When the engine's temperature is climbing off the charts, you should check your Lexus Sc400 water pump for damage. Operated via a belt, the water pump streams coolant by means of centrifugal force within the engine bay for optimum cooling effects. When there's insufficient air getting inside the grille, your car will most likely heat up extremely and the cab will not be properly aired out.
You know your Lexus Sc400 water pump is about to break once you hear that unmistakable squeak, which means it requires some fixing. Coolant can drip out of the water pump's weep hole if the gasket is already ripped. Once the water pump's bearing, pulley, or the entire unit comes apart, you'd better avoid taking your ride out for a spin until this is restored (unless you it's all right for you to risk engine overheating). To prevent the engine from getting too hot, it's highly advised that you fix the broken gasket of your water pump or upgrade the pump itself for your own safety and convenience. You must get a heavy-duty replacement unit-one that's uniquely tailored for your automobile's engine cooling system for perfect fit and great quality.
