Coolant.. Thats the water radiator. Air can get caught in there and it will cause the car to heat up.

 

Ok, so pass. side fan does not spin or start spinning until I bump start it by hand. So going to dealer sat. to get it fixed, and hope that takes care of my ac issue... glad the driver side fan kickes on when needed to cool the engine still. that could have been bad in the fl heat/ traffic

 

Props for the input, and props to Infiniti of Tampa for a great/easy repair. Dropped car off, scored a loaner installed two new fan engines free- ac all fixed - again they were a pleasure to deal with today!
