    If you are sure it is the overheat and not fuel restriction, check the heat sensors as per your manual. How are you verifying the temp? May be a t stat stuck shut.

    i did verify temp properly last night under load with temp gun. It is in fact overheating on the port side. Tapped on the theremostat cover & temp gradually went down. Possibly a sticking thermostat ???
