Nismo Oil Cooler Adaptor.....which Line Is In And Which Is Out?

[Sub Boy32]

I currently have a Nismo oil cooler setup on my engine which completely does away with the factory water/oil heater/cooler setup, and although it does a fantastic job of keeping the temperature cool under any conditions......it doesn't have a thermostat which means it takes ages for the temperature to come up to a nice useable 70deg+

I want to put an inline AN-12 Thermostat, but I'm not sure without pulling it apart which is the feed to the cooler, and which is the return to the engine?

Anyone know?

If it's installed and running in the car, simply run it then use an IR pyrometer to measure the temperatures of the two hoses. The hotter one is out.

Mmm.....cunning plan! Nice thinking, cheers

Or you can buy my sandwich plate with built in thermostat (which I won't be using).

From this picture showing the mounting flange of a NISMO cooler bracket this is the way i believe they flow.

Oil Pump Gallery>Bottom Line>Oil Cooler>Top Line>Filter>Main Gallery

EDIT!!

This picture shows the top (filter) flange, it clearly shown the top line returns to the input side of the filter (with the centre being the return to the main gallery).

Cheers for the pics! That's a huge help, now to find a inline thermostat.
