Found some unversel 18, 16 and 14 inch electric fans at advance auto. i was thinking about putting on my truck instead of my clutch type fan. what size fan i should get and how many to make my truck run even cooler? 2 -12inch fans 1- 18inch fan any recomandations?

 

For what it's worth, it was recommended to me at a minimum two 14 inch fans, but two 16s will fit no problem and that one 14 was enough if I didn't plan on using my A/C much.
