2. 2) LOW COOLANT LEVEL NOTE: If any ECT or Radiator Fan Control Module DTCs have set along with this DTC, diagnose them first before continuing. NOTE: If a Engine Coolant Temperature (ECT) DTC is set along with this code, diagnose the ECT DTC first. NOTE: Inspect the ECT terminals and related PCM terminals. Ensure the terminals are free from corrosion and damage. NOTE: The best way to diagnose this DTC is to allow the vehicle to sit overnight outside in order to have a completely cold soaked engine. WARNING: NEVER OPEN THE COOLING SYSTEM WHEN THE ENGINE IS HOT. THE SYSTEM IS UNDER PRESSURE. EXTREME BURNS OR SCALDING MAY RESULT. ALLOW THE ENGINE TO COOL BEFORE OPENING THE COOLING SYSTEM. Check the coolant system to make sure that the coolant is in good condition and at the proper level. Is the coolant level and condition OK? Yes Go To 3) . No Inspect the vehicle for a coolant leak and add the necessary amount of coolant. Perform «POWERTRAIN VERIFICATION TEST - VER 2»(ref-250650-S21741288272007031500000) .
3. 3) THERMOSTAT OPERATION NOTE: This test works best if performed on a cold engine (cold soak). Turn the ignition on. With the DRBIII(R), read the ENG COOLANT TEMP value. If the engine was allowed to sit overnight (cold soak), the temperature value should be a sensible value that is somewhere close to the ambient temperature. NOTE: If engine coolant temperature is above 82°C (180°F), allow the engine to cool until 65°C (150°F) is reached. Start the Engine. During engine warm-up, monitor the ENG COOLANT TEMP value. The temperature change should be a smooth transition from start up to normal operating temp 82°C (180°F). Also, monitor the actual coolant temperature with a thermometer. NOTE: As the engine warms up to operating temperature, the actual coolant temperature (thermometer reading) and the ENG COOLANT TEMP value in the DRB III(R) should stay relatively close to each other. Using the appropriate service information, determine the proper opening temperature of the thermostat. Did the thermostat open at the proper temperature? Yes Go To 4) . No Replace the thermostat. «(Refer to COOLING/ENGINE/ENGINE COOLANT THERMOSTAT - REMOVAL)»(ref-250623-S13260624812007031500000) .
