that steering wheel is in same orientation as prior to
disassembly.
8.
Form brake lines to clear T.E.S. pipes.
9.
Re-install spark plugs and reconnect wires left side.
10. Re-install temperature sensor wire support bracket and
reconnect wire to temperature sensor.
11. Re-install O2 sensor. Use anti-seize on threads of sensor and
torque to 30 ft./lbs. Re-route O2 sensor wire from wire loom to
O2 sensor (use O2 sensor extension lead supplied) making sure
all wires are clear of exhaust system.
•
ASSEMBLY RIGHT SIDE
1.
Remove fuel line bracket bolts on side and top of frame (two
bolts) right side.
2.
Pull lines away from frame approximately 1" and place any
spacer between lines and frame to hold away.
3.
Soak thermo wrap supplied in water, this will make it easy to

dipstick tube.
10. Install remaining bolts, lockwashers, dipstick and tube clamps
(see Figure 2) . Do not tighten bolts at this time.
11. Re-install O.E.M. front stud bolt with spacer (supplied). Align all
parts and tighten all right side bolts at this time.
12. Re-install spark plugs and reconnect wires.
13. Re-install diverter valve assembly in front O.E.M. stud bolt and
tighten.
14. Re-connect electrical connections and vacuum lines to diverter
valve assembly.
15. Remove A.I.R. Check valves from O.E. manifolds and re-install
them on T.E.S. Re-connect all injection hoses.
16. Raise vehicle and support with jackstands.
