Overheating

I don’t live in Texas. I am military and moving from Alaska where I had no cooling problems to Alabama. The problem showed up in Texas when temperatures got in the 90’s for the first time. The auxiliary fan is working every time the air-conditioner comes on. I don’t have a fan clutch but my 3,300 cfm electric fan comes on at around 190F. It seems to show up on hot days at highway speed‘s or not at all.
Next will be flushing the radiator unless someone has a different solution I could try.

The problem with E-Fans for the engine = all depends on the CFM of the E-Fan and how the shroud is made. I’ve had experience with E-Fans before & honestly they aren’t all they’re cracked up to be. I had nearly a 500.00 setup on my H3 Alpha with a 5.3L V8 & it was “supposed” to be a performance upgrade (it did take the load off the engine), but better cooling than the OEM setup = it was not. I nearly fried a perfectly good V8 when on a trip just like you (on my way to my brothers wedding) temps went from the normal 195-215F range to 237F!!! I tried removing skid plates, pulling over & letting it cool down however it kept climbing. It only stopped & went down when I encountered some rain.
It was setup thru the OEM PCM to come on at 195F, but the shroud didn’t center the E-Fan and it had spots that didn’t let the air flow. Slapped on the OEM setup & I eventually found a fan blade that pulled more air. I wasn’t able to get my $$$ and I tossed the setup in the trash vs passing it onto someone else & have them overheat as well.
Funny thing was PCM of NC where I got the setup from changed the design a few months later......
On a D2 I have much more faith in a Hayden 2991 fan clutch & new Dorman 620-112 fan blade.

I’ve had this 3,300 cfm fan for seven years...2 in St. Louis (90’s), two in Turkey (100’s) and 3 in Alaska (80’s). Never had a problem. I used the top half of the OEM fan shroud and tucked the fan (comes with its own slightly smaller shroud) inside of that. This helps direct the airflow and keeps the upper radiator hose routing secure.
Not saying it couldn’t be the fan, but if it was it would be because it’s no longer performing like it used to.

How old is your fan? Could it be at the end of its life cycle? Connections are good?
