Moe, is your hemi the same generation or build as ours? what about the actual transmission, don't you have a 6 speed and we have an 8 speed? We have a Ram club up here and I have been asking around and the shutter thing doesnt appear to be an issue, open or removed, the air is the same pretty much, but there is a limit to how much air that AC Fan can move.

Also, outside air temp- mid-90s West said, that is what i am saying - mountains, up and down like where I travel. The physics of adding 50% more weight to the vehicle, and then going uphill, can now double, if not triple the load on the engine. There comes a point where the AC Fan air volume is eclipsed by the ability of the water to air cooling exchange. My point is flat areas, aside from stop and go, or on-ramps, most of the time the RPMS are 2K, but hill driving, has to have the average RPM 3K if not more.

But you said you tow 7800lbs? so that would be almost the same thing, so is there a difference in your setup than ours?

If you're towing in those temps,it's not the coolent temp that you should be worrying about,it's your oil temps.Your oil temp is going to go through the roof long before your coolent temps get dangerous. If I was you,i'd look into a thermostatically controlled engine oil cooler to.You can put all the fans you want on the rad,but your oil temps are still going to spike under load. FYI oil temps are more important then coolent temps.

Wild, do we not have an oil cooler on these trucks from the factory when you get the tow kit? The water cools the oil then right? or is it a Rad that cools the oil?

Crazy- the fans have multiple speeds, so that is thermostat controlled, but again there are 2 fans. I am 90% sure one is an AC fan and the other it thermostat. So I guess you can put a 2 position switch, but to me that's seems ghetto- if I am going to get all the right plugs and make harnesses, I am going to wire it just like it is in the Charger.

Anytime you bring 12V power into the cabin it's a fire risk, that is a big reason the number of 12V sources are limited now in most newer cars..... people wire up all kinds of **** to them, think they are electricians and then under a load, like it's raining or at night, your car catches fire as the wire you chose wasn't the right gauge. I have seen people try and use speaker wire for heated seats and for amps before, its crazy! You got a great idea for a race car or trail buggy, but mine is Gucci Girl truck :) No extra switches that aren't factory.

There's no engine oil cooler

Oh Good Lord Wild One, what have you done to me? This is going to be like a $200-300 upgrade just in case to make me sleep better and I didn't even know I shouldn't be sleeping not better! holy crap on a shingle!

what do you think of this combo.

https://www.etrailer.com/Engine-Oil-Coolers/Derale/D15451.html

High-Flow Engine Oil Cooler Thermostat, 185F FSM-185

Relocation Kit, Thermostat, Cooler. Going to need to upgrade those hoses- get some that come compressed and with the fittings on them- like these.....

http://www.ramforum.com/f44/remote_oil_filter_how--67947/index9.html

So this means more oil in the system, so thats a good thing, will stay cooler just for that reason too right? any risk on oil pressure going to low? or any other risks?

Side question- what does the Hellcat and SRT models do for an oil cooler? isn't there a MOPAR solution for this ? This isn't ghetto- not yet lol, but I sure would rather if it said MOPAR and don't you dare tell me to put a blue sticker on it!

See, I thought one like this was standard, hence, why I said the oil temp is a factor of the water temp, the cooler the water, the better it can cool the oil. But you are saying we don't even have one of these?

They have had these things for 30+ years! wth!

I'm not sure how much of an issue this is...oil cooling is usually handled by the "water" cooling, yet they add a transmission cooler for the tow package. Seems the engineers are more worried about trans temps. BITD, when cars were simpler, if you needed the engine to stay cooler, you put in a bigger radiator. The only times I used aftermarket oil coolers was on air-cooled engines.

You have to be careful, you can also over cool the engine, and that's not good either. You design and build for maximum load only if the vehicle is going to be at max load most of the time.

The crankcase is aways away from the water jackets for that theory to work ,and if that was the case the oil would be at the same temp as the coolent.I dare say you won't find many overhead valve V-8 engines where the oil and water are the same temp,the oil is always hotter.The crankshaft and bearings are well below the water jackets in most engines,and the only cooling they receive is via the oil in the crankcase,water jackets aren't anywhere close enough to provide any cooling to the oil feeding the bearings

RG you will have a slight pressure drop,but it won't be anywhere near enough to hurt anything. Cooling the oil will also help with it's viscotity and will keep your pressures more stable. I run 5W-30 with my relocated filter and it brought my hot idling pressures virtually back to where it ran with the stock filter and 5W-20.If you go for the double filter version it'll negate some of the pressure drop even with a cooler.Just try to keep the hose bends to a min,and run at least -10 (5/8") hoses and fittings.

Wahrsuul, I def follow that- hence the oil cooler thermostat. I am going to spend some time reviewing the temps as i drive - I won't be doing the oil cooler till next summer as now its not needed. I am going to move forward with the cooling fan now - call it and early Christmas gift!

This has def been a learning experience, thank you guys! hopefully I can report back a slam dunk solution for the fan system.

I follow that Wild- on the same page :)

Wouldn't call it a theory as it's the way pretty much all cars and trucks are set up currently. Still, you have a point - deep sump/aluminum finned pans were popular additions to performance engines.

The only concern I would have is during oil changes - making sure the oil thermostat is open so the cooler doesn't have a lot of old oil in it.

Check out the vehicles built for the police,the majority of them are equipped with engine oil coolers. Engine oil coolers have been around for a long time,they're not a new addition to the high performance world,they've been around as long as deep finned pans have been. You should always plumb them in after the filter so you're circulating clean oil through the cooler. They're no different then plumbing in a tranny cooler,when you do a tranny fluid oil change do you make sure the tranny thermostat is open,Rams have had tranny thermostats since 2013.

hey guys, roughly 75-78 degrees out, water is 204-205, oil is 212-215, 42lbs oil pressure at idle, up to 62 driving...... are these all normal? I am thinking we want oil lower right? I am due for an oil change, how much affect does that have?

Can I get some input guys are these temperatures normal compared to what you see? I am almost done with the wiring research on the fans, but i got sidetracked with this oil cooler stuff....

Just drove up into the mountains this weekend - water stayed around 195-200, oil was around 200 IIRC. I didn't keep checking once everything seemed stable.

Just installed my V6 E-Fan on my 2014 on the weekend. Was super easy and all plug & play.

I'll be posting up a HOW-TO YouTube video on the install this week once I edit all the footage. Will be nice to finally have some good info on this.

Oh and climate is SoCal so torture test will definitely be in this climate. I will say when it kicks in this fan moves a TON of air. Temp falls super quick when it kicks in, I don't think cooling with this fan will ever be an issue.

Just have to figure out the Hi/Lo speeds this fan has as the dan connection is a 3 pin but the truck side is only 2 pin.
