So I just purchased and installed a 16 inch summit e fan on my 5.2l durango.
I have it powered by the accessory 20 amp fuse in the fuse box the the durango, It supposedly draws 13.6 amps so that isn't a problem.
It is rated for 2100 cfm which, from what I have heard on this and other forums, is plenty enough for a 95* F environment.
Once it gets heated up it generally runs at 200* at 60mph, about 215 at 45mph, and about 230 when idling (I collected these numbers when it was 94 degrees F). I have come to the realization that I really don't know what is a dangerous operating temp or not. Back in the olden days with the clutch fan, It was below 210 as long as you were moving. However in 100 degree temps if you stopped moving, It would quickly get up towards 220.
Anyways, today I went to visit my girlfriend at work. While I was driving through the parking lot It was at about 210. I stopped and parked, and just for the sake of testing put it on full blast A/C and let it idle for a few minutes. It quickly got up to 210 and then 220. At 220 I turned the A/C off, let it sit till It got to 210 and then turned off the motor and walked inside. I forgot my cell phone in the truck and immediately turned around to get it. Stick my key in to check the temp, and it was at 250! First thing I thought was a lack of water, there wasn't much in the reserve water tank. I popped the cap off the radiator and there was definitely water (and a lot of pressure) in there (thank god I was smart and used a towel to open it.
Now I'm pretty sure I'm running about a 30/70 ratio of antifreeze/purified water. I suppose the simplest solution would be to put in some actual coolant (ive heard royal purple liquid ice works well). But my real question is: will that be enough, and do you guys think that there is some other problem with the coolant system? I know trucks generally heat up 20 degrees when you turn em off, but 250 is a scary number.
But that Is a temporary solution at best, I need to get a larger fan, or 2 smaller ones. The CFM on this fan is supposedly ok for what I am running, but its tiny, and is probably only capable of cooling 60% of the radiator at best (as that is how much of the space it takes up).
