Recently my thermostat housing began to leak due to a crack around the gasket. The crack was between the housing and the engine. The housing was replaced as well as the gasket, thermostat, and the thermostat gasket. For the first week the car ran fine until one day on the highway it began to overheat. After this happening on a few occasions I realized that the car only overheats when driving on the highway, or in excess of 60 mph. Also, before the parts were replaced the car was not overheating. What could be the cause?
