Gus you can see I use the stock waterpump and fan and then I also have an electric fan as a pusher. But I only use the electric fan if stuck in traffic on real hot days to keep it below 200 if it creeps up over 200 when stuck in traffic for a while. I just have my fan on a toggle switch that I switch on when I need it. And it is ign control so in case I forget to turn it off it will go off when I turn the key off. Ron
