So many problems starting up on my car...

Should the coolant fan be on when I start the ignition? When I press the accelerator, it roars too. I'm guessing that's not right? If that's not supposed to be, should I replace the coolant fan switch? Thanks.

 

bump.

 

Had the same thing on my car, switched out the fan sensor switch lower left of the radiator and the problem remained. Shortly after my A/C took a crap and then it wouldn't turn on. Planning on just bringing it in next spring.
