Regular coolant maintenance is essential for a well-functioning vehicle. Ready for DIY Coolant Maintenance? Let’s dive in!


Importance of the Cooling System:

The cooling system regulates your engine’s temperature, preventing overheating and potential damage. Coolant, also known as antifreeze, plays a vital role in this process.


Step-by-Step Guide: Checking and Topping Up Coolant:

  1. Ensure the engine is cool before opening the radiator cap.
  2. Locate the coolant reservoir and check the coolant level against the “full” and “low” markings.
  3. If the level is low, add a mixture of coolant and distilled water to the reservoir.
  4. Replace the reservoir cap securely.


Importance of Coolant Flush and Refill:

Over time, coolant can become contaminated and less effective. A coolant flush and refill is recommended to maintain the cooling system’s efficiency.


Step-by-Step Guide: Performing a Coolant Flush and Refill:

  1. Consult your vehicle’s manual for the recommended coolant type and mixing ratio.
  2. Lift the vehicle and place a drain pan under the radiator drain plug.
  3. Open the radiator drain plug and allow the old coolant to drain.
  4. Close the drain plug and fill the radiator with the new coolant mixture.
  5. Start the engine and let it run with the radiator cap off until the thermostat opens.
  6. Top up the coolant level if necessary and replace the radiator cap.


By following these cooling system maintenance steps, you’re safeguarding your engine from overheating and potential damage. In the final article of our series, we’ll guide you through DIY brake inspection and pad replacement, so stay tuned!
