Description And Operation
EXHAUST SYSTEM
The basic exhaust system consists of an engine
Exhaust Manifold, turbocharger,exhaust down pipe,
exhaust pipe, exhaust heat shield(s), muffler and
exhaust tailpipe
The exhaust system uses a single muffler.
The exhaust system must be properly aligned to
prevent stress, leakage and body contact. If the sys-
tem contacts any body panel, it will transfer objec-
tionable noises originating from the engine to the
body.
When inspecting an exhaust system, critically
inspect for cracked or loose joints, stripped screw or
bolt threads, corrosion damage and worn, cracked or
broken hangers. Replace all components that are
badly corroded or damaged. DO NOT attempt to
repair.
When replacement is required, use original equip-
ment parts (or equivalent). This will assure proper
Alignment and provide acceptable exhaust noise lev-
els.
CAUTION: Avoid application of rust prevention
compounds or undercoating materials to exhaust
system floor pan exhaust heat shields. Light over-
spray near the edges is permitted. Application of
coating will result in excessive floor pan tempera-
tures and objectionable fumes.
EXHAUST HEAT SHIELDS
Exhaust heat shields are needed to protect both
the vehicle and the environment from the high tem-
peratures (Fig. 1).
DO NOT allow the engine to operate at fast idle for
extended periods (over 5 minutes). This condition
