I have a BMW 318i 1996, I have changed waterpump, viscous fan, pressure cap and removed thermostat completely and it continues to over heat...
If I am stationary the car is fine but when I'm actually driving it overheats but when I come to traffic lights or I stop and leave the engine running the temperature slowly drops back to 90 degree (halfway) as soon as I drive off it's goes straight back up again! I have all the heating, also the bottom rad hose only gets warm but when I put a hose threw the system the water circulates fine! Does n e 1 have any ideas cause I'm going mad lol, any help will be much appreciated thanks, Shaine.
