We have replaced hoses and water pump and have had no problem with it getting hot. In the past week it has started to get hot, not overheated. It only happens after driving on highway when pressing the accelerator. Once you stop pressing on the gas pedal, the temperature drops. When you at a complete stop the temp drops down to the midway point on the gauge but when you go again the temp roses again.
This seems to be a faulty thermostat which is stuck partially open. Also check your coolant level on a cold engine. Use the marks on the expansion tank but do exceed the maximum mark.
