Engine Cooling System

The engine cooling system functions to eradicate excessive waste heat from the automobile’s engine in order to maintain its optimum level of functioning at a temperature that promotes its maximum efficiency. While the engine cooling system not only reduces accumulation of damaging heat, it also maintains the minimum temperature after the engine starts reducing the possibility of high engine temperatures that cause damage to engine parts and lubricants. Sometimes an engine tuning might reveal this issue.

How to Manually Flush an Engine Cooling System

Park the automobile in a place away from children and animals.

1. As you park, make sure the following is completed:

  • The engine is cold.
  • The ignition is off.
  • The parking brake is on.

2. Place a pail below the drain valve located at the bottom of the radiator.
3. Open the drain valve and let the liquid drain directly into the pail.
4. Place the drained liquid inside tight-fitting lids containers, label it as “coolant”, dispose it safely, and close the drain valve.
5. Open the radiator cap and pour water to fill the radiator. Turn the engine on with the heater control set on High for 10 minutes.
6. Turn off the engine and allow it to cool off. By the time the radiator is cool enough, get the water out of the engine by draining it into the pail. Transfer the residue from the pail to a sealed container, label it as “toxic”, and dispose it properly.
7. Close the drain plug and fill the engine with water and cooling fluid. Continue pouring until you reach the “MAX” line located on the coolant reservoir.
8. Evenly disperse the water and the coolant throughout the engine. Change the radiator cap and run the engine with the heater on High until the temperature gauge reads in the normal range.
9. Turn the engine off and clean it.
10. Recheck the coolant level in the reservoir after a few days and add equal distribution of water and coolant if the level gets low.
11. If all else fails be sure to call your favorite Engine Cooling System Specialist.
