I didn't hear you say how much horsepower the alternators are using or the cost of parts. My diesel pusher runs hot but most of it is from dirt in the radiator. I wish I had your garage

Nice job, can you provide where each terminal goes, what degree of temp sensor did you use at the stat housing?

If you watch the other videos I posted on this I believe they'll answer all your questions. However regarding the temp sensor, keep in mind this is not a thermostatic switch control, it is a PWM variable control. I address this in other videos as well. It's controlled by an Arduino Uno and I used a standard Motorcraft coolant temperature sensor (which I believe is covered in my other videos as well). If you want to use a thermostatic switch to simply turn the fans on and off that will change the wiring setup entirely, as you'd use relays that would get turned on by the thermostatic switch instead of using the Arduino to be a variable speed fan controller.

great video. how are the electric fans working for you? I was hoping to do something like this on our 2000 Tiffin Zephyr with side mounted radiator and the Cummins ISM, after having two fan belts fail in less than a year. also, the last time it failed, the variable speed fan is coming on randomly and intermittently and its running hotter going up hills unless I turn on the dash AC which increases the fan speed. what do you think it is, the coolant temperature sensor? I don't want to run the AC all the time obviously. I just saw some of your other videos. youtube needs to bump you up on their algorithm. very educational!

I'm glad you're enjoying my videos! I need to do an update video on how the fans have done, so thanks for pinging me on it. I'll try to get it done in the next week or two. At this point we've done two trips, totaling around 5,000 miles. The system has worked great and the RV is way quieter, more fuel efficient, shifts smoother, more available horsepower, all good things. I have not been able to run the fans above 70% PWM because the controllers seem to overheat and shut off, which means I've been running at reduced capacity but still able to maintain temperature. Both trips I've done have been during cooler months so it hasn't been a full summer test. But since I've also been running at less than full capacity, I think it balances out. Overall, I've been very happy. Keep in mind that I also did a few things to reduce the load on my cooling system by divorcing the transmission cooling and then also adding external oil coolers, so that helps. I'm not worried about the upcoming summer months, but I do need to get the fans working at full capacity before then.

Hey Ted good work on the fans. How many miles on that coach ? I'm lookin at buying one of those HR's.

At this point I'm at something around 115k miles on mine. It's got its areas where it shows its age, but really it's doing pretty well for the miles I think. We bought it with 84k.

Nice Video - I also have a 2000 HR Endeavor. I am not as experience as you to install (4) fans. Would one or two be sufficient to boost the radiator cooling performance?

If your goal is to keep the mechanical fan and add some airflow, anything would help. However if you’re having cooling issues now I would suggest instead looking at separating out the transmission cooling circuit with dedicated coolers. I have another video on this project. The factory trans cooler uses engine coolant and so by separating it out you reduce the load on the system. Also, stock intercoolers and radiators are often clogged and worth checking. Mine were in awful shape.
