With the engine off and temperature cool:
WARNING! Do not remove the radiator cap on a hot engine. It
can cause scalding coolant to spray out and you could be
burned. If the engine has been operated within the last 30 min-
utes, be very careful in removing the radiator cap.
1. Inspect coolant level.
2. Inspect fan belts and condition of coolant hoses.
3. Inspect for coolant leaks at the following locations with the engine run-
ning.
WARNING! Do not work on 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.
a.Heater and radiator hoses.
b.Radiator tanks and core.
c.Water pump input shaft (at pulley).
With the engine off and temperature cool:
1. Check and adjust fan belt tension.
2. Check antifreeze concentration and
coolant level.
3. Recharge coolant conditioner, if nec-
essary.
4. Inspect coolant hoses and hose
clamps for tightness.
5. Check for secure radiator supports
and brackets.
6. Clean debris from heat exchanger
core fins — radiator/Charge-Air-Cool-
er/condenser cores.
Clean Cooling System.
1. Inspect and re-
place “spongy” or
deteriorated cool-
ant hoses.
2. Inspect and re-
place worn or de-
teriorated fan
belts.
NOTE: If Long Life Coolant (LLC) antifreeze is used, recharge at 150,000 miles/241,000 km; replace at 300,000 miles/483,000 km.
•Be sure different types of coolant are not mixed. Stay with the same coolant until a complete Replacement is performed.
