- New Coolant (suitable for your Nissan Micra model)
- Distilled Water
- Funnel
- Wrench or Pliers
- Drain Pan
- Safety Glasses
Procedure:
1. Preparation:
- Allow your Nissan Micra engine to cool down completely.
- Move your vehicle to a flat surface and engage the parking brake.
2. Locate Coolant Reservoir:
- Open your Nissan Micra's hood.
- Find the coolant reservoir, which is usually a translucent plastic tank.
3. Remove Reservoir Cap:
- Carefully remove the cap from the coolant reservoir by turning it counterclockwise.
- Be cautious as there may be some pressure built up in the reservoir.
4. Locate Radiator Drain Plug:
- Below the vehicle, find the radiator drain plug. Refer to your vehicle's manual for the exact location if necessary.
5. Drain Coolant:
- Place the drain pan beneath the radiator drain plug.
- Using a wrench or pliers, turn the drain plug counterclockwise to open it.
- Let the old coolant drain out into the drain pan.
- Once the coolant has drained, tighten the drain plug back into place.
6. Flush System (optional):
- If you wish, you can flush your cooling system using distilled water.
- Mix 50% distilled water and 50% new coolant in a large container.
- Pour this mixture into the coolant reservoir.
- Start your engine and let it run for about 10 minutes, allowing the mixture to circulate.
- Drain the mixture through the radiator drain plug again, letting it run until the water runs clear.
7. Refill with Coolant:
- Mix new coolant with distilled water according to the recommended ratio specified in your Nissan Micra's owner's manual.
- Use a funnel to pour the coolant mixture into the coolant reservoir.
- Continue adding coolant until the level reaches the "Full" mark on the reservoir.
8. Test System:
- Replace the coolant reservoir cap and start your Nissan Micra.
- Let it run for a few minutes and observe the temperature gauge.
- Make sure the temperature remains within the normal operating range.
9. Check for Leaks:
- Inspect the hose connections, radiator, and reservoir for any leaks. Tighten any loose connections if necessary.
10. Dispose of Old Coolant:
- Properly dispose of the old coolant and the water-coolant mixture from the flush (if performed) at a recycling center or as per local regulations.
Remember, coolant can be toxic, so it's essential to follow safety precautions and refer to your vehicle's specific owner's manual for detailed instructions.
