MAINTENANCE AND SERVICING
The exhaust system requires no regular maintenance, but
it should be inspected periodically as follows:
1. Open the hood to its highest position. For instructions,
refer to
5.2.3 Opening Hood (Highest Position), page
307
.
2. Inspect the area around clamps (A) for breakage,
cracks, and rust-through. In addition to excess noise,
a leaky exhaust system may allow exhaust gases to
escape to the cab.
3. Check tubing for dents or crushed areas. Dents or
crushed portions of any tubing create exhaust
fl
ow
restriction and increase back pressure signi
fi
cantly.
Even relatively small dents will cause decreased fuel
economy and increased turbo wear.
If dents are
relatively large, increased bearing and cylinder wear
will occur due to increased exhaust temperature.
4. Make sure the exhaust system is secured to eliminate
vibration. The brackets (B) should
fi
t securely to the
muf
fl
er (C) and to the engine.
IMPORTANT:
Do
NOT
change muf
fl
er type, piping sizes, or
exhaust con
fi
guration. See your Dealer for proper
replacement parts.
