NOTICE
The surge tank cap is a
pressure-type cap and must be
tightly installed to prevent
coolant loss and possible
engine damage from
overheating. Be sure the cap is
hand tightened and fully
seated.
The next time you use your
vehicle, recheck the level in the
coolant surge tank before starting
the engine.
The level should be at the proper
mark.

NOTICE
The intercooler system on the
6.2L V8 engine has a specific
coolant fill procedure. Failure to
follow this procedure may
result in the engine overheating
and in severe engine damage.
Turn off the ignition and let the
engine compartment cool down.
The intercooler coolant fill bottle is
located in the engine compart-
ment on the passenger side of the
vehicle.
Section 5
If coolant is visible but the coolant
level is not at or above the COLD
FILL (cold fill) mark, wait a while
for the engine to cool, then add a
50/50 mixture of clean, drinkable
water and DEX-COOL® coolant at
the coolant fill bottle. See "Engine
Coolant" in the "Service and
Maintenance" section.
If the engine is warm or hot, the
coolant level should be at or above
the COLD FILL (cold fill) line on
the side of the coolant fill bottle.
