Where is the thermostat located on a 1994 Ford Ranger?

In both the 4 & 6 cylinder models follow the upper radiator hose to the engine block, the piece it connects to is the cover with the thermostat in it. I just did the a 94/4.0 V6 and the bolts are a bit tight to access. Ensure you have a flex socket handle. I found the steps in the Haynes manual for this vehicle.
