7.7 ENGINE EXHAUST SYSTEM
Rattles and noise vibrations in the exhaust system are
usually caused by misalignment or parts. When aligning
the system, leave all capscrews and nuts slightly loose
until all parts are properly aligned, then tighten all
fasteners working from the front of the system to the rear.
When replacing the muffler, also replace the tail pipe.
Before assembling components, use exhaust system
sealer at all slip joint connections.
When installing exhaust system components, allow
sufficient clearance between the components and other
pipes, hoses and wiring that could be adversely affected
by excessive heat.
