I have a 2012 Ram 1500 with a 180* therm and TYC E-fan, I live in Vegas and today it was 118*. My truck normaly runs at 185-187 with the fan running when the outside temp is above 110*. The wife and I went out today and she cranked the A/C to the setting right before max and my truck got up to 200*. Is this normal since the A/C was high and it's so hot outside?

Thank in advance for your help

I apologize that this is another E-fan question, but come on guys any help would be appreciated.

200 degrees on a 110 outside temp is damn good.

You may need to set the fan to 180* with the AC on, to see 185-187 again. I know with my DS inTune you have to set the fan both AC off AND AC on temps.

if you want it to cool down further, add some water wetter to the coolant.

Doesn't work. I've tied it just for an experiment. Switch to Evan's coolant for best results.

I've seen it work with my own two eyes. 3.4 whippled gt500 making 900+, watched the temps drop while it sat and idled after adding it.

You've mentioned Evans a couple times lately. Do YOU use it? I'm intrigued after doing some reading. How the hell is a person supposed to get ALL of the coolant out of their vehicle?? They claim their waterless coolant will work with up to 3% contamination of old coolant. 3% !?! How is one supposed to get all the coolant out of all the galleys, passageways, heater core etc?
If it was more straightforward of an install, I would. Maybe I'm missing something, but it seems only feasible if you're rebuilding an engine.

Yes I use it. In all 4 of my cars. To remove it you drain the system. Fill with their flushing agent or use distilled water(way cheaper). Drain system and make sure you empty out the overflow fill tank. We used a shop vac and also placed a rubber hose in the hole where t-stat sits since it was being changed and got the rest of it that way just experimenting but we also have an airlift tool that sucks air out completely in the system so you don't have any air left what so ever. It pulls a leftover coolant in the system also.

I don't know if the Hemi's have engine drain plugs but my viper does. We pulled the plugs after we did procedure above and there was very little coolant ,a few dribbles left over so I don't think it is needed.

Tried the water wetter in my Challenger and my Viper and it did nothing. Better off switching to this coolant and changing the T-Stat.

Coolant of today is highly corrosive and eats aluminum for lunch just sitting in your vehicle. Also your engine block. We have never replaced a heatercore, water pump or radiator in the last 20 years on cars that got switched over fairly soon and usually run them to 150,000 on up miles

From what to what? Numerous viper guys have tried it as well and say it did nothing. Maybe it likes Fords only. I had no luck with it what so ever in 2 vehicles.

May depend on the gauges too, if you're watching the factory one, some don't actually indicate subtle changes in temp, only a low, good, and high kind of thing.

It was years ago (2007 or 8 maybe?) But I recall the coolant being 205 210 or so at idle, dumped water wetter in the expansion tank and in the intercooler tank, temp went down into the 190 range.

Thank you everyone for your responses.

Got another one for you guys. How exactly is the E-fan supposed to operate?

Here's how mine works,

I have a 180* therm and a hemifever tune so when my temp get to 194* the fan kicks on. When it comes down to 183* it shuts off (usually settles at 185) . When my A/C is on at any setting (low or max a/c) it kicks on. Always at the same speed (heard there is a low and fast speed). When the A/C is on temps runner a little hotter 190-194, I'm assuming because of the A/C condenser.

So is this how everyones TYC E-fan operates?

Thanks again!

Sounds like how it's suppose to operate. And yes, when the A/C is running the fan is running by default.

Lower the fan temps in the tune to 189 except for the high MPH setting.
The computer has a ten degree split between on and off. I've experimented with lower temps and found that is what works best.
