HOT WIRE COOLANT FAN. STILL DONT TURN ON REPLACE FAN ASSEMBLY. IF COOLANT FAN DOES TURN ON WHEN HOT WIRED.CHECK THE FAN RELAY OR FUSE ALSO SCAN VECHICLE FOR FAULTY COOLANT TEMPERATURE SENSOR IF ENGINE COOLANT TEMPERATURE IS 190 DEGREES AND SCANNER SHOWS 80 OR LOWER COOLANT TEMPERATURE SENSOR FAULTY.
Either it is low on fluid and coolant not reaching temp sender or temp sender is bad or check fuse and or relay for fan is the first step. Also, some cars have a fusible link that can go bad.

it is mounted under the radiator towards the drivers side,it is flat and held to the frame with 2 small bolts and has a flat wire connector,it doesnt look like a normal relay,its black with a silver plate on the front of it,hope this helps
Testimonial: "awesome found it immediately........thank you"
SOURCE: Where is the drain valve on 2002 dodge caravan radiator?
its a pitcock facing the cab bottom of the radiator, plastic flat. once you find the pitcock just put a bucket underneath and turn it.then refill. if you want to flush(run fluid thru to clean it out) the radiator id suggest taking it in. you dont have to flush it every time you change the coolant out.

First thing I would check is the fuse or the fan relay, located in the power distribution box under the hood. If that's not the problem, then I would find the coolant temperature sensor, unplug it with the key on and the fans should run.
