i have not done this because my truck runs plenty cool, and there is no A/C. but yes, it will help. just keyword search cooling fans on JEGs and you will find what you are looking for.

i have an auxillery electric fan on the front of my rad. it is wired to a toggle switch,its not thermostate controlled. i just flip the switch when its needed. my truck has a very big cam,so it doesnt like extended idling in traffic on hot summer days. if it is getting to warm in traffc,it turn on the fan for a bit to cool the engine down. i used a 12 inch fan and its shroud i got from the auto wreckers. i still run the flex fan of the water pump as usual too.

Understand that a cooling fan on the front side of the radiator actually occupies space and can resitrict air flow.
If your engine driven fan is drawing enough air, the heat exhanger should be adequate enough to keep the engine cool.
You may consdier that you have a flow problem, and forcing more air through the radiator may not be the solution.
Cooling is all about surface area so the heat can be exchanged. If you have blocked fins, or passages that are not flowing then blowing around more air is not going to help with efficiency.
I run some fairly large engines, and I run them on the street. Trail temps when crawling a trail can get extreme, and I run a regular old fan and clutch. I keep higher compression engines really very cool and they have to idle for extended periods of time. Often this can be worse than traffic, because my speeds never reach more than a few miles per hour, so I dont have the advantage of driving speeds that force air past the radiator.

All new Engine , Radiator , 185 Thermostat , One owner truck it has allways ran hot . So what about no clutch and diff. mechanical fan ??

Lincoln Mark VIII 2 speed electric fan... insane amount of air! But you would need to upgrade to 3G.
