Here are my issues
1. Call from daughter at 2:00 am on way home from Ski trip. Car is hot and we turned it off. BF says he thinks white streaks in the oil.

Here is what I found:
1. Oil ok, coolant full, engine runs fine.
2. CEL on and code is P0118 hi coolant temp.
3. Electic cooling fan is toast, screaming, stalling smoking.
4. CEL comes on everytime after clearing it.
5. Fan tries to run even when it sat overnight.
6. Temp. guage is at normal position even when sat overnight and cold 30 F.
7. Car was hard to start but ran fine afterwards. Suspect the computer is not happy with the overtemp code.

What I need to know:
1. Which sensor is thowing this code. The one at the thermostat or the one at the radiator.
2. Which sensor tells the fan to come on, becuase it is doing it even when it is ice cold.
3. Does there ever come a time with a 2:00 am phone call from your daughter does freak you out?


Thanks to anyone who can help or give me some ideas.
