this sounds like a water blockage, take off the water hose that goes to the engine block, start the engine, and see if there is water flow going to engine...if this is the problem, then you need to buy an engine flush fluid, and flush out your engine....please be carefull, as the E36 320i, has an aluminium head, and is easily warped by heat
