Hi,
Just installed a set of E fans, what is a good temp to have the low temp fan come on, and the high temp fan come on. For starters I set set the low one at 195 and the high one at 205. I have read where other folks have went a little higher. Also how hard would it be to add a temp. gauge that showed real temp. not just a needle.

Thanks for any input.

 

for a temp gauge that is the absolute easyest to install:

As for temps, what you have set should work great.

 

Or this one, it is a very nice product, just plug it in you're OBD2 port and it will do amazing things. http://www.scangauge.com/

 

I have a scan guage its real nice and its very accurate.

 

sounds like a pretty good toy .
about the scangauge ad does it actually help your horsepower or just compute the difference
thanks:santa:

 

Scangauge is nothing more than a scantool and a bunch of gauges all in one little unit.

 

I use 205* and 210* respectively. What did you set your temps with the first time??

 

This is what Troyer recommends. So keep it in the 200-210 degree range.

Gasoline engines generally make their absolute highest power output and get the best fuel mileage when the engine coolant temperature is in the 200-210 degree range. This is why your stock factory thermostat is generally a 192 degree unit, and why we recommend sticking with it in most cases. If you are doing any kind racing, or if you need to tow heavy loads in hot weather, etc., you can drop down to a 180 degree thermostat if you like & simply set the electric fan turn-on temperatures accordingly, thanks to the flexibility provided in this kit. We recommend that you DO NOT use any thermostat rated at lower than 180 degrees in these computer-controlled vehicles, or you will not get the best power or fuel economy, and might even experience driveability symptoms, MIL lights on the dash, loss of heater function in cold weather, etc.

 

Barry...just thought of a couple of things worthy for this thread last night. Not all the time, but a lot of the time, guys think you should have cars/trucks run as cool as they can! Not true. 200-210 is ideal and even upwards of 230 is nowhere near dangerous, so don't get caught up or drive yourself crazy trying to get that thing to run as cool as possible.

And also, I just remembered when I first got my fans and had my low temp fan set at any lower than 205, it seemed to run all the time...even like going down the road. Once it came on it stayed on. Does it hurt anything?? Maybe not...wear and tear on the fan maybe. Is there a need for the fan to be on all the time?? Nope. Remember your fan does nothing, it's completely useless above 35mph or so. With mine set at 205 it's never on going down the road (unless the A/C switch is on) and once I slow waaaay down or complete stop, it take a few minutes to kick on...perfect!!

 

I'm sure this might have been discussed to death in earlier posts, but...

Do you guys see any difference in acceleration or mpg?

Any hesitations of doing it again if you were to get another truck? Or would you rather spend the same money on a tuner if given the choice between the two?

Our AC in the current models seem to be weak. I assume you guys don't have any more cooling problems while running the efans?

thanks!

 

Acceleration and mpg increases noticed with e-fans, definetely. Not earth shattering, but noticed. That's a tough call on the fans over the tuner, have to say tuner would be worth it more. It does help the a/c quite a bit too. I never thaught the newer models had bad a/c? My dad's 07 seemed fine, but it was new and he only had it a short while, 6 months.

 

I have mine turn on at 215, so id say 205/215 for yours.
