ok not really making 100% sense, if i drive it at 50mp it doesn;t over heat, as soon as i go higher te temp gauge starts shooting up, stays in the red for a min or 2 then comes down slowly and keeps going back and forth like that. seems strange that it keeps perfect temp at 50mph, heating blows hot once car warms up so thermostat is opening. seems like reduced coolent flow, any suggestions on what to check?
