I have a 97 dodge 2500 diesel truck and pull a 35 ft 5th wheel trailer. Truck runs cool until I hit grades the quickly heats up. I've changed the thermostate, but made no change in condition. Truck has air cond.condenser, and trans cooler mounted in front of radiator, and factory clutch fan. Should I remove factory fan and install an electric fan to cool the radiator ?? I'm told this is the best way to cool it at slow speeds

Forget the electric fans. There is no way that the electric fans can pull the air that your mechanical fan can and you DID NOT say that your problem is at low speeds, but high speeds under load. You are demanding more HP than your cooling system can handle.You have a fan clutch, is it good? That is the best start. Is the fan shroud in good shape?
Water Wetter is a joke. I do cooling tests on construction machinery. We tried this stuff on an 11 liter diesel engine with laboratory test conditions and equipment. It got hotter! Best mix for antifreeze per our testing is 30% but watch out for cold weather.
The above assumes that you have checked for blocked radiator inside and out. No bugs between the various coolers..Yes, they can build up there quickly!!
Good Luck

I had the same problem I added a elect fan as a pusher fan (outside rad blowing in ) an kept the factory set up the elec fan had a thermostat an would kick on at 180. It also made my ac temp blow cooler Killed 2 birds with 1 stone my fathers gm dulie had this set up right from the factory

I would chuck the factory setup and go with an aftermarket flex fan. They're a little louder but you'll notice a big differance at lower speeds. A flex fan is also cheaper than an electric one.

Yes this is a good idea. IT is really a problum that needs to be addressed by Dodge, but untill then replace the fan with an electric one that runs all the time the key is on.

Change to electric fan or try WaterWetter product and make sure your trans cooler is up to the load also---maybe put in a trans temp gauge or you'll fry the trans.

you could try manually seizing the clutch on the fan
