cooling

They make full size trucks now with Electric fans, if you have good ones, they work. Why would you want to go back to an engine driven fan to loose power to "fix" a problem that doesn't seem to exist in the first place? If the OP never hits 210 degrees under any circumstance, why worry? We don't know that yet.

The big trucks and motorhomes I've worked on and noticed,, that big elec fan is an auxillary fan,, and there's still a motor mounted fan on the inside.. My Motorhome also has both, with the electic seldom coming on except under long heavy loads, (N Cal mountains in summer, and that long (17mi) grade on I-15 into Vegas)..
