hey all i have an 1992 excel its been a cracking little car for 900$ i have been faced with overheating today i have changed the thermostat and flushed with new coolant but still runs real hot just below the white line or on the white line its not the head i dont think its not running white smoke or blue smoke and its not bubbling in the rad.also if i idle the heaters on hot it blows hot and then blows cold im confused i dont no were to go the bottom hose is hot and the top hose is hot fan works but dose not cool it down
