EXHAUST MANIFOLDS

• Always compare the replacement unit to the original before installing your Exhaust Manifold.
• Always start with a cold engine. Removing Exhaust Manifold bolts from a hot engine may damage the cylinder head threads.
• Clean mounting surfaces are required for all exhaust manifolds. See the shop manual for any warnings or special instructions for the vehicle application.
• Use caution when replacing exhaust manifolds on aluminum heads.
• Never reuse the exhaust manifold gaskets.
• Torque all bolts to manufacturer’s specification. See the shop manual for torque specifications and sequences.
• If the original exhaust manifold is cracked and/or has a blue color, check for a rich running engine or an ignition system failure. If this condition is not corrected, repeat failure will occur.
• For ease of installation, replace the catalytic converter and manifold as an assembly on the 1996-98 Honda Civic, especially with high miles.
• Be sure to reuse all brackets and braces. Failure to do so will result in premature failure.
• Prior to installing the oxygen sensor into the replacement manifold, inspect the Oxygen sensor threads for damage. Failure to do so will result in damaged threads on the replacement unit.
• Be sure to use anti-seize on the oxygen sensor threads to prevent galling of the threads.
