Active shutters, what's the consensus?

Marmay · Nov 20, 2021

Maybe only the 4x4 have them,but I am not sure.

Kursk, I am sorry for the missunderstanding. I thought we were talking about the Ram 1500 5.7 hemi the original poster has now.
I am unaware of every vehicle Chrysler engine and model ever made and it’s accessories and engine components. I am sure there are plenty of accessories and components I am unaware of.
If I was to restate the comment I made it would read: There is no oil cooler available from Chrysler for the RAM 1500 5.7 hemi and model for the years being discussed by the original poster as of now.
Thank you for allowing me to clarify my comment.
Additionally, I would ask you to look at the link you posted and review the application.
It reads: “Applications:392. Max AWD. Plus AWD. Night 4x4. Alpine 4x4. Yellow Jacket. Red Vapor 4x4. 100th Anniversary Edition”
I do not see 5.7 L any place on the link you have posted.

4 gen ram 1500 SSV police package trucks came with engine oil coolers. you can buy that engine oil cooler for all 5.7l, 4th gen, ram 1500 trucks. Or don't. Reality is reality whether you choose to believe it or not.

Kurek, the problem arises when the owner orders the part for his truck. When the owner provides his vin number for the parts department employee to order the part for his truck, no oil cooler will be listed.
Will the oil cooler you have listed on your second post work? It may very well will work. I do not disagree. However there is no oil cooler made for that engine or truck model the original poster owns.
Even if the owner orders the part, it will be unlikely the Chryler/ Ram dealer will install it for him. But, I guess it’s possible.
I have noticed in recent years, unless the part is ordered against a specific vin, the dealer is unlikely to install it.
I can only guess the reason might be recall issues or warranty issues. I am unsure, however.
Maybe you have some insight on this?
By the way Kurek, thanks for posting the SSV package. That package has some interesting specs.
Here‘s an interesting read I found about it.

Not every trim level had them, Tradesmans didn't typically come with the shutters for example.

You know now the that I think about it I never noticed shutters on my warlock. Good lol.

Just went and checked mine 20 Warlock. No shutters.

There are two issues at play. The average parts guy today can't find his own butt without the last 8 letters of the vin. The days of expert and highly proficient parts department staff are long gone. If they can't do a computer search they are hooped.

As far as dealerships installing, u have the same problem. The average mechanic can't install anything that they can't pull up a vin specific drawing and instructions for. Computerised training and install instructions is the only thing they know. You have to find guys that are used to modifying vehicles to get folks that are comfortable adding or substituting parts.

I have been following this thread and others like it for a while.
I have noticed the 5.7 hemi up until 2017 did not have an oil heater. 2017 and after does. Meaning the 2017 and after oil heater uses extremely hot water coming out of the forward part of the right head.
Even though it heats the oil, it also adds just a bit of cooling to the oil above a certain temperature. It can be seen on trucks 2016 vs 2017 that the oil runs a bit cooler. Sometimes people mistakenly thing it’s an oil cooler and it is not. It’s not made to cool oil, so it does a poor job at it.
A characteristic of engine oil is takes a while to transfer heat. Its molecular structure is much different than water, which transfers heat quickly.
The hemi’s engine block is cast iron. That means the property of cast iron, its also a very poor conductor of heat. Where aluminum is the opposite, it transfers heat quickly.
There is no hemi oil cooler available from Chrysler for the hemi.
So the hemi oil is continuously running warm Under many conditions.
No how does this relate to the AGS?
Because of the extremely poor oil cooling capability of the hemi, and the characteristics of poor heat transfer from cast iron blocks, removing the AGV brings engine coolant temperature lower to give the block and heads a better transfer of heat from the oil.
So to give you the readers digest condensed version, removing the AGV lowers the oil temperature via airflow and water coolant temperatures by heat exchange with the hotter oil.
So yes, for those people that tow a lot and get higher oil temperatures, it does indeed benefit the engine by removing AGVs.

This kind of explains why it STILL has a mechanical fan in 2021.

I am loving the grill shutters here in northern Canada. My ‘20 PW warms up twice as fast as my ‘09 1500 did. People can complain all they want about the new stuff, but when it works, it works well. Progress is not made by driving a model t.

You might want to go check to see if you even have them lol. Mine doesn't.

