Well, what do you think? But no, I did not notice this was in the V6 section so sue me. And no, I’ve only heard about the Hemi guys complaining about how hot their engines run but you know, now that you so kindly pointed out that this was the V6 section, I guess it is true the V6 guys are complaining about the same thing… Who knew.

A lot of people don’t seem to pay attention sometimes to particular sections so don’t act like I’m the first one to do it.
You're on here enough to know the sections,so don't try that excuse,lol.Glad you finally caught on,hopefully you'll pay more attention from now on. ;)

How long I’ve been here means nothing…and I can’t promise you if I’ll pay more attention or not. ;)

Drove my truck today for the first time since removing the shutters. In town the temp did get to 203 once, but otherwise ran 193-196 the rest of the time.

Before I would have been around 213-215 in town. The high extremes are what I'm trying to control by removing the shutters, the thermostat will take care of the low temps.

So far I am satisfied. I would like to know what the factory temp the fan comes on is, and maybe adjust it down some if necessary.

It may take a few minutes longer to get up to temp on cold mornings. However long it takes, it won't be near as long as my '94 Ram with the V-10, and the gigantic radiator it has.

That’s good that you got better results than I did when I tried it but maybe that’s just the difference between the bigger engine and the smaller engine because like I said, removing all but the top and bottom louvers on my mine didn’t cool it off very much.

As far as what temperature the electric fan comes on, I’ve been told that the condenser fan on these Hemi’s turns on at about 225° so that could be around the same for the smaller V6’s.

But yeah, even though it feels like my engine warms up quicker with the louvers in place, it’s probably not really enough to justify keeping them in just for that but then again, I have such a short commute every day to and from work that I’d like my engine to warm up as quick as possible with the least amount of idling.

But there is also the fact that my last truck didn’t have the shutters so who knows, I may just go ahead and take mine out again anyways just to take advantage of the cooler temperatures even though it really wasn’t that much.

Something else to consider, your cooling fan is electric so it’s only gonna turn on is when the temperature gets high enough or when the AC compressor kicks on whereas being that I have the mechanical fan, mine is always turning so who knows, that could be why the shutters in my case makes it feel like it does warm up a little faster in the winter.

Drove my shutterless truck almost 250 miles yesterday. Where I live is in the foothills, meaning, rolling hills with some pretty steep ones involved.

We drove up the mountains to western Va, with part of the trip on a pretty steep 2 lane road. The rest was mostly up and down interstate. Speeds of 75+ up and around 72 back, except for the two lane, where 35 - 45 was mostly the max.

On the steepest hill at lower speeds, I never saw above 205 deg water temp, and that was only for a few seconds before the temp started falling. Usual temp on the interstate was ranging 194 - 198, with the oil temp mostly keeping steady at 4 to 5 degrees lower than the water.

The engine still warms up quickly, not quite as quickly as before, but still quite fast.

I used manual mode, and changed gears as I saw fit. I just wish I could make the engine hold in gear longer before it downshifts. Shifts down way too early for my liking, even with very light throttle.

Fuel mileage on the meter was an even 24 when we got home. When I have hand calculated, the meter always shows abour 3/4 mile per gallon low, so I'm happy with that.

As for the shutters, I will never put them back. Steady water and oil temps without fast swings up and down is much better for the engine in my opinion. With steady climbs and falls, everything expands and contracts at the same rate.

Ram's objective is to make the EPA happy, and try to keep the engine alive past warranty, then you are on your own.

I know I never look at sections, just click new posts option hahaha.
I am guilty of replying and not looking at the section too.
I could maybe, somehow, possibly, OMG, the horror of it, the insanity, be guilty of this too.

That’s good that you got good results and as far as the engine still warming up quick, that really doesn’t surprise me being that your V6 doesn’t have a mechanical fan so that when you start your truck when cold, you can leave your shutters out because you don’t have a mechanical fan that still spins all the time even when not engaged, like I do. Maybe that’s why I could tell a difference on cold morning warmups.

I guess this is one of the downfalls to having a lifetime warranty because I’d love to be able to ditch my mechanical fan and condenser fan and get pretty much the same electric cooling fan you have because I could ditch my shutters and slap in a colder thermostat without making my truck take longer to warm up in the mornings when it’s cold.

But yeah, I don’t like that not only Ram but all manufacturers these days bend over backwards to appease the almighty EPA but it is what it is.

My shutters have been gone just over a year. My Temps are literally exactly as above. The most common coolant Temp. I see is 197*. Oil Temp. is almost always 4-5 degrees cooler at @ 192* - 193* With very few exceptions dependent on driving and Temp. conditions do they ever change.

Update and question.

Still liking the shutters out, even though it is getting colder in the mornings. It is taking a few minutes longer to get to operating temp in the 40 deg mornings, but I would expect that anyway, shutters or not.

My question is, will the dealer reprogram the fan to come on at lower temps? Last weekend was pretty hot.

I was creeping through a new housing track in the mountains with very steep hills. I saw temps of 230+ and never heard the fan come on. I am very happy still with the shutters gone, I am hoping I can get the electric fan matched to the thermostat temps.

Getting the factory fan to come on is pretty much impossible with the pulse width speed tech.

as a tech at a dealer, we cannot go into the pcm and change parameters for the cooling fan and the temperature it cycles at but if you have a diablosport tuner or similar you would be able to change fan operating temps that way

Thanks for the info. I was afraid that would be the answer. I will just put an adjustable thermostat pusher fan on the side of the radiator. That should take care of it.

The next thing is to figure how many CFM I want. Thinking somewhere between 2000 - 3000 CFM.

If you do the extra fan, part numbers and pics would be nice. I have the 850W OEM shroud fan which works ok, but temps do get up there.

I'll be sure to do that. Don't know how long before I do it. Sometimes I do those things right away, sometimes it will be several years down the road that I think to myself, "You know, I need to (insert project here).....

Removed the center 4 fins on my AGS right after I brought her home. I've seen temps as low as 185° on the highway but usually I'm running 195-199° even on the hot and sticky days here this past summer in NC.

I had mine run up close to 220 going up Lookout Mountain this past October. This was steep climbing at slow speeds. I turned the A/C fan on high and it must have kicked up the radiator fan to a higher speed (or I was at the engine temp that kicked it up) because the temp started going down right away.

Almost 1000 miles of a lot of hilly driving with that being the only time I saw any temps over 200.

I have a 2022 1500 Classic. They may have changed how the system behaves because I'm not having any difficulty with temps thus far.

During the summer, I was seeing 195-199 while the truck is in motion. If the truck idles or creeps in traffic, the temps climb fast but the shutters would be open so deletion wouldn't help in that scenario.

With the cold weather, I'm actually seeing a slight increase in temps; around 197-203 while the truck is in motion.

This was all during typical driving without the truck under stress.

For the record, I can't hear when the fan turns on and I've tried to listen. Not sure how you guys hear it. Also, I've noticed that the shutters are already closed in the cold mornings before I start the truck. I think on older trucks the shutters remain open when the truck is off?? Not sure about that.

Actually... I'm the one that started this post when I had a gen 4. I now have the 5th gen DT with Etorque and it stays cooler. I don't know if they reconfigured some of the cooling parameters or the MGU needs to stay cooler since it's water cooled and not air cooled like the Hemi or what... but the 5th gen seems to run cooler and I haven't even thought about removing fins. HunterCat, your Classic is running the same temps as my DT. I guess they made some changes for both.

I had to remove my shutters and at first I thought they would be something like our old model A JD but they definitely are not.I ordered the OEM block heater for winter.9792C3A4-0E09-46F5-8F79-63F25D5D47A7.jpeg
