are there any negative effects of leaving the rad. fan on constantly during driving? where as u just have a switch to turn it on when u turn the car on? i know a car with this but havent really asked specifics about it

 

ummm... to cool the water? duh?

 

If you have alot of electrical stuff (i.e. Big stereo and other toys) pulling power then yes, your alt will be doing overtime but, if all you have is a basic stereo and maybe some foglights then NOPE, will be fine, loud but fine.

 

I have my fans staying on all the time but I mainly track my car, so staying cool is important!

 

same here, I have a constant fan, ofcoarse a turbo LS motor in a 92 HB needs some air. Especially if you like I have a huge front mount in the front. If your using it for cooling purposes because your engine bay gets hot then do what i did. The only negative affect I know of is that it can less the life of the motor on the fan. My bros went out, SOLUTION. 50 bucks gets you a thinner more larger electric fan which is easy to install. He went to AUTOZONE for that.

hope this helps.