Nicholas Cove · Nov 20, 2021

For anybody that does not have shutters I'm curious; do you have a factory tow package? Mine has the tow package and no shutters.

kurek · Nov 20, 2021

Several retailers offer the parts, they won't stop you from ordering them and installing them. If you can change your oil filter and radiator hoses you can install the cooler kit.

I just did this on my Jeep Patriot that was not originally available with an oil cooler and the VIN didn't matter I just said I want these 3 parts please and when they showed up I installed them .

Sure there is, the police package had one from the factory.

I'd be curious to see how much heat that would pull out of the oil,as that's the oil heater/cooler module.How much heat would hot coolent actually pull out of the oil when it's at full oil flow and operating temp,as the oil flowing through it,isn't really in contact with much of a heat exchanger for any length of time.That's a pretty small aluminium heat exchanger to really accomplish much in the way of cooling the oil,it's tiny even in comparision to the heat exchanger on the side of the 8 speed,so how efficient it'd be as cooler is the question.Somebody with-out the oil heater/cooler needs to do a test on how much this would actually drop the oil temps.Not gonna be me though,as my dual remote filters keep the oil temps in my truck where i like them.

Colt4thHorseman · Nov 20, 2021

Kursk, how much did it drop you oil temperature?
did it prevent the oil from being warmed up quickly or was there a bypass in it?

I personally don't mind the AGS, for the most part my truck appears to be well cooled. Like you I tow a trailer and that's where the problems start, guys have reported temps well over 250, in the neighborhood of 275 at times and that is not acceptable.

I'm probably going to go with an external oil cooler, leave everything from the factory "as is" and then the cooler would be thermostat controlled and only activate when temps start running above 240 or so.

I don't believe removing the shutters will do anything useful. The truck controls the temperature very well (for the most part) and it does its thing to get the temps up to operating as soon as possible, and then keeps it at that point. Only when towing do the temps seem to run away for a bit but at that point the shutters are already open wide, fans are on, but the truck can't shed the heat any faster. So I don't see how removing shutters (which are already open and "removed" from the equation) are going to help fix that problem. If they were remaining closed due to a bug, sure that might help, but they're already open, removing them won't make the truck cool down any quicker; we're just building more heat the truck can shed so we need bigger coolers or more of them. Using a thermostat so that the new coolers only activate when the temps are running out of control means that we won't interfere with the heating/cooling system when we don't need it and the truck can operate as designed for 99% of the time.

If you are seeing 250-275 towing, you have some other problems that I would be looking into.

It's also an oil heater.The hose connections on it hook up to your heater hoses and it circulates coolant through the aluminium heat exchanger ,it doesn't circulate oil through the exchanger,just coolant.The oil only flows through the center port,that's the longer nipple you see sitting beside it,so the oil is not in contact with the exchanger for any length of time at full flow.

Dan Topp · Nov 20, 2021

Doing the headlights or in ram speak taking most of the front off.Don’t ask what a OE block heater takes on a 4x4

The Patriot unfortunately does not have a detailed display of engine oil temperature so I can't offer any kind of useful information on what the oil cooler did for me.
The "enhanced" tow package was not available on vehicles other than the Trail Rated model. Mine does not have the Trail Rated package.

The heat exchanger (still talking about the Jeep Patriot, I have not installed an aux cooler on my Ram) is dependent upon the flow of coolant through it for cooling and until the thermostat opens up there is no appreciable coolant movement. It is connected parallel to the radiator so the radiator does not directly deliver it with cold coolant at any time.

What prompted me to install the oil cooler was a comparison between the engine oil on my Ram and my Patriot at about the same mileage and it was visually apparent that the Patriot's oil had aged more in the same mileage. I do drive up mountains and sustain high engine RPM in that vehicle when going up hill on the highway so I'm sure head temperatures get fairly high. I figured if the manufacturer equipped the tow package vehicles with this cooler to help them tolerate extended operation at high RPM the same reasoning would apply to my use of the car.

Different Engines Same Oil

I have the good fortune of being able to own two vehicles and noticed I've put almost the same number of miles on them since the last oil change interval usi...

I'm not overly impressed by the factory oil cooler/heater on my wifes 6.4 Challenger,the oil temps still run consistently 20+ degrees hotter then the coolant temps do at 70 mph.

Andrew Austin · Nov 20, 2021

Yeah, mine has them. One of the first things the dealer showed me when I was first looking at the truck. I didn’t think they’d make any difference, but I was happily surprised.
