Stop/Start Not Ready Engine Temperature Too Low Dodge Durango

If your Dodge Durango is showing a “Stop/Start Not Ready” message due to low engine temperature, it may indicate a problem with the engine’s cooling system. Low temperatures can prevent the engine from reaching the ideal operating conditions for the stop/start feature to function properly.

The Dodge Durango is equipped with a stop/start system that shuts off the engine when the vehicle comes to a complete stop, then restarts it when the brake pedal is released. However, if the engine temperature is too low, it can disrupt this process and trigger the “Stop/Start Not Ready” message.

To address this issue, it’s important to ensure that the engine coolant is at the proper level and that the thermostat is functioning correctly. Additionally, it may be beneficial to have the vehicle inspected by a qualified mechanic to diagnose any potential underlying issues with the cooling system.

Spot The Symptoms

If you are experiencing unexpected shutdowns, inconsistent start/stop behavior, or dashboard warning signals in your Dodge Durango, the issue could be related to the engine temperature being too low. These symptoms may indicate that the stop/start system is not ready due to the engine temperature being below the optimal operating level. It is important to address these symptoms promptly to avoid potential malfunctions and ensure the proper functioning of your vehicle.

Essential Diagnostic Tools

OBD-II Scanner

Using an OBD-II scanner can help identify any fault codes and provide valuable diagnostic information. This tool plugs into the car’s onboard computer system and retrieves data related to the engine temperature, allowing for quick and efficient troubleshooting.

Temperature Gauges

Utilizing a temperature gauge is essential for monitoring the engine’s temperature. This tool provides real-time readings, enabling the detection of any fluctuations or inconsistencies that could indicate a problem with the engine’s temperature.

Manufacturer’s Manual

The manufacturer’s manual contains valuable information regarding the recommended operating temperature range for the Dodge Durango’s engine. It also includes specific diagnostic procedures to address issues related to a too low engine temperature and provides guidance on necessary corrective actions.

Check Engine Coolant Levels

When it comes to checking engine coolant levels in your Dodge Durango, there are a few key steps to follow. Firstly, locate the coolant reservoir and ensure it is filled to the recommended level. Inspect for any leaks in the system that may be causing a loss of coolant.

Additionally, it’s important to verify the coolant concentration to ensure it is at the correct mixture for optimal engine temperature. By following these steps, you can ensure that your engine is not experiencing issues related to low temperature and is ready to perform as expected.

Review Thermostat Operation

Thermostat’s role in engine temperature is crucial for maintaining an optimal operating temperature. A faulty thermostat can lead to various issues, including poor fuel economy, overheating, and increased engine wear.

Symptoms of a faulty thermostat may include a lower than normal operating temperature, slow warm-up of the engine, or overheating. To test the thermostat, one can use a thermometer to check the operating temperature, inspect the radiator hoses for temperature variance, or perform a resistance test.

It’s important to address any thermostat issues promptly to avoid potential engine damage and ensure the proper functioning of the vehicle.

Inspect Battery Health

The battery’s impact on the stop/start system is crucial. Testing the battery voltage is essential to ensure its optimum performance. If the voltage is below the standards, it is recommended to replace the battery to maintain the functionality of the stop/start system.

Suggested Engine Warm-up Practices

It is important to allow your Dodge Durango to warm up properly before driving, especially in colder temperatures. This can help enhance engine performance and prevent damage. The suggested warm-up time varies depending on the outside temperature, but as a general rule, it is recommended to let the engine idle for at least 30 seconds and up to a few minutes.

This allows the engine temperature to rise and reach optimal levels before driving. Additionally, it is advisable to avoid revving the engine excessively during the warm-up period and to drive gently for the first few miles.

By following these optimal driving behaviors and adhering to engine warm-up time recommendations, you can help ensure the longevity and efficient operation of your Dodge Durango.

Preventive Maintenance Schedule

Ensure your Dodge Durango’s Stop/Start system functions optimally by scheduling regular maintenance. Engine temperature could be too low, affecting its performance. Follow a preventive maintenance schedule to prevent potential issues and keep your vehicle running smoothly.

Regular Coolant Fluid Exchanges

Regular coolant fluid exchanges are crucial for maintaining the optimal functioning of your Dodge Durango. Ensuring that the coolant is clean and at the appropriate level helps prevent overheating and potential damage to the engine.

Thermostat Inspection Intervals

Regularly inspecting the thermostat of your Dodge Durango is essential to verify its proper functioning. It is recommended to adhere to specific inspection intervals to prevent issues related to engine temperature.

Adapting To Climate Changes

Special considerations for cold climates

When driving in cold climates, it is important to pay attention to the engine temperature of your Dodge Durango. In colder weather, the engine may not reach the optimal operating temperature, leading to issues such as the stop/start system not being ready.

To address this, engine block heaters can be used to pre-warm the engine, allowing it to reach the necessary temperature more quickly. This is particularly important for vehicles that are frequently started and stopped in cold weather conditions.

By using engine block heaters, drivers can ensure that their Dodge Durango is ready to perform efficiently, even in low temperatures.

FAQ On Stop/start Not Ready Engine Temperature Too Low Dodge Durango

What Does It Mean When The Engine Temperature Is Too Low?

When the engine temperature is too low, it can indicate a faulty thermostat or a cooling system problem. This can lead to decreased fuel efficiency and increased engine wear. It’s important to ensure proper engine temperature for optimal performance and longevity.

Regular maintenance can help prevent these issues.

Why Is My Car Running At A Low Temperature?

A low car temperature could be due to a faulty thermostat or low coolant levels. It may also indicate a problem with the coolant system or a malfunctioning radiator fan. Regular maintenance and inspection are crucial to ensure optimal engine temperature.

Why Is My Engine Not Reaching Normal Operating Temperature?

The engine may not reach normal operating temperature due to a faulty thermostat, low coolant levels, or a malfunctioning temperature sensor. These issues can cause inefficient fuel combustion and increased engine wear. It’s important to address these issues promptly to prevent further damage.

Why Is My Car Temperature Low When I Start It?

When you start your car, the temperature may be low due to the engine needing time to warm up. This is normal and allows the engine to reach its optimal operating temperature. Proper maintenance can also help ensure your car’s temperature stays within the recommended range.


The issue of a “Stop/Start Not Ready Engine Temperature Too Low” in the Dodge Durango can be frustrating. Understanding the potential causes and knowing the steps to rectify the problem can help you maintain the optimal functioning of your vehicle.
