How to refill & bleed
- Ensure the engine is cool.
- Mix the coolant with distilled water to a 50/50 ratio if you are not using a pre-mixed solution.
- Slowly fill the cooling system through the degas bottle (coolant reservoir), allowing air to escape.
- Fill to the MAX line.
- Start the engine with the heater on high and let it idle.
- Monitor the coolant level and top off as needed as the system bleeds air.
- Some technicians recommend a vacuum-fill tool for a more complete air evacuation.
Common cooling system issues
While the 5th generation Ram 1500 is still relatively new, some common issues that may arise as the vehicles age include:
- Water pump failure: The water pump is a critical component that can wear out over time, leading to leaks and overheating.
- Radiator leaks: The radiator can be damaged by road debris, leading to coolant leaks.
- Thermostat issues: A stuck thermostat can cause the engine to overheat or fail to reach operating temperature.
