Default OEM Oil Cooler Kit and Installation DIY

Recently we had a customer ask us if he could do a write up of our OEM oil cooler kit and document the change in temps. This was down out in California. So here is his write up. Enjoy

Kit Link:

Summary​:

I went ahead and ordered the Never Ending Details oem oil cooler kit for my 2015 FRS. This
cooler is a oil to water cooler which utilizes engine coolant to cool the oil. The cooler is an oem
subaru unit utilized on several turbo cars like the wrx. I noticed my canyon driving temperatures
reaching 280 degrees F and thought a cooler would be a good idea. I also have a short
commute and was hoping the oil to water cooler would help with warming up the oil in the
morning. I have outlined my installation process below. I also took logs of oil temp, water temp,
and ambient temp for highway warmups and canyons runs before and after. I must add that this
is only the way that I installed the oil cooler and I in no way take any responsibility for any issues
anyone else has using this as a guide. I am just trying to help.

What you get:


The kit comes with the oil cooler, the extended oil cooler filter stem, two coolant lines, a
replacement oil filter, and some hose clamps (2 oem pinch style, 2 worm drive hose clamp
style). I went ahead and picked up two more standard stainless hose clamps at lowes as I prefer
those over the oem pinch style clamps.

Tools​:

Screwdrivers (flat head and phillips)
Pliers
24mm deep socket
Ratchet wrench
Oil filter removal Tool
Torque Wrench (Optional)

Installation​:

I have outlined and photographed the installation below. I have also put together a video
showing the stages of the process.

Video Link:

2 stock engine bay

Above you will see the stock configuration. The first step is to remove the intake tube from the
airbox, throttle body, sound generating tube, and breather hose. Use your pliers and
screwdrivers to loosen the clamps and remove the intake tube.

3 Intake tube removed

Under the throttle body you will notice a U shaped hose that loops coolant through the throttle
body. As I understand, the two fittings the hose loops between are utilized in forced induction
applications to cool a turbo. Since the frs/brz is naturally aspirated, they install a hose to loop
the coolant back into the system.

The next step is to remove the oil filter. Utilize your tool of choice to remove the filter. Once
removed you will see the stock short filter stem as pictured below.

5 oil filter removed

You are going to use your 24mm socket to remove that filter stem.

6 stock oil filter bolt removal

Here you can see the kit supplied longer stem which will pass through the oil cooler versus the
stock short stem.

7 bolt comparison

Next you will want to install one hose onto the straight fitting of the oil cooler and one hose onto
the bent fitting of the oil cooler. You will want to put the longer hose on the straight fitting. Go
ahead and install your hose clamps. Be sure to check your orientation to make sure the clamps
are oriented correctly. Then go ahead and install your oil cooler where the oil filter was prior, in
the orientation pictured below, with the bent fitting adjacent the ac compressor and the straight
fitting near the oil fill spout. The long stem passes through the oil cooler and threads in where
the short stem was before. No need to tighten just yet. The two lines are run under the ac
compressor to get to the throttle body. The line off the bent fitting goes directly under the
compressor. The line off the straight fitting loops around the front of the cooler and then back
under the ac compressor. I routed it between the two sensors on the block just below the cooler.
Be sure to keep the hose away from the accessory belt. You may want to route the lines before
installing the stem to give you the ability to move the oil cooler around.

8 pre installed lines and clocked oil cooler

In the photo below, you can see the hoses routed under the ac compressor and in position to be
hooked up to the nipples under the throttle body. You may need to trim their length depending
exactly on your routing. I trimmed them with a pair of dikes.

9 Lines run under ac compressor

Go ahead and remove that U hose under the throttle body and connect the hoses you ran under
the AC compressor to the now available fittings. In my case, only a bit of coolant leaked out, so
you may want to stuff some rags in there to soak it up. Take care to align your clamps so you
can access the worm drive to tighten them. These fittings are a bit smaller than those on the oil
cooler, so the hoses will not fit snugly unless you tighten the clamps down considerably. The fit
concerned me at first, but testing has showed no leaks so far.

10 lines run to throttle body

Now after all the lines are hooked up, you will want to go ahead and torque down the filter stem and oil cooler in the correct orientation. My research on Nasioc showed that 40 ft/lbs was appropriate.

Here is a photo of everything installed minus the intake tube.

Now go ahead and install your intake tube, be sure to attach it to the throttle body, airbox,
breather hose, and sound generator tube. Then go ahead and tighten down your clamps.

13 oil cooler installed intake tube installed

After the process is complete. I recommend running the car for around 30 seconds, revving the
engine a few times to 3,000 rpm. Then shut it off and check for any leaks, particularly oil leaks.
After that, you will want to fill and burp your coolant system. I recommend the grimmspeed
thread linked below and I also utilized a Lisle spill free system which is also linked below.
Finally, you will want to top off your oil if you do indeed swap oil filters as a bit of oil is trapped in
the old oil filter.

Logging:

Iíve attempted to document both oil warmup as well as oil temperature during spirited canyon
driving.

Oil Warmup Logging

Please see before cooler and after cooler logs below of the coolant and oil coming up to
temperature. Effectively identical procedures for each log. Start car cold in garage, begin
logging approximately 15 to 30 seconds after starting car. Pull out of garage after rpms drop
after cold start. Surface streets for approximately 90 seconds then highway driving at
approximately 70 mph until temperatures stabilize. As you can see, the initial warmup of oil
temperature does not seem to change much with the cooler, but the oil temperatures do
stabilize a bit lower with the cooler at freeway speeds than without.

Warmup without Cooler (oil temperature stabilized at 213 degrees)

highway no cooler

Warmup with Cooler (oil temperature stabilized at 204 degrees)

highway with cooler

Canyon Run Logging

This test was run at Palomar Mountain in Southern California. I have provided logs, before and
after cooler, of going up south grade which is a steep and tight uphill mountain road. It is the
most demanding road in my area for cooling purposes. While it is tough to get a totally clear run
up the hill on Sundays when I generally go, both runs were fairly clear. I got stuck behind a car
for a few corners on both runs until they let me by. I feel like they are pretty comparable. I do
believe I was driving a bit harder on the run with the cooler though as I got to know the road a
bit better. This is working the motor very hard, on and off redline in 2nd gear multiple times up
the hill.

Canyon without Cooler (max oil temp: 280.4, max coolant temp: 212)

palomar no cooler

Canyon with Cooler (max oil temp: 269.6, max coolant temp: 217.4)

Palomar with cooler

Conclusion

All in all I think it does its job. The cooler decreased my oil temperatures with minimal
expenditure and an easy installation.

Looks just like this but without the new hard pipe.

We did make up a kit that works and does need the hard line.

We have been selling these for a little over a year now. We shared our customers review to show what it can do for oil temps.

Or buy an OEM kit that works quite well for cheaper than most kits.
