Herein, where should my temperature gauge sit?
The ideal engine temperature should be somewhere between 195 and 220 degrees. An engine is operating normally when the needle points at the center or near the center of the gauge. Don't worry if the needle does not exactly sit in the middle of the gauge.

- Temperature gauge reading very high and engine overheating. The first and potentially most alarming symptom will be the temperature gauge reading high into the red within the first 15 minutes of your vehicle engine running.
- Temperature changing erratically.
- Coolant leaks around the thermostat housing or under the vehicle.

As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur.
What does the C and H mean in my car?
