Engine Oil cooler add?

[Cerberus]

So, the 2.7 in the F150 application has an oil cooler installed on the rear head, passenger side. There is a block off plate on the head where it would be on my 2.7.

Has anyone added an oil cooler? can it be done? Key consideration is space in that location for it to be installed.

I like the idea of being able to dump some of the oil heat generated by the turbos etc, to the coolant, especially since i moved about 1000 miles south..

Has anyone done this? Thought about it?

Is yours an ST? I thought they came stock with an oil cooler. Here's the ford one specific to the ST.

no sir, its a 2016 Sport. 

i followed the link and changed the vehicle to 2016 edge sport and it said it does not fit that application

I know this is an old thread, but it came up during a search.

Sounds like 15-18 Edge Sport is in the same boat as the 2017-2019 Fusion Sport. Ford didn't include the engine oil cooler with these 2.7L EcoBoost V6 engines.

The Edge ST has it, as do all the 3.0 EcoBoost V6 (MKZ, Continental, Explorer ST). I question the efficacy of this oil cooler because my 6F55 has a similar oil-to-water exchanger on the top of the transmission and Ford calls it a transmission fluid warmer.

The coolant basically helps warm up the oil faster on cold starts, and then tries to regulate it to the ECT which is about 200F-215F. So it's not really cooling the engine oil down, but in a towing application I could see it helping out.

You can retrofit the oil cooler - just need the right coolant hose that goes from the oil cooler to the degas bottle. On the Fusion Sport, a few people noted that the hose running from the heater core is not needed as its bend is just right to attach to the oil cooler.

Then again this is retrofitting the MKZ 3.0 oil cooler to the Fusion Sport 2.7L V6 - the Edge Sport/ST should be very similar but I'd double check the parts lists.

That's the transmission oil WARMER. I know it says Oil Cooler in the catalog, but in the Factory Service Manual that is the transmission oil warmer. Or more exact, an oil-to-water heat exchanger that basically warms up the ATF as quickly as the engine coolant warms up. The 6F55/8F57 works best with the Mercon LV trans oil hot, like 200F-220F, they tend to shift sluggishly or more conservatively when cold. Once the trans fluid is warmed up there's a valve that diverts it all to the oil-to-air exchanger/cooler.

As far as I know, the 2.7 in the cars and SUVs (Fusion/Continental/Edge/MKX/Nautilus) does not have the engine oil cooler that is next to the oil filter. Only the truck 2.7s (F-series, Bronco, Raptor) have that engine oil cooler. And all 3.0's have that engine oil cooler (MKZ, Continental, Explorer, Bronco, Ranger, etc).

My best guess? The car and SUVs don't have the engine/turbo load profile that need an engine oil cooler. The 3.0s are basically the same engine with more displacement but with bigger turbos, so the fact the cars get the engine oil cooler suggests something related to the engine. But on the trucks the 2.7 gets that oil cooler probably because they have to tow/haul extra cargo.

I have yet to find a quantitative difference in oil cooling performance. Only data I have is for the PTU cooler on the Taurus SHO/Interceptor where Ford claimed a 16% reduction in temperature. Since the PTU cooler is very similar in design to the 2.7/3.0 engine oil cooler, I'd surmise it is the same level of reduction. Assuming 220F-260F engine oil temps, that would help keep the oil at 200F-230F with the radiator/fan doing a lot of the heat rejection.
