The temp gauge shows close to red zone on a 82 degree celcius thermostat. Radiator sounds like its boiling. Botton radiator hose is cool. When thermostat is removed it appears to run at correct temperature. The thermostat has been checked and changed it appears to be working. Anything else to check? Any help would be great Thank You.

Check the radiator if its clogged and water pump circulating coolant thru out the engine engine if okay could be airlock try bleeding it don't work get it block and pressure tested to rule out a blown headgasket, cracked head or block.
