How to service the thermostat for the 4.0L SOHC engine on 2002 Ford Explorer?

Each service operation for the 4.0L SOHC engine thermostat begins with draining the engine cooling system. The upper radiator hose must be taken off first followed by unscrewing both bolts securing the water outlet adapter and thermostat. Verify the condition of the O-ring seal before changing it with a new one. The installation process ends by performing the opposite sequence of removal steps.
