Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and eyewear.

2. Checking Coolant Levels

Locate the Coolant Reservoir
- Open the hood and locate the coolant reservoir, typically a translucent plastic tank near the engine.
Inspect the Coolant Level
- Look at the markings on the side of the reservoir. The coolant should be between the "MIN" and "MAX" lines.
- If the coolant is below the "MIN" line, you will need to add more coolant.
Check for Leaks
- Inspect around the reservoir, hoses, and engine for any signs of leaks or damage.
- If leaks are present, they should be addressed before refilling.

3. Adding Coolant (if necessary)

Select the Correct Coolant
- Use Volvo-approved coolant or a compatible ethylene glycol-based coolant mixed with distilled water (usually 50:50).
Open the Cap
- Carefully remove the cap of the coolant reservoir. (If the engine is hot, wait until it cools down to avoid pressure release).
Add Coolant
- Pour the coolant into the reservoir until it reaches the "MAX" line.
- Avoid overfilling, as this can cause overflow when the engine heats up.
Replace the Cap
- Securely close the coolant reservoir cap.
