You are correct about your pressure guestimate, the cooler circuit
pressure is regulated (reduced) in the valve body. I suspect you will
not find a spec on cooler pressure, but if you do let me know. The
only spec I have ever seen in any model/year Toyota RM is for line
pressure under various conditions.
