ENGINE COOLANT CHECK

Diesel Engine
See your engine operator's manual for information on checking and
adding engine coolant.
Fan Clutches
WARNING: Stay clear of the fan and fan area while the engine is
running or possible personal injury may occur.
Your vehicle's cooling system is equipped with a viscous fan clutch which:
• Helps control cooling, increases performance, improves fuel economy
and reduces noise.
• Is controlled by bimetallic spring sensors. Do not tamper with these
sensors as this may change their calibration or keep the fan clutch
from operating at all.
Gasoline Engine
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed in the Scheduled Maintenance chapter.
Note: Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The level may extend beyond the
MAX mark.
If the level is at the MIN mark, add coolant immediately. See Adding
engine coolant in this section.
