I'm panicking to get my rotary Corolla finished for racing tomorrow. I cannot for the life of me find a cooling system routing diagram.

I've got an FD rad in the car, I'm not running a heater core, but I do have the stock 12a water fed oil cooler. The FD rad has an upper and lower main outlets, but on the lower one, there is a secondary smaller outlet that I believe runs to the oil cooler. I am unsure how how to route this to ensure nice cool water is helping reduce oil temps.

Any help ASAP would be great! Hopefully someone has a diagram.

the smaller outlet goes to a metal line, than splits to the heater core and oil cooler. So you need to just go from the small outlet to the top of the oil cooler than from the bottom of the oil cooler to the motor.

So the smaller secondary outlet from the bottom of the rad splits running one hose to the top or bottom of the oil cooler? And the other hose to where? The T joint on the block?

The small secondary outlet from the rad goes to the top of the beehive oil cooler. The bottom of the beehive oil cooler connects to a "T" on the engine block just below it. The large lower outlet from the rad connects to the front cover of the engine block

just to try another stab at this, the previous people are right, but just to say it a different way might help.

on a stock 12A the coolant comes out of the back of the engine and T's off. half goes to the cooler and half goes to the heater, then they both T back in and end up at the bottom of the radiator.

if you have no heater, you can go from the rear of the engine, to the cooler to the lower radiator/lower radiator hose.
