Cold Weather Starting (Diesel Engine)
The following tips will help you get good starting in cold weather.
Use SAE IOW-30 oil when the outside temperature drops below freezing.
When the outside temperature drops below 0°F (-1
floc),
use your engine
coolant heater.
If you park your vehicle in a garage, you shouldn't need to use the coolant
heater until the garage temperature goes below 0°F (-I SOC), no matter how
cold it is outside.
To use the engine coolant heater, first turn off the engine. Then open the
hood, unwrap the electrical cord and plug
it
in. It uses normal house voltage
( I 10 volts), but:
A
CAUTION:
Plugging the cord into an ungrounded outlet could cause an
electrical shock. Also, the wrong kind of extension cord could
overheat and cause a fire. You could be seriously injured. Plug
the cord into a properly grounded three-prong 110-volt outlet.
If
the cord won't reach, use
a
heavy-duty three-prong extension
cord rated for
at
least 15 amps.
NOTICE:
After you've used the coolant heater, be sure to store the cord in
the manner it was, to help keep it away from moving engine
parts. If you don't, it could be torn and damaged.
