Maintenance
10 • 368
The exhaust brake system, used routinely at normal exhaust operating
temperatures, is virtually maintenance free. There are contributing causes
which can result in failures with the exhaust brake, including moisture, dirt,
carbon, and improper usage.
Starting the engine and idling for short periods of time is not recommend-
ed. Moisture is created within the engine and the exhaust system during cold
startups. When normal operating temperatures are not obtained, moisture
may get trapped in the valve housing resulting in rust and leading to insuffi-
cient operation of the exhaust brake.
To help prevent exhaust brake freeze-up, caused by periods of non-use, it
is recommended to use silicone spray at the points shown. Apply liberal
amounts of silicone spray to the moving joints whenever the motorhome is
parked for storage. Use a pair of pliers to manually operate the valve several
times to work the lubricant into moving parts.
NOTE: Do not use petroleum-based lubricants as these will burn
off and possibly create a fire hazard.
Some problems that may be encountered with the exhaust brake include,
but are not limited to, will not activate or deactivate, intermittent on/off oper-
ations or actuates with the switch off. These are commonly related to electri-
cal symptoms. Other problems such as slow operations, delays in operations,
and limited performance are mechanical symptoms. Refer these problems to
the dealer for diagnosis.
