The high water temperature shutdown switch protects the engine against internal damage if the cooling water temperature in the engine block is too high due to cooling water or coolant circulation problems. The switch is set to trip at 248--266°F (120--130°C). The location of the high water temperature shutdown switch is shown in Figure 2-3.
