sold on twins
My work truck(03 gmc 2500hd) was actually experiencing over heating issues 3 years ago while on a job where the only power was coming from the invertor in it. So the remedy our truck service company came up with was bigger altenator and the robbed the electric fans and shroud out of wrecked tahoe of the same year. Funny wired right into the harness. The tech had said most vehicles these days were never meant idle more than a half hour in hot temps. With that in mind the electric fans are a great idea for a lot of trucks mfg after 2000(rpms are lower). He also said that the dual fans act together in a 2 stage operation. But the most important point that calmed the boss down was this: incase one failed there was a back up. I know belts break too! Just food for thought.
