thermostat, water pump, temperature gauge, or coolant?
listen for the sound of boiling coolant (rule out temperature gauge, or coolant if present). Stop immediately, if present, and allow the engine to cool. Generally, the temperature goes higher when it is the thermostat that malfunctions as opposed to the water pump. Many water pumps are belt driven, when the belt goes, the water pump stops, and the engine will overheat, although not as high as when the thermostat won't open because you have a larger cooling resevoir. You can also check the hoses for the feel of flowing water into the radiator (functioning water pump if the thermostat is open), and a temperature differential on the input/output hoses to the engine (indicating water flow through the engine).
The best way to troubleshoot a malfunctioning thermostat for a baseboard heater is to first check the power supply, then inspect the thermostat settings and connections, and finally consider replacing the thermostat if necessary.
To fix a malfunctioning thermostat, first check the batteries and replace them if needed. Next, ensure the thermostat is set to the correct temperature and mode. If the issue persists, try resetting the thermostat or contacting a professional for further assistance.

Next, inspect the thermostat settings and make sure they are set correctly. If the issue persists, consider replacing the batteries or contacting a professional for further assistance.
the thermostat will be under the THERMOSTAT HOUSING, which is where the TOP radiator hose fits on ie(radiator to thermostat housing) this keeps the engine at an OPTIMUM temperature BUT can be A cause of OVERHEATING IF malfunctioning
