If an engine continuously runs hot, what does Technician B suggest about the thermostat?

When an engine consistently runs hot, it indicates that the cooling system is not functioning effectively, which could be due to a malfunctioning thermostat. Technician B suggests installing a cooler thermostat as a potential solution to this problem. A cooler thermostat opens at a lower temperature, allowing the engine to reach and maintain an optimal operating temperature more efficiently.

By replacing the current thermostat with a cooler one, the engine can better regulate its temperature, preventing overheating. Thermostats are critical components of the cooling system, and when they fail to open at the right temperature, they can trap coolant in the engine, exacerbating overheating issues. Thus, choosing to install a cooler thermostat addresses this issue directly by allowing more coolant to flow and aiding temperature regulation.

In contrast, options suggesting a higher temperature thermostat or leaving the existing one as is would not effectively address the overheating problem. Higher temperature thermostats would exacerbate the situation by allowing the engine to run even hotter, while leaving it unchanged would continue to allow potentially faulty operation. Checking electrical connections, although important, may not directly resolve issues related to the thermostat’s temperature regulation.
