Yes. Thinking Tilton was one of the “absolutely not”. The specs I’ve seen on them 160f continuous with 265f intermittent. The pump also says “diff cooler” right on it.

During a 30 minute track session. My diff temp will raise to 260 to 265 after 10 minutes and stay there with the diff cooler. Without it. Temps are close to 300. On the street, temps will raise to 250F after a half hour without the cooler on. Turn it on and the diff temps drop to 140F. I've had zero issues with the Tilton in 9 years. And it's pushing 85w250 gear lube.

Great.
Im not an expert, therefore I rely on what the Manufacturer says along with their Spec Sheets.
I replied on this thread about someone using a 12 volt pump to cool oil temperatures in a 3.0 Eco Diesel. I Researched this in depth, 3 plus years ago. Talking to several manufacturers. Via phone and email. Not one manufacturer recommended there product as an engine oil cooler pump.
Im only sharing information straight from the manufacturer.
I 100% believe what you are saying. I just don’t think a diff vs a 3.0 ED are comparable when discussing “oil cooling”.
I just looked at the Tilton website. No engine oil cooler listed. They do have a Diff/Trans cooler listed. The temperature specs are what I stated earlier. 165f continuous. 265f intermittent. 2 variations available, continuous and intermittent. There definition of intermittent was up to 2 hours. That is probably why the Tilton has never had a problem in 9 years. Based on your description.
I don’t think oil temperatures in an Eco Diesel can be kept under 200f. I have an extra 3 quarts of oil in my system (12 quarts). The extra 3 quarts are in the cooler loop. My oil temps stay between 210f and 240f 95% of the time. I can see lower on the long downhill grades (186f). The ED in factory form cannot be kept close to the Tilton 165f continuous Spec.
The only situation I’ve read about, approved by the manufacturer, is using it as a primer pump before engine start.
Anyway. Talk to the Manufacturer and read their spec sheet.
Tilton told me not to use their pump as an engine oil cooler. That is a good company doing the right thing over making a sell.

I have the continuous pump. That has been my experience with it. I track the temperature with a Speedhut diff temp gauge. The diff and cooler only take 4 liters of fluid.

Good luck in your search.

Been hot the last few weeks (seen 102) and the csf racing radiator with the lower temp thermostat has performed flawlessly. Oil temp has got up to 230ish climbing the sierras where coolant would hit 230 and oil would hit 250 last year. A quick fan on with the tazer drops it on the backside of a grade dramatically.

I am not looking into any further cooling. If anything a larger turbo would be my next goal. Reducing the discharge temp of the factory turbo into the intercooler would help everything stay cooler.

Snap shots of my conversation with Tilton, using their pump as an engine oil cooler. This was back in November 2022.


Hello,
I’m looking at your oil pump for an engine oil cooler.
I have a Gen 3 Mopar 3.0 EcoDiesel. I would tap the lines to and from directly to the oil pan.
The oil temp is always above 200*. I would turn on with switch at 230* off at 210*.
Would this be acceptable using your pump? I’ve read the install instructions, noting the temp range.

Hello Dean,
I would not use our pumps in that application. The heat will cause the pump to have a very short life span. I would look for a pump that is made from billet aluminum that can handle higher temperatures.

Tom

Well, that was a trip down memory lane. Just don’t think an engine oil pump rated for continuous load above 200f exists.
I’m not currently looking for one. What I did up doing is working (tapping into factory oil filter housing). I just wanted to share info.

I recently did camping trip pulling the off-road trailer. GCW is about 11k. 60 miles one way. 7500’ start elevation, hit 9200’, back to 7000’ then ending at 9200’ elevation. All mountain roads, lots of sharp curves. Avg. speed 35mph. This trip without the trailer before cooling modes I would average 245f.
With oil cooler fan On the entire trip pulling trailer, my max oil temp was 239f. Average was in the 220’s. Not a problem.

I think the real issue is Heat Soak. The ED has so much BTU’s that after long periods of driving everything under the hood becomes the same temperature as the engine itself. For example my wife followed me on this trip driving her 3.6 ‘JLUR. The engine oil temps are very similar to mine, however once at the campsite, I opened both hoods. It wasn’t safe to touch anything under my hood. Under the 3.6 hood, much cooler, you could actually touch engine stuff without fear of being burned.
I’m heavy, close to 7k. The trailer is about 4k.

Does anyone have any experience with aftermarket oil pans? I've e-mailed AFE and was told that they were working on ecodiesel stuff. They didn't say if it was just ram or the wrangler/gladiator was included... Nor did they have an ETA, but it's something maybe. I feel like with the added capacity it would help with the temp...

I was thinking the same thing back in ‘22. I talked to AFE back then. Same response working on it, no ETA.

I have an extra 3 quarts in my cooling loop. Bypass filter, Derale oil cooler with about 20’ of hose. If I don’t turn on the cooling fan, after long periods of driving, 2/3 hours the entire loop will match the same temperature as the engine. I monitor this with an added oil temp gauge installed in the oil pan. This temperature is lower than what stock was, but not by much. Driving conditions (RPM) also play a role.
