If your car or truck has a gauge that displays the temperature, it is safe to assume the 195 to 220-degree range is normal for your vehicle. Vehicles equipped with a temperature gauge will almost always have a noticeable red line to warn you when your engine is too hot.
Where should my temp gauge be at in my car?
Temperature Gauge is Normal When the engine is functioning, and the coolant is doing its job, the temperature gauge needle should be somewhere in the middle between the hot and cold indicators.

The engine is overheated when it reaches a temperature of 231 degrees. Damage may occur if the temperature is above 245 degrees Fahrenheit.
Is 230 too hot for an engine?
So, 230 degrees F is acceptable. The cooling system in your car is designed to run above 212 degrees F by using a pressurized system. The radiator can remove more heat when it is hotter than the outside air temperature. If the gauge on the dash gets into the red zone, turn on your cars heater to remove additional heat.
Is 250 degrees to hot for an engine?
You can run your car at 240 or 250 degrees without hurting anything, as long as the water in the radiator doesn’t boil. Your main concern should be to keep your engine below the boiling point of your coolant. If your radiator cap is no good, it will lower the boiling point of your coolant to 212 dgrees.

What temperature will damage an engine?

Why is my engine hot but not overheating?
This problem can be due to a low coolant level in the radiator, a faulty thermostat, a bad radiator, a damaged head gasket, a faulty water pump, or it might just be a bad temperature sensor or gauge giving a false reading.

At what temperature does a motor overheat?
As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur. As heat continues to increase, the different rates of thermal expansion cause metal to distort.

Radiator cooling fan Park your car in the shade. Use car window shades. Tint your windows. Leave car windows open slightly. Turn the floor air vents on. Use the fresh air setting instead of recirculation on your A/C. Keep your eye on the car temperature gauge. Turn on the heat to cool the engine.
