Most likely it's aluminum

You mean you can't find "thermostatic" on the periodic table? I wonder why?

Oh duh. That's right. The whole radiator fluid thing is the temperature control. I was so enamored with the setup, I was thinking off the top of my head.

Its not a problem though, you can very easily just run an inline thermostat like this

A hybrid system would be interesting. Keep the fluid cooler and have the air cooler on a thermostat. That way you get the best of both.

I ran the oem forester cooler in tandem with a mocal thermo sandwich plate to oil cooler w/ fans. Worked great for getting temps up quickly and then keeping them down once they got up.

This thread has inspired me to run a front mounted oil-to-air exchanger in parallel with my JSRC dual oil cooler radiator if/when I go FI.

In your planning for FI, research positioning of the ducting, mounting of the charger, and where you oil cooler lines will run. I'd guess the thermostat needs to be reasonably close to the engine to operate correctly.

I want to assume that my current 2017+ Jackson Racing sandwich plate is thermostatic, unless I'm reading their product page wrong. If not I'd just swap it out for the greddy plate like grumpysnapper is using.

Do have the dual radiator or just an oil cooler?


Another question: Will the FA20 oil pump provide enough volume and pressure to support the additional cooler?

I have the dual radiator. That was also something that crossed my mind, will the stock oil pump still provide enough for both.

My oil pressure gauge right now seems to cap out at 50-55psi at 6k-red line daily driving. Currently using 0w-40 Castrol Edge Euro Formula

I'm reasonably sure the sandwich plate for the dual rad is not thermostatic. @FunnyGopher seems to agree. More research on the capability of your stock oil pump may be warranted before adding an extra cooler. Trying to cool the oil by taking away volume and pressure from your bearings may not be a good idea.

No reason to have a thermostatic plate in an oil/water intercooler(dual radiator). One would need added for an external unit

I fitted a very accurate industrial grade pressure sensor a couple of years ago, and have yet to find any noticeable difference in oil pressure after fitting the second cooler.

But they are two "conventionaly" sized coolers so I'm not sure how large the Jackson water/oil is by comparison, and how that might alter things.
