B-1, 4-1-7 is an easy fix. Just pop off the cover behind the passenger side grab handle and vacuum out the dust bunnies.

Because the engine fan comes on when you turn on the AC, the electrics are probably hooked up correctly. You can check the resistance by unplugging the ECT sensor and probing the sensor with a multimeter. You should get the following resistance when the coolant temp is at:
32F = 7200 ohms
68F = 2800 ohms
104F = 1200 ohms
212F = 150 ohms

The code in A-2 for a non-working ECT sensor is 1-2-3.

Also wonder about the overflow bottle itself. Inspect the top carefully if it is leaking below the cap, it might not be sealing completely.
