No not my stang, my wifes LS1. She called me on my way home from work to say that she was inline at the bank and pulling out she noticed the temp was in the red and the check engine light was on. So she quickly crossed the street into a parking lot and shut it off. I got there and the fluid was alittle low. I put a half of a container in and drove home. I let it idle in the driveway and noticed something.

When I run the a/c the pass side fan kicks on. I assume this is normal. But once it starts to get hot I thought the drivers side is supposed to kick on. Her car has 2 fans, one for high and one for low right? There was no sign of any leakage and the car never started to smoke. I checked the oil and it was good and clean(did a oil change less than 50 miles ago). The temp passed 3/4 of the way and never did the drivers side fan kick on. What could this be? Thanks. -Mark
