Engine coolant temperature greater than 230 degrees F; MIL On; Engine shutdown; Diagnostic Scan Tool (DST) displays ECT temperature of 220 degrees F or greater; Engine coolant temperature gauge indicates 220 degrees F or greater; Malfunction Indicator Lamp (MIL) ON; Engine running too hot (overheating); Engine coolant temperature reading or estimate greater than 230 degrees F for greater than 10 seconds

Possible Causes

  • •Low coolant level
  • •Improper coolant type or incorrect 50/50 mix of coolant and water
  • •Loose or damaged fan belts
  • •Debris on the radiator core impeding airflow
  • •Hot air recirculating around the radiator
  • •Hot exhaust being drawn into the radiator airflow
  • •Cooling system malfunction
  • •ECT Circuit malfunction
  • •Cooling system is not full
  • •Improper coolant type
  • •Improper 50/50 mix of coolant and water
  • •Fan belts are loose or not intact
  • •Hot exhaust being drawn into the airflow through the radiator

Suggested Actions

  1. 1Thoroughly inspect the cooling system to find the root cause of overheating
  2. 2Verify the cooling system is full
  3. 3Verify proper coolant type and 50/50 water-coolant mixture
  4. 4Inspect fan belts to ensure they are intact and tight
  5. 5Clean the radiator core and remove debris (remove fan guards if necessary to inspect and clean the engine-side core)
  6. 6Check for hot air recirculation around the radiator or hot exhaust being drawn into the airflow
  7. 7Perform On-Board (OBD) System Check
  8. 8Connect Diagnostic Scan Tool (DST) in system data mode, warm engine to normal operating temperature, and run above 1200 rpm for at least 60 seconds
  9. 9Verify engine coolant temperature is over 220 degrees F with a temperature gauge
  10. 10Repair cooling system
  11. 11Verify ECT Circuit function by following diagnostic test procedure for DTC 217
  12. 12Verify and fill the cooling system to ensure it is full
  13. 13Ensure coolant is the proper type and mixed at a 50/50 ratio of coolant and water
  14. 14Inspect, tighten, or replace fan belts
  15. 15Inspect and clean the radiator core, removing fan guards if necessary to clear debris
  16. 16Check for and correct hot air recirculation or hot exhaust being drawn into the radiator airflow
