Hi folks,
My 2000 nissan altima has roaring noise as you driving on highway and when i start the car in the morning, it sounds like a boiling water noise,then once it warms up it doesn’t do that , I had mechanic changed my water pump and radiator flushed and the thermostat changed, also minor tune-up of spark plugs replaced at 109,000 miles. The noise noticed after the repairs were done. Also the fan stays on after shutting the engine off for a minute or 2.Can you help me out what’s causing it, I,always enjoyed your show,and its my favorite past time. Thanks again.
