The normal operating temperature of a car engine can vary depending on the make and model of the vehicle. However, a temperature of 190 degrees Fahrenheit (or approximately 87 degrees Celsius) is generally within the normal range for most car engines.
Most car engines operate within a temperature range of around 180 to 220 degrees Fahrenheit (82 to 104 degrees Celsius). The engine temperature can fluctuate depending on factors such as driving conditions, ambient temperature, and engine load.
It's important to note that the temperature gauge on your car's dashboard provides a general indication of the engine temperature. If you notice any sudden or significant changes in temperature, such as overheating (above 220 degrees Fahrenheit or 104 degrees Celsius) or consistently running at very low temperatures, it may be a sign of a cooling system issue that should be inspected by a qualified mechanic.
