TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust efficiency of the Ford 5.8 liter V8 engine with E.F.I. (Electronic Fuel Injection). A performance gain can be expected by the installation of the system. This system requires no welding for installation and retains all O.E.M. emissions equipment.

Suggested Tools Needed for Installation: This vehicle has some metric fasteners.

❑ 3/8” ratchet socket set with extensions and a good assortment of S.A.E. and metric sockets ❑ Combination set of open-end wrenches, S.A.E. and metric ❑ Jackstands, screwdrivers, pliers, crescent wrench, etc. ❑ Liquid penetrant (GM #1052627), anti-seize compound (GM #5613695) or equivalent

SPECIAL NOTICE: This Edelbrock Tubular Exhaust System has received an Executive Order number (E.O.#) from the California Air Resources Board (C.A.R.B.) making it legal for street use in all 50 states. To assist you with emission equipment certification, we have included a silver fan shroud decal to help testing personnel verify the this part is a legal replacement on the vehicle for which it is cataloged. The adhesive-backed decal should be affixed next to the existing emission and engine specifications decal. Do not cover any part of your original emission decal.

WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty

on your Edelbrock Tubular

Exhaust Systems. Those products can cause excessive heat and moisture buildup resulting in corrosion and failure of the system.

NOTE: High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.

IMPORTANT NOTE:

Proper installation is the responsibility of the installer. Improper installation will void warranty and may result in

poor performance and engine or vehicle damage.

8. Unbolt and remove both exhaust manifolds.

9. Clean and inspect all sealing surfaces before assembly.

ASSEMBLY LEFT SIDE

1. With manifold port gasket in place, start a rear header bolt with lock and flat washer in place, leaving enough room for the manifold to slip into position.

2. Place TES manifold into position behind bolts with dipstick extending up between exhaust ports #3 and #4, then slide manifold into position behind rear bolt.

3. Start bolts #1, 2, 3, 4, and 7 (counting from front) using lock washers and a flat washer on the front bolt.

4. Re-attach dipstick bracket to sixth bolt hole back using 1-1/8" tube spacer and 3/8" x 2-1/4" bolt provided.
