• Use the best quality fuel of the
recommended grade.
•
Use recommended engine
lubricating oil.
• For manual transmissions and
auxiliary transmissions, leave the
transmission in neutral and allow
the transmission lubricating oil to
warm up (approximately 3-5
minutes) before operating vehicle.
Engine Block Heater (Option)
To preheat the engine before starting, plug
the optional engine block heater into a
properly grounded AC electrical source.
DO NOT start the engine with the heater
plugged in.
WARNING
Engine block heaters can cause fires
which may result in property damage,
personal injury, or death if not properly
maintained and operated. Regularly in-
spect the engine block heater wiring
and connector for damaged or frayed
wires. DO NOT use the heater if there
are any signs of problems. Contact
your authorized dealer or the manufac-
turer of the heater if you are in need of
repairs or information.
CAUTION
Always unplug heater before starting
the
engine. Damage to the cooling
system could occur if the heater is not
turned OFF (unplugged).
Depending on engine make, when the
temperature falls below -10°F (-24°C), the
block heater is required.
Engine W
arm Up
Engine warm-up allows oil film to be
established between pistons and liners,
shafts and bearings while your engine
gradually reaches operating temperature.
1. After you’ve started your engine,
idle it at approximately 600 rpm
while you check:
• Oil pressure
• Air pressure
• Alternator output
2. After a few minutes of idling at 600
rpm, increase your idle speed to
900 or 1,000 rpm. Continue your
warm-up. This procedure allows oil
to warm and flow freely while
pistons, liners, shafts, and bearings
expand slowly and evenly
. In
extremely cold temperatures, you
may have to increase idle speed.
NOTE
In colder climates where the tempera-
ture
is often below freezing, the warm-
up for turbocharged engines is espe-
cially important. Chilled external oil
lines leading to the turbocharger will
slow the oil flow until the oil warms, re-
ducing oil available for the bearings.
Watch the engine oil temperature or
pressure gauge for a warming trend
before increasing engine idle speed
(rpm).
3. Continue the engine warm-up until
the coolant temperature reaches at
least 130°F (54°C). At this
temperature, you can use partial
throttle. W
ait until the coolant
temperature is at least 160°F
(71°C) before operating at full
throttle.
