Stopping The Diesel Engine - Dodge RAM PROMASTER 2018 Diesel Supplement

24 STARTING AND OPERATING

Stopping The Diesel Engine

Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially important
for turbocharged diesel engines.
NOTE: Refer to the following chart for proper engine
shutdown.

Do Not Operate The Engine With Low Oil Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as soon
as possible. A chime will sound when the light turns on.
NOTE: Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
