General Information

Engines in storage 30 days or longer require the following
procedures:
Maintain a "Full" fuel tank with the addition of diesel fuel
stabilizer to minimize microbial growth within the fuel
system. Run engine long enough to allow the fuel stabilizer
to enter the entire fuel system. If the engine is utilized in a
mobile application, drive vehicle to mix the stabilizer in the
fuel tank.
Before storage replace engine fuel filter(s) and drain all
water separators of any water.
Every 30 days or less, run engine until full operating
temperature has been maintained. For an engine with less
than 750 miles, run the engine to operating temperature
every time the engine is started. Run engine smoothly
through entire operating rpm range. If the High Exhaust
System Temperature (HEST) light is on, wait until it turns
off. If the Diesel Particulate Filter (DPF) light is on, do a
parked regeneration.
Before storage, change the engine oil and filter with
the appropriate engine oil for conditions the engine will
experience during storage.
Check and replace the air filter element and cover air
intake ducts to prevent moisture and debris intrusion during
storage.
Cover vertical exhaust stack.

an indicator eye, re-charge if below 12.6 volts. Check the
battery charge and recharge if needed. Remove batteries
and store in an area to protect from freezing if applicable. If
battery removal is not required (warm climate), maintain the
battery charge every 30 days.
Test the cooling system, additive levels and coolant freeze
protection. Coolant freeze protection must be set below the
coldest anticipated temperature during storage.
