In very cold weather, it’s necessary to preheat the engine before
attempting to start it. Especially if the engine has cold-soaked at
temperatures below 25° F for more than two hours, use an engine pre-
heater to apply hot air directly to the oil sump, the oil cooler, the
external oil filter and oil lines, the cylinders and the air intake.
CAUTION
Starting an engine without proper preheat in cold weather can
cause damage from lack of lubrication due to congealed oil in
the system.
