Removing the Radiator Cap
Before adding coolant, you need to remove the radiator cap to access the cooling system. Make sure to use a radiator cap wrench to prevent any damage to the cap or the radiator.
Locate the radiator cap on the top of the radiator and position the wrench on it. Turn the wrench counterclockwise to loosen the cap, and then lift it off.
Draining the Cooling System (Optional)
Depending on the type of coolant you are using and the condition of your cooling system, you may need to drain the existing coolant before adding new coolant. This is typically done when switching from a different type of coolant or when the cooling system has been contaminated with debris or rust. (See: My Coolant Finishing Quick)
Use a coolant drain pan to catch the old coolant and position it under the radiator. Locate the drain valve on the bottom of the radiator and open it by turning the valve counterclockwise.
Allow the coolant to drain completely before proceeding with the next step.
Adding Coolant to the Cooling System
Once the radiator cap is removed and the cooling system has been drained (if necessary), it’s time to add the new coolant. Locate the coolant reservoir on the side of the engine and check the level of the coolant.
Using a 50/50 coolant mixture, pour the new coolant into the reservoir until it reaches the recommended level. Make sure not to overfill the reservoir, as this can cause damage to the engine or the cooling system.
Replace the radiator cap and start the engine. Allow the engine to run for a few minutes to circulate the new coolant throughout the system.
Checking the Coolant Level and Pressure
After the engine has been running for a few minutes, turn it off and check the coolant level again. If the level has dropped, add more coolant as needed to reach the recommended level.
Use a multimeter to check the pressure of the cooling system. If the pressure is below the recommended level, you may need to add more coolant or have the system pressure tested by a professional mechanic.
Final Checks and Maintenance
Before putting the vehicle back in service, perform a final check of the cooling system to ensure it is functioning properly. Look for any signs of leaks or damage to the radiator, hoses, or other components.
Additionally, make sure to check the coolant level regularly and top it off as needed to prevent any damage to the engine or the cooling system.
By following these steps and taking the necessary precautions, you can ensure the longevity and performance of your Duramax engine’s cooling system.
