I just replaced the thermostat, thermostat housing, and new radiator. Just did an oil change, new spark plugs, and just replaced valve cover gasket. Don't know what the problem is but it seem to be smoking out the top of the radiator. Any idea what it could be? Could it be the water pump?

Good afternoon,

If it steams out the top of the radiator, it sounds like it could be a failed head gasket in the motor. They fail when the engine overheats and leaks compression into the cooling system.

I would have a compression test done to see if there is any coolant movement in the radiator during the test.

Also, have the radiator tested for any leaks.

As far as the water pump, yes, if the water is not circulating it could cause the issue.
