Alliant power oil cooler

[Mharrison]

So I have contacted alliant power to show interest in having an aftermarket oil cooler produced for the eco diesel and I urge all of you too as well. Of we show enough interest and can prove there may be a market out there for this hopefully they will build one. They have a contact us section on their Web page or you can call them.

Great idea.

Ram really needs to get a hand on this, seems to be the worst problem they've had out of the EcoDiesel.

There are a couple people on the ecodiesel performance page including James that have put out a couple "feelers" trying to get the interest. It's a pretty hot topic and there are a couple ideas floating and I know of at least 1 real idea where th guy is going to completely delete the whole oil filter and cooler module and relocate the oil cooler to the front and oil filter somewhere else with an aftermarket filter head. At least we don't have the oil cooler in the same location like any of the powerjunks and I still think the powerjunk has a much highe oil coole failure rate than we do. Our problem is getting all the oil out of the system once it dows happen, but I've found flushing the water from the bottom up and out of the res bottle works great for me. But there's no way a dealer could legally do that.

Ya I among most would prefer to just see a quality cooler put in its place. But I have a good friend of mine who is a 6 liter powerstrokes specialist and those kits do really work

I think mopar was flawed in their factory oil cooler. It never should have been a coolant controlled heat sink. The benefit is it increases oil warm up time by using the coolant temp as well as friction. But it has an adverse effect on actual cooling because it is using too high of a temperature in contact with the heat sink to actually benefit.

The trick here would be to implement a thermostat housing and a front mounted air oil cooler. That way the factory heat sink would operate to raise oil temps to proper heat levels but at 205-210 the thermostat would open and allow flow through the cooler. So when the engine is under load it truly has an oil cooler. But only when it is exceeding the temperature threshold of the thermostat and coolant temp that implements the "ideal operating temp of the oil" as per VMI...

Though torque heavy I don't believe the engine was designed for a pickup. It is an efficient v6 with power sufficient for any full size vehicle, but it is not designed to be under load and really handle the heat. Though a hd truck size radiator was implemented for the diesel, everything else on the engine and transmission seems to be about heating the oil and transmission fluid rather than cooling it. Which is fine in day to day driving but again the adverse effects are shown under load...

I have heard nothing further on this issue...a friend of mines truck is in the shop now getting his second cooler done...completely out of oil this time motor got to about 280 degrees before he got to his shop where he could stop. The dealer is refusing to replace the engine and stating they only need to replace 1 head. Needless to say he is done with his truck and getting rid of it as soon as it gets out of the shop...first oil cooler went until 20k miles and the second cooler only lasted 10k. There's a problem that needs to be taken care of.

 

[jdn112011]

I'm getting awful close to 20k myself so we'll see the fate of my truck very soon. But thus far I've had no issues regarding my own oil cooler

 

[Mharrison]

I (knock on wood) have not had a single hiccup as of yet...and I will say my driving style as well as my daily commute 1.2 miles each way is not nice.to components like that so time will tell....

 

[jdn112011]

Haha my commute is almost exactly the same and in the north western plains of Minnesota my truck idles as much as Shawn's does warming up etc. And 1 mile commute by air driving is about the same as your ~1.2m

So I understand what you mean about driving styles not being nice to it. But I just use my block heater an extra lot and try to make sure my coolant temps are near 100F before I'm actually putting the truck under driving conditions.

So far it has been troublefree. And ~7-8k oil changes with the champion syngold

 

[Mharrison]

I normally allow it to warm up a couple minutes before I take off but our Temps aren't as bad as yours although when I take off coolant Temps are still only around 70 or 80. Have you noticed how high our oil pressures are when cold? Mine will idle around 30 psi and climb to 80+ getting underway. Seems like a crazy amount of oil pressure

 

[jdn112011]

80 during driving rpms isn't that high. All old gm trucks anywhere from I4's to v8's small blocks and big blocks see those oil pressures especially when cold. I guess I've never noticed near 80s on my truck but it could've been overlooked

 

[Mharrison]

Just seemed wild as I don't think my 07 gmc ever surpassed 60 psi

 

[jdn112011]

But I've seen early 90s 2.2L I-4 s10s with fresh rebuilds have damn near pegged oil needles all the time. A family member has a 98 3/4 ton 454 that still runs at 60 when it's at operating temp and driving normal. And I've seen the same on the 350s for many many other old Chevs.

I guess I'm not too familiar with the 2007+s too reference anything newer but I do get it's pretty high oil pressure for a synthetic oil on a new engine

I have read and re-read articles about oil and extreme temperatures in these posts. "Boost-in", is there any hope that FCA, will address the "antifreeze to oil warmer", issue and the extremes it allows and continues to create.
I have been posting my issues for about a year. The truck is competent as a tow vehicle on the highway as long as that highway is flat.
Unfortunately there are mountain ranges that cross this country in a bunch of regions. For me to visit any of my son's I have the Cascade passes, Rocky Mountain passes, and the Smokie Mountains Cumberland Gap with its downhill grade to get to Northern Virginia.
Other grades that present issues I have already expressed, Washington to SoCal. It is clear that "Temperatures" this current engines "Oil Heater" creates" as it exposes that oil to high '"Antifreeze" temperatures, coupled to the oil cooling to the turbocharger becomes excessive.
Where is FCA in fixing the issue?
I call this a design flaw!

Why is this up us us to solve? ? ?
