* Year and Model: The E320 was produced for many years, with different engine types and cooling systems. The temperature range could vary significantly between model years.
* Operating Conditions: Factors like ambient temperature, load on the engine, and coolant condition all influence the actual engine temperature.
* Gauge vs. Actual: The temperature gauge in your car provides a general idea, but the actual engine temperature is measured by sensors.
Here's how to find the right information for your E320:
1. Consult your Owner's Manual: The manual for your specific E320 model year will contain the correct operating temperature range for your engine.
2. Look at the Gauge: The temperature gauge in your car will usually have markings indicating the normal operating range.
3. Use an OBD-II Scanner: A scan tool can provide accurate real-time data on your engine temperature and other parameters.
Important Note: If your E320's engine is consistently running too hot or too cold, it could indicate a problem with the cooling system. It's best to have a mechanic diagnose any unusual temperature readings.
