First of all, you need to figure out what type of coolant is in the engine now. Most likely it is the Ford Gold stuff. Best way to figure out would be to go under the radiator and fill a plastic cup up with what's in the radiator. If it appears clear to a gold tint you most likely are running the gold stuff. Many folks have elected to swap out and use ELC coolant, but to do that means a complete flush of your coolant system. It's not hard, but it must be thorough.
Since you don't know much about the engine in your truck, there are a number of things you should consider. EGR Cooler can be a problem which generally is affected by the Oil Cooler. If the Oil Cooler gets stop up it will likely result in failure of the EGR Cooler which in turn results in Flash Boiling of the coolant, and eventually failure of the headgaskets. To counter this, a number of us folks have elected to delete the EGR Cooler and either clean and restore the current Oil Cooler or purchase a new one. The key then is to ensure your coolant system is properly maintain i.e. clean of any crud that would be counterproductive to the Oil Cooler.
(This will bypass the egr electronically right?) You only bypass the error code regarding EGR. You must remove the EGR Cooler and EGR valve then the Tuner will bypass the error code.
After that, a Coolant filtering system would be a good investment to help maintain a clean system.
The truth is: There is a lot you can do to keep it running right. It just depends on how you are going to drive it and what do you want it to do...
