Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear gloves and safety goggles.

2. Locate the Coolant Reservoir

Open the hood and secure it with the prop rod.
Identify the coolant reservoir, which is a translucent tank typically located near the radiator.

3. Check Coolant Level

Inspect the side of the coolant reservoir for the "MIN" and "MAX" level indicators.
If the coolant is below the "MIN" mark, proceed to refill.

4. Refilling the Coolant

Remove the cap from the coolant reservoir by twisting it counter-clockwise (ensure the engine is cool to avoid pressure release).
Using a funnel, pour the appropriate Honda Type 2 Coolant until it reaches the "MAX" mark.
If adding coolant, ensure the mixture is correct (if using concentrated coolant, mix with distilled water as per the manufacturer's instructions).

5. Check for Leaks

After refilling, inspect the hoses and connections for any signs of leaks.
Replace the reservoir cap securely.

6. Final Steps

Start the engine and let it idle for a few minutes to circulate the new coolant.
Monitor the temperature gauge and check for any abnormal signs.
