Coolant seems to be coming from behind plate behind fan clutch. Is there a gasket behind there? It is a 2.2. The water pump is to the right of the fan.
Do you
have the same problem?

Possibly the thermostat but you need to have it pressure tested and follow the leak to it's source.

The thermostat housing is dry. I will pressure test it tomorrow, my tester is at work, when the motor is running the coolant is running down from above the fan pulley.

I see now where it is probably leaking. I didn't know there was a gasket where the thermostat housing bolts to front of motor.

Can you send me the picture of where the throttle cable bracket goes. I have had it apart too long to remember.
