Circuit/System Verification

1. If DTC P0480, P0481, P0691, P0692, P0693, or P0694 is set, diagnose that DTC first.

2. Observe the engine coolant level. The engine coolant level should be within the operating range. Refer to Capacities - Approximate Fluid,

and Engine Coolant in the Owner's Manual.

3. Ensure that the vehicle has the correct engine coolant with correct concentration and is not old, contaminated, or contains additives. Refer to

Recommended Fluids and Lubricants in the Owner's Manual.

4. Inspect the cooling system for the following:

* Leaks

* Kinked or pinched hoses, especially at the radiator

* Loose, missing, or damaged radiator air seals or deflectors

* Air flow obstructions or bent fins at the radiator or the A/C condenser-Refer to Symptoms - Engine Cooling (See: Engine, Cooling and

Exhaust/Cooling System/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Cooling).

Note: A small delay occurs before the ECM changes the cooling fan speed.

5. Command the cooling fans ON and OFF, low and high speed. The engine cooling fans should turn ON and OFF with each command.

瀚慖f the cooling fans do not function as indicated, refer to Cooling Fan Inoperative (LAU) (See: Engine, Cooling and Exhaust/Cooling

System/Testing and Inspection/Symptom Related Diagnostic Procedures/Cooling Fan Inoperative)Cooling Fan Inoperative (LF1) (See:

Engine, Cooling and Exhaust/Cooling System/Testing and Inspection/Symptom Related Diagnostic Procedures/Cooling Fan Inoperative).

Circuit/System Testing

1. Test the thermostat for correct operation. Refer to Thermostat Diagnosis (See: Engine, Cooling and Exhaust/Cooling System/Testing and

Inspection/Symptom Related Diagnostic Procedures/Thermostat Diagnosis).

2. Test the engine cooling system for overheating. Refer to Engine Overheating (See: Engine, Cooling and Exhaust/Cooling System/Testing

and Inspection/Symptom Related Diagnostic Procedures/Engine Overheating).

3. Inspect the water pump and coolant flow for correct operation. Refer to Water Pump Cleaning and Inspection (See: Engine, Cooling and

Exhaust/Engine/Service and Repair/Overhaul/100. Water Pump Cleaning and Inspection).

4. Inspect the engine mechanical for worn, leaking, cracked cylinder heads or engine block. Refer to Coolant in Engine Oil (See: Engine,

Cooling and Exhaust/Engine/Testing and Inspection/Symptom Related Diagnostic Procedures/Coolant in Engine Oil).
