5.8.8 Exhaust System
CAUTION
Engine exhaust stack may be hot. To avoid burns, do NOT touch exhaust canister when engine is running.
Allow sufficient cooling time after shut-down.
The exhaust system requires no regular maintenance, but it should be inspected periodically as follows:
Figure 5.107: Exhaust System
1. Open the hood to its highest position. For instructions,
refer to 5.2.3 Opening Hood (Highest Position), page
286.
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 flow
restriction and increase back pressure significantly.
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 fit securely to muffler
(C) and to the engine.
IMPORTANT:
Do NOT change muffler type, piping sizes, or exhaust
configuration. See your Dealer for proper
replacement parts.
