Q: Cooling fans not working

asked by on January 09, 2017

I have replaced the cooling fans,thermostat,cylinder head temperature sensor,relays and fuses and lower radiator hose. Van doesn't overheat. The heat inside works but lower radiator hose is cold and upper is hot. I know it could be the thermostat but I think it's loaded with air. I tried jacking it up and letting it run with expansion tank cap off. No luck. Any help is greatly appreciated. Thanks Ken
