DIAGNOSIS AND TESTING
EXHAUST SYSTEM DIAGNOSIS CHART
CONDITION POSSIBLE CAUSES CORRECTION
EXCESSIVE
EXHAUST NOISE
(UNDER HOOD)1. Exhaust manifold cracked or broken. 1. Replace manifold.
2. Manifold to cylinder head leak. 2. Tighten manifold and/or replace gasket.
3. Exhaust Flex joint to manifold leak. 3. Tighten fasteners or replace gasket.
4. Exhaust flex joint. 4. Replace catalytic converter assembly.
5. Pipe and shell noise from front exhaust
pipe.5. Characteristic of single wall pipes.
EXCESSIVE
EXHAUST NOISE1. Leaks at pipe joints. 1. Tighten or replace clamps at leaking
joints.
2. Burned, blown, or rusted out exhaust
pipe or muffler.2. Replace muffler or exhaust pipes.
3. Restriction in muffler or tailpipe. 3. Remove restriction, if possible or replace
as necessary.
4. Catalytic converter material in muffler. 4. Replace muffler and converter assembly.

REMOVAL AND INSTALLATION
EXHAUST PIPE AND MUFFLER
REMOVAL
WARNING: THE NORMAL OPERATING TEMPERA-
TURE OF THE EXHAUST SYSTEM IS VERY HIGH.
THEREFORE, NEVER WORK AROUND OR ATTEMPT
TO SERVICE ANY PART OF THE EXHAUST SYSTEM
UNTIL IT IS COOLED. SPECIAL CARE SHOULD BE
TAKEN WHEN WORKING NEAR THE CATALYTIC
CONVERTER. THE TEMPERATURE OF THE CON-
VERTER RISES TO A HIGH LEVEL AFTER A SHORT
PERIOD OF ENGINE OPERATING TIME.
(1) Raise vehicle on hoist and apply penetrating oil
to band clamp fastener of component being removed.
NOTE: Do not use petroleum-based lubricants
when removing/installing muffler or exhaust pipe
isolators as it may compromise the life of the part.
A suitable substitute is a mixture of liquid dish
soap and water.
(2) Remove exhaust system ground strap.
(3) Loosen band clamp and remove support isola-
tors at muffler. Remove muffler from exhaust pipe
(Fig. 7).(4) Loosen band clamp at the catalytic converter to
intermediate pipe joint (Fig. 7)
(5) Remove intermediate pipe support isolator.
Separate at slip joint and remove intermediate pipe
(Fig. 7).
(6) Clean ends of pipes and muffler to assure mat-
ing of all parts. Discard broken or worn isolators,
rusted or overused clamps, supports, and attaching
parts.
NOTE: When replacement is required on any com-
ponent of the exhaust system, you must use origi-
nal equipment parts (or their equivalent).
INSTALLATION
When assembling exhaust systemdo nottighten
clamps until components are aligned and clearances
are checked.
(1) Assemble intermediate pipe to catalytic con-
verter and the isolator support to the underbody (Fig.
7).
(2) Install the muffler to intermediate pipe and the
isolator supports to the underbody.
(3) Working from the front of system; align each
component to maintain position and proper clearance
with underbody parts (Fig. 9). Tighten band clamps
to 47 N´m (35 ft. lbs.) (Fig. 8).
