took way longer because had difficulty reaching places and disconnecting a bunch of stuff
but at least it got done

but ... did i mess something up while i was swapping out the TA's?
or was it just time?

when you say thermostat, are you referring to the coolant temperature sensor?
where exactly is it located? is it in the photo i put up?
The temperature sensor is a small connector on the top front of the motor. It is located in the thermostat housing (the large coolant hoses feed into it). One needs to disconnect the sensor when getting slack in the wires to remove the actuators. If you look at about the 4:50 mark in this DIY video he points it out.
