I need a fan for a Reverse Rotation fan for my Suburban. The fan that came on it stock had 3 piddly blades so I dumped it for a flex fan. Stupid me forgot this is a reverse rotation waterpump setup. So now I need a good fan, clutch or flex, to go with my Reverse Rotation setup. Burb runs cool with the 180 thermostat and 40 degree weather but if you get stuck in traffic or idle too long temp starts climbing.
