If you go with a good fan, it won't be a problem.

I could not be happier with my Flex Lite 180. It works great!

The only modification I had to make so it would fit my 89 22RE was 2 half circle cut outs on the bottom to clear the lower radiator hose and drain petcock.

Summit Racing will beat any price you can find in the Net.

This place has them for $276 http://flexalite.carshopinc.com/product_info.php/products_id/71712/180

Over heating has NEVER been a problem. If anything, my trucks temp is a lot more consistant, whats more, it warms up a lot faster on freezing mornings. I let the truck idle a couple minutes in the morning with the A/C on to melt the ice, scrap what ice is left on the windows and within a half mile of driving, the engine temp is up to normal.

I will never switch back. I have gained more power, better gas milage, faster warmups, less wear and tear on the engine and more consistant operating temperature.

Take care.
