Took the car for a short spin, the electric fan is not running, even when blasting the A/C but the engine is not overheating.
I also replaced both battery. Bough 2 big ones, but the top one doesn't fit. its doesnt go in, too long.
Whats the right battery size for the top one?
Here are the battery I got from Autozone: http://www.autozone.com/batteries-st...20339_910031_0
BCI Cold Cranking Amps (CCA): 950
Cranking Amps (CA): 1000
Here is a battery chart of the batteries you can use for the lower battery. For the upper battery, it is smaller in size. I believe you can use a 48/H6 or a 94R/H7 battery.
I guess I will replace the top one with a 48H6...
Auxiliary fan not turning on when A/C is turned on. Do I have to remove the front bumper in order to remove the fan?

I believe the fan would be the same across both 740s and 750s.
I would think that the fan would not be needed during winter. But I'm not sure. Lets wait for someone to chime in.
On the bright side, the engine is not overheating now.
