Pinto Car Club of America

I'm searching the diagram of the coolant circuit for a 2.3l pinto 1980. I'm not sure if mine is correctly mounted. I have compared to other 2.3 but they missing some hose compared to mine. I've got one hose going out from the water pump to the heater core. One other going from the heater core to the small exit on the thermostat cover, This line have a T adaptor going to the air intake.

I suspect an error in the mounting because my motor generate an huge amount of heat...

Any help is welcome
