I do not have a diagram of the cooling system itself, but I providied you with the wiring diagram. The cooling system is pretty simple. Water flows out past thermostat, when open, into radiator and out back into block. it runs through coolant circuit and past water pump then it flows through the Idle Air Control Valve and the Fast Idle Thermo Valve, located on intake manifold the throttle body almost on op of each other you will see coolant lines. The it runs in and out of the heater core, if valve is open otherwise this is a closed circuit. Then back into block past coolant snesors and back to the thermostat.
