I do have some options for you but the radiator cooling fans are not typically the weak point in a towing setup. The factory clutch fan and or electric fans (if equipped) will be sufficient for most so long as you are towing within capacity. If you are having issues with the engine overheating then you most likely have other issues going on (i.e. stuck thermostat). With that being said, if you just want to upgrade to an electric fan setup then they don't really offer any exact fits for this but what you can do is measure the available space you have on the radiator and then choose the fan that best suits this space. For example, the Flex-a-lite 16" Trimline Reversible Electric Radiator Fan part # FLX116 measures 16" wide x 16-1/2" tall x 3-3/4" deep.

If you are trying to prep the vehicle for towing and don't currently have any overheating issues then your best option would be to add a transmission cooler and or oil cooler as these upgrades will be much more worthwhile for towing than the above. If you were to only do one, I would go with the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets part # D13504 with the Derale Snap-In Radiator Adapter Fitting part # D13035 as the transmission is most likely going to be your weakest link. Then if you can afford to do more then I would add the Derale Stacked-Plate Engine Oil Cooler Kit part # D15603 as this would be the next most beneficial upgrade for towing.
