Corrective Action
Add correct type of fuel. Try start-
ing the engine for 20 seconds and
then let the starter motor cool for
60 seconds. Repeat as necessary.
Cummins engine – plug the block
heater in eight hours before starting
the engine.

before starting the engine. Hold the
switch on until the engine starts.
Let engine cool. Do not restart the
engine until the cause of overheat-
ing has been corrected.
