You will then start to smell burn't coolant coming from your hood, and driving your car, will be impossible.
My point? The fact that your oil temp is at 240F, and not moving much at any given moment, is because the water pump is continuously pumping 9000L/Hr, through your cooling system. Even when you shut off your car, your water pump still runs. I know the tendency is to get stuck on oil temps, and oil coolers, but when, your water pump fails, you will know what I'm talking about, and why I'm currently obsessed with it.
