EXHAUST SYSTEM
DESCRIPTION - 2.7L DIESEL
CAUTION: Avoid application of rust prevention com-
pounds or undercoating materials to exhaust sys-
tem floor pan exhaust heat shields. Light overspray
near the edges is permitted. Application of coating
will result in excessive floor pan temperatures and
objectionable fumes.
The diesel engine exhaust system consists of an
engine exhaust manifold, turbocharger, exhaust pipe,
resonator, extension pipe (if needed), muffler and
exhaust tailpipe (Fig. 1).
The exhaust system must be properly aligned and
secured to prevent stress, leakage and body contact.
The exhaust components should be kept a minimum
of 25.4 mm (1.0 in.) away from the body and frame.
If the system contacts any body panel, it may amplify
objectionable noises from the engine or body.
