10. Replace water temperature wire.
11. Replace spark plugs and wires.
12. Re-install A.I.R. fittings (use A.I.R. adapter fitting in kit,
if necessary).
Extension Pipe
1. Cut O.E.M. exhaust pipe approximately 1/2” to 3/4” in
front of the catalytic.
2. Bolt catalytic back into vehicle with front in original
location.
3. Install T.E.S. pipe over catalytic inlet and bolt to T.E.S.
manifold using donut gaskets provided.
4. With everything in place, tack weld T.E.S. to catalytic.
Note: Tig welding is desirable but gas welding can be
used.
5. After tack welding, remove assembly and complete
weld.
6. Re-install assembly and tighten all bolts.
7. Check all wires and lines for adequate clearance.
FINAL INSPECTION
1. Check all hydraulic, vacuum, and fuel lines 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 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.
12. Re-install spark plugs and wires.
Note: Alternator and dipstick tube must be removed
for future spark plug changes.
13. Re-install alternator and A.I.R. fitting. Use A.I.R.
adapter fitting and kit, if necessary.
14. Re-install dipstick tube.
15. Take wire pack (wrapped with aluminum tape) out of
plastic clip on crossmember and re-position toward
front of vehicle for additional protection from heat.
Use tie wrap (in kit) to secure.
