Diesel Fuel In Cold Weather
Unaltered diesel fuels thicken and gel in cold temperatures, unless treated. Virtually all
diesel fuels are climatized to allow their use in the particular region for that time of the year.
If it becomes necessary to further treat diesel fuel, it is the owner/operator’s responsibility
to add a commercial standard brand anti-gel diesel fuel additive, following that product’s
directions.
CE528
AntiFreeze/Coolant
CAUTION
Alcohol or Methanol base antifreeze or plain water are not recommended for use in
closed cooling section of cooling system at any time.
Because diesel engines are high compression engines and related higher engine operating
temperatures are created, the closed cooling system and engine, including related cooling
passages must remain as clean as possible to provide adequate engine cooling. This can
only be assured by using the proper antifreeze, water, additives and inhibitors. It is
recommended that the closed cooled section of the cooling system be filled with a low
silicate formula of ethylene glycol antifreeze in solution with deionized water. A low silicate
formula prevents antifreeze separation which causes a silicate gelatin to form. This gelatin
will block engine and heat exchanger passages causing engine overheating.
The coolant, if not premixed, should be mixed before being added to the closed cooling
system using a proper antifreeze together with deionized water. Common tap water or
softened water contains unwanted minerals which can leave large deposits in the system
that restrict the cooling system efficiency. In addition, additives and inhibitors introduced into
acceptable coolant solutions will form a protective film on internal passages and provide
protection against internal cooling system erosion.
