46 Maintenance and Service
DO NOT use antifreeze formulated for automobile gasoline engines. These
have a very high silicate content that will clog the radiator and leave unwanted
deposits in the engine.
A well functioning and maintained cooling system is as important to the
engine as performing regular oil changes or using good fuel. To get the best
result use quality products and service the system at the correct intervals.
Please read this section carefully.
Keep the radiator (including charge air cooler) and the frontal area free from
bugs, dirt, leaves, etc. (see “Cleaning Charge Air Cooler and Radiator
Package” on page 68 for cleaning information).
Check the coolant level in the tank regularly. Fill the tank as necessary with
the correct coolant.
Inspection of the whole cooling system is important. Check for swollen or
deteriorated heater and radiator hoses, loose hose clamps and connections, and
radiator leaks.
DO NOT work near the fan with the engine running. The engine fan can
engage at any time without warning. Anyone near the fan when it turns on
could be seriously injured. Before turning on the ignition, be sure that no
one is near the fan.
