Water pump, thermostat, or temperature sensor ... Timing belt/Water Pump Service (replacement of both) is a big issue, $750-$1200 if Seller does not have documentation, this is mandatory at stated mileage. What year is the NBC?

18613/P2181/008577 - Performance Malfunction in Cooling System

Possible Solutions

  • Check Engine Coolant Temperature Sender (G62)
  • Check Coolant Thermostat
  • Check Engine Cooling System
    • Put the key on, fan speed on 1, and push the a/c switch. Are both fans kicking on? If not, you found the problem.
    • Put the key on and fan speed on 1 with temperature set to hot. Does heat come out readily from the vents?
      • No. Probably the water pump is gone.
      • Yes. Probably the thermostat is gone.
Special Notes

  • Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
    • Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
    • Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
    • Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.
