Notice: If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. See Recommended Fluids and
Lubricants on page 6-14 for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The engine coolant reservoir is located in the engine
compartment on the driver side of the vehicle. See
Engine Compartment Overview on page 5-14.
Check to see if coolant is visible in the surge tank.
If the coolant inside the surge tank is boiling, do not do
anything else until it cools down. If coolant is visible but
the coolant level is not at or above the FULL COLD
mark, add a 50/50 mixture of clean, drinkable water and
DEX-COOL
®
coolant at the coolant surge tank, but be
sure the cooling system is cool before this is done. See
Engine Coolant on page 5-31 for more information.
If the engine is warm or hot, the coolant level should be
at or above the FROID/FULL COLD line on the side
of the coolant surge tank. If the engine is cold, the
coolant level should be near the FROID/FULL COLD
line on the side of the coolant surge tank. If it is
not, there could be a leak in the cooling system.
