PART 7: STARTING & OPERATING THE VEHICLE STOPPING THE ENGINE
(R10/06) Y53-6007 – 107 –
Stopping The Engine
Before Stopping The Engine
A hot engine stores a great amount of heat. And it doesn’t
cool down immediately after you shut it off. Always cool
your engine down before shutting it off. You will greatly
increase its service life.
Idle the engine at 1000 RPM for five minutes. Then low
idle for thirty seconds before shutdown. This will allow cir
-
culating coolant and lubricating oil to carry away heat from
the cylinder head, valves, pistons, cylinder liners, turbo
-
charger, and bearings. This way you can prevent serious
engine damage that may result from uneven cooling.
Turbochargers
This cooling-down practice is especially important on a
turbocharged engine. The turbocharger contains bearings
and seals that are subjected to hot exhaust gases. While
the engine is operating, heat is carried away by circulating
oil. If you stop the engine suddenly after a hard run, the
temperature of the turbocharger could rise as much as
100°F (55°C) above the temperature reached during oper
-
ation. A sudden rise in temperature like this could cause
the bearings to seize or the oil seals to loosen.
Refuel Before the Final Stop
Air space in your fuel tanks allows water to condense
there. To prevent this condensation while you are stopped,
fill your tanks to 95% of capacity.
WARNING! Do not carry additional fuel con-
tainers in your vehicle. Fuel containers, either
full or empty, may leak, explode, and cause or
feed a fire. Do not carry extra fuel containers,
even empty ones are dangerous.
• Diesel fuel in the presence of an ignition
source (such as a cigarette) could cause an
explosion. You could be seriously injured. A
mixture of gasoline or alcohol with diesel
fuel increases this risk of explosion.
• Do not remove a fuel tank cap near an open
flame.
• Use only the fuel and/or additives recom-
mended for your engine.
