperature. Check for possible leaks.
5. Turn engine off and let cool. Tighten all bolts again.
