I used their generic bracket and made a few small modifications to it and tied it in to the driver's side motor mount by using the factory holes and replaced the 2 factory bolts that were not long enough with 2 grade 8 bolts.
The oil cooler was lightly dusted with black spray paints to make it invisible and there has been no change to engine temis engine temps after placing it in front of the radiator.
I had to purchase more hose hose so that I could reach from the filter to the oil cooler and back command back, so I bought higher quality rated hose to use throughout the entire system.
I also opted to go with the oil filter cap version of their kit to make installation incredibly easy incredibly easy since you just pop off your oil cap and install the new one with the older style oil filter from 2019 and 2020.

I follow, many thanks! I presume you're using a basic hydraulic heat exchanger (Hayden, etc.) sized appropriately for placement?

Apologies for some of that post not coming through correctly. I'm been doing a lot of driving this morning so I'm using speech to text for convenience.

@ZoneArc, so you installed the bypass filter, then plumbed in a cooler on the return line off the filter?

Is that a power steering cooler I see too?

Yes, installed bypass filter and then added a cooler.

Yes, power steering cooler to go in conjunction with my Hydro Assist + Apex Adjuster.
The Apex cooler won't work with the Evo Winch bumper since it chops the front frame and brings it in close for better approach angle, and so the cooler had to be relocated from where Apex usually puts it. Under the engine is a great spot for it since there's plenty of airflow and it's completely protected there.

Have you considered using Gates Power Grip heat shrink hose clamps? I straight up refuse to use worm drive clamps, personally. Been using the Gates Power Grip on everything from Dirtbike radiator hose to fuel lines. I think they perform perfectly, preserve your hose, look great and are cheap. The only drawback is they are a one and done. You put them on, and cut them if you have to take them off.

No, but I like that they look clean when installed.

The OP was talking about loss of performance. Its sounds tyical of high
exhaust gas temperature (EGT-temperature of the exhaust leaving the combustion chamber).The computer is dialing back power (pulling fuel) to lower the EGT. You cannot see the EGTs with the stock interface. High EGT can be seen underload like towing, long hills, etc.

Also charge temperature (hot air compresses less and makes less horsepower, ambient air mixed with hot air from the turbo and a saturated intercooler) directly effect performance. Only way around this is a bigger intercooler etc.

Ecodiesel has a stock liquid cooled oil cooler, I’m not sure how oil temperatures impact performance but it could effect longevity. Ecodiesels use synthetic; Conventional oil operating range is 250-300 F before it “burns” or loses its lubricating properties were synthetic is above ~450F.

In another thread, people towing up grades were hitting derates once oil temps crosses 265. That seems to trigger it every time and then it forces you to 40mph. I'm attempting to introduce additional oil cooling to keep it below 265.

As EGTs rises, the turbo gets hotter and the oil moving through the turbo picks up the heat. This is a side effect of the high EGTs also. Lowering your oil temps will not fix the high EGTs and stop the pulling of fuel if its really high EGTs. Thats all I'm saying.

I realize derating is a thing directly linked to engine tempatures built in to control tempatures but without a exhaust gas temperature (EGT) pyrometer you really do not know whats going on fully. High EGTs are one of the most dangerous things for a diesel engine.

Correct. With the Eco (and many diesels), forced induction creates an ideal environment where combustion can take place more efficiently. The piston crown takes-on a significant heat-load; "P" tubes, or directed oil "jets", spray pressurized engine oil in a continuous fashion underneath each piston, with the desired affect of capturing heat energy, localized on the opposite side of the forged aluminum piston, the oil then spilling into the sump, and then ultimately reconciling, or "giving away" heat to a cooler medium (engine coolant). This occurs at the oil cooler, co-located with the filter, as noted. This is why, in my estimation, polling the Eco's oil temp should be the on-screen while loading the powertrain, as oil temp responds most quickly to boost load, e.g. EGT sensitivity at the crown. Now, the tricky portion is to postulate "ok, oil is at 250f...EGT's "must be at or near 1375f", which, in my estimation, would prompt the operator to: reduce load via lower ground speed; shed ancillary systems that load the cooling package, e.g. HVAC; and/or reduce payload.

Hard to reduce EGT's by backing out of the throttle without becoming an unsafe nuisance on the road. If the oil temp is indeed what is causing the slowdown, we need to shed the heat from the oil. Driving 20mph in the hills is totally unacceptable. I'm just glad I don't travel much while towing when the temps are above 90°.

That's why you need to poll that temp, and monitor your speed/load.

Well, I started with an oil cooler. If this doesn't do enough, a large intercooler is next.
