Abstract: An engine temperature monitoring device for alerting a vehicle operator that an engine is overheated includes a heat sensor adapted for detecting ambient temperature levels. A processor adapted for monitoring the temperature levels is operational coupled to the heat sensor. A speaker for producing an audible sound is operationally coupled to the processor. The speaker is turned on when the heat sensor detects a temperature of the engine which is greater than an acceptable tolerance. A power supply is operationally coupled to the processor. The heat sensor is secured to the engine such that the heat sensor may detect the temperature of the engine.
