hi,do the car start or do you have any starting problems ??

Customer: replied 2 years ago.
The car starts, no problem. When I turn the key to on, the fan runs even when cold.

this is most likely a problem with the coolant temp sensor reading hot al the time you should use a scan tool to monitor the temp reading of the coolant when the engine is cold if reading high replace the sensor let me know if you have any more questions
