Hot radiator

I have a 1985 Pontiac 6000 LE wagon. 2.8 V6 auto.,w/air.,carb.
207,000 miles.

The problem relates to the cooling system.
After driving for a period of time (hot or cold weather) and then turning off the key, the water boils back into the coolant jug attached to the radiator fill nozzle. Then after it cools somewhat, it sucks back into the radiator. I've replaced top and bottom hoses, radiator cap (w/lift lever), temp.sensor, thermostat (190), fuse in fuse panel, and coolant. The fan does not come on at "any" time which led me to think "It's the fan" (duh!) hence, the new sensor. However, this still did not turn the fan on. I believe the water pump is o.k. because I have pressure. There are'nt any bearing noises or leaks.(in pump or fan) My question is How do I test the fan? or do you have any other ideas? What about fan switch relay?(where located) Am stumped!

Thank-you for your suggestions and advice

Bob

Bring power from the battery to the fan. Does it work? If so, the fan is ok, and the relay or wiring to it is bad.

Thank you very much.
The fan motor was not turning on so we went and got a fan motor and it works like new. Thank you very much Joe_F
