I was sizing up some grill blocks on the Frontier and noticed there's a second fan on the front of the AC radiator. I realize now that this probably standard issue, but I was wondering how much air it would shove through the main coolant radiator. I know I could get by without the belt driven fan in the winter, but would I be able to wire this fan to a manual switch and run all year on just it? Obviously it wouldn't be able to cope with an engine idling for several minutes while stopped at stop lights repeatedly, but moderate pulse and glide should significantly reduce the sub 25mph operation where a fan is required anyway. Am I missing something? Should I not count on this fan for anything other than AC?
