Gator1 Derale has patented this technology for use on it's radiator/oil cooler fans already.

It's also interesting to note that auto manufacturers actually plan the needed HP somewhat around the needs that it's alternator, pump, and cooling fans will place on it.

Gator1 Some interesting reading here. Our trucks already have a PWM feature to control the fuel injectors.

Pulse Width Modulated Alternators

steve05ram360 Yeah thinking of ways to control it so its not on 100% all the time. The programming language I use daily @ work is going to be made available for the community for free, with that comes plug ins that allow downloading to Arduino, beaglebone etc. Plenty of opportunity to control it with that. I could go program those with C but zzzzzz.......

Gator1 Maybe you could do something similar with an EWP so it doesn't run 100% as well?

steve05ram360 FWIW, my e-fans almost never come on... I have a push thru probe setup from hayden that ran $20 with an adjustable on setting. Works well and allows me to adjust if needed off road.

Gator1 After playing around with this technology I found on very cold days it's better to just start the truck and drive it, and get into the throttle ASAP to speed warm up times and the alarm will not go off.

Also after continuing to do research I have found that one of the reasons I'm getting better mileage is due to the PWM's "soft start" traditionally cooling fans are either 100% on or off, putting an immediate load on the alternator, and engine. With the PWM it slowly adjusts the speed of the fans or pump so there is less demand on the charging it only draws what it needs then either slows down or stops until it's needed again. This is something I never considered, but it does make some sense, and even more reason to go electric fans and pump with an PWM.

Pump was in slow mode. I was going down hill right out of my driveway. The display said coolant temp 99* looked at my other temp gauge, it said 100* I pulled over and as soon as it hit 102 it stopped beeping. So, I waited for it to warm up a little.

Gator1 OK this is a first. Went for a drive to the hardware store and out of nowhere I get this BEEEEEEP BEEEEEEEP BEEEEEEEP going off like the truck is going to explode. I look at the display on the PWM and everything is blinking as I'm trying to read what it says. "Low coolant Temp" lol OK apparently this has an alarm set if the coolant goes below 102*F it goes off! I already switched to my winter grill now it looks like I need to block some panels...It's nice to have a good radiator, there are worse problems to have!

It will work, but might make you
